Mad cow disease: See Bovine Spongiform Encephalopathy (BSE).

Madigan Award: See Edward R. Madigan Agricultural Export Excellence Award.

Mailbox price (dairy): The net price received by dairy producers for milk including all payments received for milk sold and deducting the cost associated with marketing the milk.

Mainland allotments (sugar): See Sugar (marketing) allotment(s).

Mainland state(s): Under the Farm Security and Rural Investment Act of 2002 (Sec. 1403), for purposes of the flexible marketing allotments for sugar, all sugarcane-producing states except for the offshore states of Hawaii and the Commonwealth of Puerto Rico. See Sugar (marketing) allotment(s).

Major crops: Include almonds, apples, barley, canola, carrots, corn (field and sweet), cotton, grapes, hay (alfalfa and other), lettuce, oats, oranges, peanuts, pecans, popcorn, rice, rye, snapbeans, grain sorghum, soybeans, sugarcane, sugarbeets, tobacco, tomatoes, sunflowers, and wheat. See Minor crops.

Major sugar countries: Under the Farm Security and Rural Investment Act of 2002 (Sec. 1401(c)(4)(B)), countries of the European Union and the ten foreign countries not covered by the Uruguay Round Agreement on Agriculture that the USDA determines produce the greatest quantities of sugar.

Make allowance: In determining the Class III price and Class IV price, the USDA uses a monthly survey of the wholesale price and determines the farm value of the milk that went into the manufacturing of the cheese and butter (the weighted average of the most recent California Department of Food and Agriculture study and the Rural Business Cooperative Service study). Before determining the farm value, the formula subtracts from the wholesale price of cheese or butter a make allowance that represents the cost to processors for converting the milk into cheese or butter. There is an inverse relationship between the make allowance and the Class III price and Class IV price; that is, the higher the make allowance is set, the lower the minimum Class III price or Class IV price paid to producers. Since the higher of the Class III or Class IV price is also used as the base price for Class I milk, it might also mean lower prices for Class I milk.

Making Continuing Appropriations for the Fiscal Year 1987, and for Other Purposes (P.L. 99-591): Signed into law October 30, 1986. The law, in addition to providing funding for federal programs, modified the Food Security Act of 1985 by limiting program payments to $50,000 per person for deficiency payments and paid land diversion payments, and included honey, resource adjustment (excluding land diversion), disaster, and Findley payments under a $250,000 payment limitation.

Malt: grain, usually barley, that has been germinated through a soaking process and then dried. Malt is used in brewing and distilling, and as a nutrient additive.

Managed production: Vertical agricultural system utilizing advances in science and technology to maximize quantity, quality, and safety. See Factory farm.

Management-intensive grazing: See Managed grazing.

Mandatory entry: Under previous farm bill authority, the USDA had to make Farmer-Owned Reserve (FOR) loans available to producers of wheat and feedgrains if the average market price for the respective crops of wheat or corn, during an applicable 90-day period, was less than 120 percent of the current loan rate and stocks-to-use levels (37.5 percent for wheat and 22.5 percent for corn) were above the threshold amount. The FOR was suspended by the Federal Agriculture Improvement and Reform Act of 1996.

Mandatory grant(s): grant that a federal agency is required by statue to award if the recipients meet the eligibility and compliance requirements. The amount of the award is usually determined by measuring need based on such factors as population, per capita income, and various program-specific factors. These grants are typically awarded to state governments and sometimes to other entities. They include open-ended grants, close-ended grants, and block grants. See Grant(s).

Mandatory identification: State and/or federal identification requirements that define which livestock must be identified according to established protocols.

Mandatory inspection (grain): See Grain inspection.

Mandatory program(s): program that requires all producers to participate if they wish to produce and market a designated commodity without prohibitive penalty. The U.S. tobacco program and peanut program are examples of mandatory programs.

Mandatory spending: Funding provided by permanent law rather than annual appropriations. The level of spending can be changed with respect to the eligibility criteria or the payment formula, but annual action is not necessary to ensure the continuation of spending. Also Direct spending. See Discretionary spending.

Mandatory spending (agriculture): Approximately three-fourths of total USDA spending is classified as mandatory, which by definition occurs outside the control of annual appropriations. Eligibility for mandatory programs is usually written into authorizing law, and any individual or entity that meets the eligibility requirements is theoretically entitled to the benefits authorized by the law. Currently accounting for the vast majority of USDA mandatory spending are the Food Stamp Program (nearly one-half of total USDA mandatory spending), child nutrition programs, the farm commodity price-support programs and income support programs, the Federal Crop Insurance program, and the Conservation Reserve Program. See Entitlement(s).

Mandatory supply control(s): program that would prohibit producers from producing or selling more than specified amounts of certain commodities without penalty. All producers of any controlled commodity would be required to participate, with fines or other legal penalties used to enforce restrictions.

Manufactured milk products: See Manufactured dairy product(s).

Manufacturing (grade) milk: Grade B milk or the Grade A milk assigned to Class II, Class III, and Class IV, or otherwise used in the production of manufactured milk products. See Dairy products (eligible), Manufactured dairy product(s), and Storable manufactured dairy products.

Manure storage facility: A permanent structure or facility, or portion of a structure or facility, utilized for the primary purpose of containing raw or untreated manure.

MAP: Market Access Program

Marbling: The intermingling of white flecks of fat within the meat muscle (lean). The greater the amount of marbling, the higher the grade because marbling makes meat more tender, flavorful, and juicy. Although consumers equate marbling with palatabilityand tenderness, increasing concerns regarding animal fat in the diet have caused consumers to place greater weight on the perceived health benefit from fat reduction than on assurances of tenderness or palatability. Consequently, consumers now demand minimal visual fat, while still desiring a palatable product. Also intramuscular fat.

Mare: A female horse that is older than four years of age.

Marek’s disease: A cancer disease of poultry.

Margin: In a cooperative, monies in excess of net operating costs.

Margins generally run about 10 percent of contract value and must be maintained at a specified minimum level while the trade or hedge exists. See Clearing margin(s), and Customer margin(s).

Margin call(s):m In commodity options or futures trading, a call for additional margin from a clearinghouse to a clearing member or from a brokerage firm to a customer when funds in a futures or hedging account fall below levels required by a brokerage firm.Margin minimums are set by the exchanges. However, a brokerage firm can set them above the minimum.

Mariculture: Marine (ocean) aquaculture; farming the sea for plant and animal crops that are valuable as food or for industrial processes.

Marine leg: A steeply inclined conveyor belt with scoops bolted on it that is used to scoop grain out of a barge and elevate it. See Belt(s), Leg, Sampler, and Tripper.

Mark: See Marking, and Official inspection legend.

Market access: The extent to which a country permits imports. A variety of tariff and nontariff trade barriers can be used to limit the entry of foreign products.

Market Access Program (MAP)l: program authorized by the Agricultural Trade Act of 1978 (Sec. 203) and formerly known as the Market Promotion Program. The Federal Agriculture Improvement and Reform Act of 1996 renamed this nonprice promotion program andauthorized spending of up to $90 million annually through FY2002. The FAIR Act prohibited the provision of direct branded product assistance to foreign companies promoting foreign-produced products or to companies not recognized by the Small Business Administration as small businesses (with the exception of cooperatives, associations of agricultural producers, and nonprofit trade associations). Under the Farm Security and Rural Investment Act of 2002 (Sec. 3103), the authorized spending level was gradually increased up to $200 million per year by FY2006 and FY2007. Also, for funding in excess of the FY2001 level, equal consideration will be given to both organizations that have participated and those that have not participated in the past and to activities in both emerging markets and markets other than emerging markets. The program uses funds from the Commodity Credit Corporation and is administered by the Foreign Agricultural Service. Market promotion programs are not subject to Uruguay Round Agreement on Agriculture restrictions. See Market Promotion Program (MPP).

Market administrator (milk): The administrator of each federal milk marketing order. The duties performed by the market administrator are specified in each order. These duties include computing and publishing class and uniform prices as well as other required prices andbutterfat differentials, verifying handler reports and payments, preparing statistics and information concerning operations under the order, keeping records and books that clearly reflect the transactions provided for in the order, and disseminating this information to the public. The market administrator also receives and investigates any complaints of violations of the order.

Reports include information on prices, volume, quality, condition, and other market data on farm products in specific markets and marketing areas. Reports cover both domestic and international markets. The data is disseminated within hours of collection via the internet and made available through electronic means, in printed reports, by telephone recordings, and through the news media.

Market order: In commodity futures trading, an immediate order to buy or sell a futures contract. See Stop order, Stop-limit order, and Time-limit order.

Market price(s): The amount received or paid for a unit of a commodity. Most market prices for U.S. agricultural commodities are quoted in pounds, bushels, dozens, quarts, gallons, tons, or hundredweight. Other countries use different measures including grams, kilograms, liters, and long tons. See Weights, measures, and conversion factors.

Market Promotion Program (MPP): An export promotion program authorized by the Agricultural Trade Act of 1978 (Sec. 203) and first established as the Targeted Export Assistance (TEA) Program under the Food Security Act of 1985. It was reauthorized in the Food, Agriculture, Conservation, and Trade Act of 1990 and renamed the Market Promotion Program. The MPP was designed to encourage development, maintenance, and expansion of commercial farm export markets. Unlike TEA, the MPP did not restrict assistance to U.S. producer groups or regional organizations whose exports had been adversely affected by a foreign government’s policies, although these cases received the highest priority. The program promoted exports of specific U.S.commodities or products in specific markets. Under the program, eligible participants received generic commodity certificates in payment for promotional activities approved by the USDA. The program was reauthorized again in the Federal Agriculture Improvement and Reform Act of 1996 and renamed the Market Access Program.

Market risk: The perils that affect the prices received for a farm’s production, and the prices paid for the inputs used in producing farm commodities.

Market service association (bargaining association): A service-type bargaining association that generally is involved with providing market supply and demand data to its members on a timely basis. This type bargaining association is more accurately described as the forerunner to a full-fledged bargaining association. The service organization does not engage in direct bargaining with buyers, but will maintain contacts with the trade to keep up to date with marketing and buying activities.

Market share: A proportion of the total sales or business in a given market.

Market shed: The area where the producers are located who supply a given city or metropolitan area with practically all the milk used for table purposes.

Market support tools: Activities of a research and promotion order or a marketing order that attempt to influence demand through improving both the buyers’ and sellers’ knowledge of a product’s availability and uses.

Market viability grants: See Farm Viability Program.

Market(s): (1) To dispose of commodities in raw or processed form, by voluntary or involuntary sale, barter, exchange, gift inter vivos, or by feeding to poultry or livestock. (2) A place for the establishment of price for commodities bought and sold. (3) The potential universe of buyers and customers. (4) The bringing together of buyers and sellers. (5) Under the Livestock Mandatory Reporting Act of 1999, the sale or disposition of swine, pork, or pork products in commerce. See Marketing.

Marketing and Regulatory Programs: The USDA mission area that includes the Agricultural Marketing Service, Animal and Plant Health Inspection Service, and Grain Inspection, Packers and Stockyards Administration.

Marketing area: The geographic territory covered by a federal milk marketing order in which the handling of milk is subject to the terms of a marketing order. The area is clearly specified in the marketing order. Milk dealers conducting business in the area are subject to regulation.

Marketing assessment(s): See Assessment(s) program(s), Peanut marketing assessment(s), and Sugar marketing assessment(s).

Marketing assistance loan(s): See Nonrecourse loan(s).

Marketing associations (cotton): Traditionally, farmer-owned organizations that sell cotton produced by the member producers to mills overseas.

Marketing associations (peanuts): Under the former peanut program, three regional marketing associations administered the program acting as agents for the USDA. The associations kept records of quota and additional peanuts marketing, arranged warehousing for Commodity Credit Corporation loan peanuts, and operated the price-support loan program. Each regional marketing association sold and disposed of acquired quota peanuts at not less than specified price levels and of acquired additional peanuts at market prices. To get the support price, a producer placed peanuts in storage arranged by the regional marketing association. Once completed, the producer no longer had control over the peanuts; they were part of a pool controlled by the marketing association and the CCC. The regional marketing associations operated independently although they shared in each others’ losses. The Farm Security and Rural Investment Act of 2002 eliminated the peanut quota system. Producers can receive nonrecourse marketing assistance loans or loan deficiency payments through either an approved marketing association or directly from the Farm Service Agency. See Cooperative Marketing Association Program (CMA).

Marketing associations (tobacco): See Price stabilization cooperative(s).

Marketing board: (1) A major form of government involvement in commodity marketing in some countries such as Canada and Australia. These boards generally handle all export sales for the commodity. They may administer provisions to guarantee producers a minimum price each year based on the cost of production, or provide an initial minimum price with supplemental payments later based on export sales. Boards may oversee a two-price plan in which domestic prices differ from the export price. Canada and Australia use marketing boards for selected grains, and Australia operates a wool marketing board. (2) A central government authority that directs the marketing of a commodity. Export management is the most frequently performed function. Producers give up their right to the commodity at harvest; all storage and marketing functions are managed by the government authority. Producers receive an advance on commodities delivered or stored on the farm, with subsequent payments being made as marketing is completed. All producers receive the same price, adjusted for location and quality differences. Marketing boards have traditionally been used in the United Kingdom, Canada, and Australia but never in the U.S.

Marketing cards (peanuts): See Marketing cards (tobacco), Peanut commodity card, and Smart cards (peanuts).

Marketing cards (tobacco): A card that identifies the farm, producer, and pounds available to sell. The marketing card is brought to the warehouse and presented prior to auction. Each sales invoice is imprinted with the card at the time the tobacco is weighed. The Farm Service Agency marks tobacco crop marketing cards when advancing loan funds or subordinating crop liens for the purpose of financing the production of the crops. See Marketing cards (peanuts).

Marketing certificates: Certificates that have been issued by the USDA as part of a price-support program. These may be redeemed for cash or commodities, depending on the specific provisions of the program. Such certificates may be generic or for a specific commodity. See Generic commodity certificate(s).

Marketing contract(s): Verbal or written agreements between a contractor and a producer establishing a price formula in advance of the product being delivered. Under marketing contracts, the contractee (producer) retains ownership of the product and has a large degree of decision-making control over the production process, but has a known market and price. The majority of marketing contracts involve fruit and vegetable production. See Contract farming, and Production contract(s).

Marketing loan gain(s) (MLG): Any portion of the interest and principal of a marketing assistance loan that does not have to be repaid because of market loan repayment provisions. The portion of a loan, if any, that is waived when a loan is repaid (at the posted county price oradjusted world price instead of the loan rate) is referred to as a marketing loan gain for the producer.

Marketing loan program: program first authorized by the Food Security Act of 1985 that allowed producers to repay nonrecourse loans at less than the announced loan rates whenever the world price for the commodity was less than the loan rate. Under the Food, Agriculture, Conservation, and Trade Act of 1990, marketing loan programs were mandatory for soybeans and other oilseeds, upland cotton, and rice, and discretionary for wheat and feed grains. For example, a rice producer could place a hundredweight of rice under loan and receive the nonrecourse loan rate of $6.50. If the world price, adjusted to the farm level, was less than $6.50 per hundredweight (i.e., $5.00), then the producer could satisfy the terms of the loan and regain clear title to the crop by repaying $5.00 to the Commodity Credit Corporation. Marketing loans protect producer returns while modifying the price-supporting function of the nonrecourse loan program, if such function should be a deterrent to exports. Marketing loan provisions under the new market loan repayment program were maintained in the Federal Agriculture Improvements and Reform Act of 1996 for wheat, feedgrains, soybeans, cotton, and rice, and in the Farm Security and Rural Investment Act of 2002 for covered commodities and peanuts, wool, mohair, honey, small chickpeas, lentils, and dry peas. See Adjusted world price (AWP), Marketing loan repayment (provision) (MLR), and Posted county price (PCP).

Marketing loan repayment (provision) (MLR): Under the Federal Agriculture Improvements and Reform Act of 1996, the provision available for loan-eligible commodities except extra-long staple cotton; the Farm Security and Rural Investment Act of 2002 maintained eligibility for covered commodities and extended coverage to peanuts, wool, mohair, honey, small chickpeas, lentils, and dry peas. Under certain circumstances, nonrecourse loans may be repaid by a producer at less than the principal, accrued interest, and other charges. Market loan repayment provisions are designed to prevent the forfeiture of loan collateral. To be eligible for the MLR, the nonrecourse loan must not have matured. Market loan repayment provisions are active when the applicable alternative loan repayment rate is less than the nonrecourse loan principal plus interest and other charges (and in the case of upland cotton, the per unit storage costs for a given outstanding loan). When using commodity certificates purchased from Farm Service Agency at the market price to repay a loan, the marketing loan gain does not count against the $75,000 per person payment limitation. Also Market loan repayment (provision) (MLR). See Actual loan repayment rate, Adjusted world price (AWP), Alternative (loan) repayment rate, Applicable alternative loan repayment rate, Nonrecourse loan(s), and Posted county price (PCP).

Marketing loan repayment rate: See Adjusted world market price (AWP), Marketing loan repayment (provision) (MLR), and Posted county price (PCP).

Marketing loan(s): loan that may be repaid at a level below the rate at which the nonrecourse loan was made. Under previous farm bills, marketing loans were mandatory for upland cotton and rice, and discretionary for wheat, feed grains, and soybeans.Marketing loan provisions were maintained in the Federal Agriculture Improvements and Reform Act of 1996 for wheat, feedgrains, soybeans, cotton, and rice, and in the Farm Security and Rural Investment Act of 2002 for covered commodities and peanuts, wool, mohair, honey, small chickpeas, lentils, and dry peas. See Marketing loan program, and Marketing loan repayment (provision) (MLR).

Marketing loss (assistance) payments: From 1998 until passage of the Farm Security and Rural Investment Act of 2002, Congress passed annual emergency farm legislation that allocated marketing loss assistance payments for program crops. The payments were paid using the same payment formula that was used for regular Agricultural Market Transition Act (AMTA) payments. Payments were first provided in the Omnibus Consolidated and Emergency Supplemental Appropriations Act, FY1999, and made to producers for marketing losses experienced in 1998. Producers eligible for 1998 production flexibility contract payments were issued the marketing loss assistance payments in proportion to the amount of production flexibility contracts received in FY1998. A separate person could not receive more than $19,888. Similar additional payments were made to holders of 1999 production flexibility contracts, under provisions of the Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act, 2000. Also, passage of the Agricultural Risk Protection Act of 2000 provided additional payments to holders of 2000 production flexibility contracts, at the same rate as was paid for the 2000 AMTA payments. See Dairy Market Loss Assistance Program (DMLA).

Marketing order(s): See Federal marketing order(s) and agreement(s).

Marketing Orders and Agreements: An account under Title I, Agricultural Programs, of agricultural appropriations. See Section 32.

Marketing quota(s): (1) Generally, quotas authorized by the Agricultural Adjustment Act of 1938 to regulate the marketing of some commodities when supplies are or could become excessive. A quota normally represents the quantity the USDA estimates to be required for domestic use, exports, and adequate carryover stocks during the year. Marketing quotas are binding upon all producers if two-thirds or more of the producers holding allotments for the production of a crop vote for quotas in a referendum. Marketing quotas are usually put into effect through acreage allotments or specific limits on marketing. Producers who plant more of a commodity than their farm acreage allotments or market more than their quota are subject to marketing penalties on the “excess,” and are ineligible for government price-support loans. Quota provisions have been suspended for wheat, feed grains, and upland cotton since the 1960s; rice quotas were abolished in 1981. Poundage quotas were used for domestically consumed peanuts, but not for exported peanuts, until the peanut price-support program was significantly altered with passage of the Farm Security and Rural Investment Act of 2002. Marketing quotas are also used for major types of tobacco. The Food, Agriculture, Conservation, and Trade Act of 1990 mandated marketing quotas for sugar and crystalline fructose when sugar imports for U.S. consumption are less than 1.25 million short tons (raw value). This authority was suspended in the Federal Agriculture Improvements and Reform Act of 1996. (2) A marketing quota sets the maximum amount of a commodity that a producer can sell without incurring a penalty. Used most consistently in policy for tobacco, this kind of mandatory quota usually requires some substantial majority approval vote by producers.

Marketing season: See Crop year(s).

Marketing Services: See Agricultural Marketing Service (AMS).

Marketing spread: The difference between the price the producer received for a commodity and the price paid by the consumer for an equivalent amount of the same commodity. This farm-retail spread includes charges for assembling, storing, processing, transporting, and distributing the products.

Marketing type (bargaining association): bargaining association whose principal identifying characteristic is that it takes title to the production of its members and negotiates the prices and terms of sale. Such a bargaining association may operate one or more pools, divert products to alternate uses, and average out returns to the members of the pool.

Marketing year(s): The 12-month period beginning around harvest time, during which a crop is harvested and marketed. The marketing year for wheat, barley, oats, canola, rapeseed, and flaxseed is from June 1 to May 31; for corn, grain sorghum, sunflower seed, safflower, mustard seed, and soybeans, September 1 to August 31; for cotton, peanuts, and rice, August 1 to July 31; for flue-cured tobacco, July 1 to June 30; and for burley tobacco, October 1 to September 30. See Crop year(s).

Marketwide pool(ing): All milk marketing orders operate marketwide pools for determining producer prices. Under marketwide pooling, the entire value of the milk used in all classes is divided by the total milk deliveries to determine the weighted average or blend price for the market. The blend price is the minimum price that must be paid to each producer under the order. The location at which the milk was received by the handler also affects the price. Thus, each producer shares proportionately in the returns produced by all milk uses in the market. Cooperatives may combine the proceeds of its members from different markets and pay a reblended price to members. This price may be different than the price received by individual producers.

Marking: Each inspected and passed animal carcass, half-carcass, or quarter-carcass must be identified by a federal mark of inspection or a state mark of inspection. A product with a state mark of inspection is limited to commerce within the state where it was inspected and marked. State-inspected product shall not be transported across state lines. Another type of mark is one for exotic animals that have been inspected and approved for human food. See Official inspection legend.

Maryland tobacco: A light, air-cured tobacco, similar to burley tobacco, used in cigarette blends.

Mast: Fruits and seed of shrubs, woody vines, trees, cacti, and other non-herbaceous vegetation, available for animal consumption.

Master Settlement Agreement (MSA): See Tobacco settlement.

Mastitis: A bacterial infection of a cow’s udders. See Somatic cell(s) (dairy), and Somatic cell count (SCC).

Material harm: In cases of unfair trade practices, a finding by the International Trade Commission that the injury or threat of injury caused to domestic industries in output, sales, imports, capacity utilization, profits, cash flow, employment, and wages is not inconsequential, immaterial, or unimportant.

Maturity; mature(d): (1) All nonrecourse loans for wheat, feed grain, rice, and oilseed crops shall be due, or mature upon demand by the Commodity Credit Corporation, and not later than the last day of the ninth calendar month following the month in which the security agreement for the loan was signed. Upland cotton and extra-long staple cotton loans previously matured in ten calendar months, beginning on the first day of the month in which the security agreement for the loan was signed, but theFarm Security and Rural Investment Act of 2002 (Sec. 1203) reduced the loan term to nine months. Peanut loans mature on April 30 following the year in which the peanuts were harvested. Sugar loans are for nine months, but all loans will mature by the end of the fiscal year in which the loans were made. However, under the Farm Security and Rural Investment Act of 2002 (Sec. 1401(d)(2), a supplemental loan may be made in the case of a loan first made within the last three months of the fiscal year. Loan collateral pledged on a loan cannot be forfeited to the CCC in lieu of repayment until after the loan maturity date. (2) An estimation of the chronological age of the animal or carcass by assessing the physiological stages of maturity of bone and muscle characteristics.

(3) Muscle tissue composed of protein, water, and fat. (4) The conversion of muscle through rigor mortis. (5) Under the Federal Meat Inspection Act, the part of the muscle of any cattle, sheep, swine, equine (horses or mules), or goats which is skeletal or which is found in the tongue, diaphrahm, heart, or esophagus, with or without the accompanying and overlying fat, and the portions of bone (in bone-in product such as T-bone or porterhouse steak), skin, sinew, nerve, and blood vessels which normally accompany the muscle tissue and that are separated from it in the process of dressing of the carcass. Under the FMIA, meat does not include the muscle found in the lips, snout, or ears. Also, meat may not include significant portions of bone, including hard bone and related components, such as bone marrow, or any amount of brain, trigeminal ganglia, spinal cord, or dorsal root ganglia.

Meat and poultry inspection: The Federal Meat Inspection Act of 1906 and the Poultry Products Inspection Act require all meat and poultry to be federally inspected. The Food Safety and Inspection Service is the USDA agency that inspects meat and poultry. More than 7,500 FSIS food inspectors and veterinarians carry out the inspection laws in some 6,200 privately owned meat and poultry plants around the country, ensuring that all domestically produced meat and poultry sold in interstate or foreign commerce is safe, wholesome, and accurately labeled. One or more federal inspectors are “on the line” during all hours a plant is operating. Meat and poultry sold only within a state may be inspected under an FSIS-approved state inspection program equal to the federal program. If a state is unable to operate its own inspection program, the FSIS assumes responsibility for this inspection. Inspections are chiefly in meat and poultry packing and processing plants. To ensure the wholesomeness of imported meat and poultry products, the FSIS reviews and monitors foreign inspection systems to ensure that they are equal to the U.S. system.

Meat broker: Under 12 U.S.C.§ 601, any person, firm, or corporation engaged in the business of buying or selling carcasses, parts of carcasses, meat, or meat food products of cattle, sheep, swine, goats, horses, mules, or other equines, on commission or otherwise negotiating purchases or sales of such articles other than for his own account or as an employee of another person, firm, or corporation.

Exemptions include sandwiches, pepperoni rolls, bagel dogs, cheese balls, bread containing small pieces of meat as flavoring, products containing less than three percent raw or two percent cooked meat, and products containing less than 30 percent fat as the only livestock ingredient. (3) Under 12 U.S.C. § 601, any product capable of use as human food that is made wholly or in part from any meat or other portion of the carcass of any cattle, sheep, swine, or goats (and including food products of equines), excepting products that contain meat or other portions of such carcasses only in a relatively small proportion or historically have not been considered by consumers as products of the meat food industry, and that are exempted from definition as a meat food product by the USDA.

Meat import law: A U.S. law, enacted in 1964 and amended in 1979, that provided for the imposition of import quotas if imports of certain meat products exceeded the trigger level. This limit was calculated from a formula based on domestic import quota meat production and cow-beef production. The law applied to fresh, chilled, and frozen meat of cattle, sheep (except lamb), and goats, as well as certain prepared and preserved beef and veal products.

Meat traceability: The comprehensive concept of tracking the movement of identifiable meat products through the marketing chain – from source animal, through growth and feeding, slaughter, processing, and distribution, to the point of sale or consumption (or backwards from the consumer to the source animal).

Mechanical harvester: (1) A machine that automatically strips the leaves from the tobacco stalk by rotating spiraled rubber wipers attached to a movable head. These machines are used primarily for harvesting flue-cured tobacco. (2) Specialized machinery used for harvesting tree fruit and nuts that shakes the fruit or nuts onto a catching frame. (3) Specialized machinery used for harvesting vegetables and root crops such as potatoes and beets. Root crops are harvested by machines that take the root out of the ground, clean it, and cut the top off the plant. (4) See Bale(d) hay, and Baling (hay). (5) See Combine(s). (6) See Picker; picker system; picker harvester (cotton), Pick(ed)(ing), and Stripper cotton; stripper system; stripper harvester.

Mechanical tenderization: The process of physically breaking up the muscle fiber structure. This can be achieved by needle or blade tenderizing. Needle tenderizing is the process of pressing several thick needles through the meat cut. As the needles pass through the muscle, they will break up the fiber structure. The use of a tenderizer machine is the most common method of tenderization currently used. See Chemical tenderization.

Mechanically separated meat: meat food product that is a paste-like and batter-like product produced by forcing bones with attached meat under high pressure through a sieve or similar device to separate the bone from the meat tissue. Unlike AMR systems in which bone and bone product are not pruposefully incorporated in the final meat product, MS systems are designed to purposefully incorporate significant amounts of bone and bone components in the resulting meat food products. The USDA will prohibit use of mechanically separated meat in human food.

Mechanically separated poultry: A paste-like and batter-like poultry product, produced by forcing bones, with attached edible tissue, through a sieve or similar device under high pressure to separate bone from the edible tissue. Mechanically separated poultry has been used inpoultry products since 1969.

Methanol: An alcohol that can be used as an alternative fuel or as a gasoline additive. It is less volatile than gasoline; when blended with gasoline, it lowers carbon monoxide emissions but increases hydrocarbon emissions. Used as pure fuel, its emissions are less ozone-forming than those from gasoline.

Methyl bromide: An odorless, colorless gas widely used as a broad spectrum fumigant to control insects, fungi, bacteria, and nematodes on harvested commodities, in buildings, and in agricultural soil. It is one of the five most-used pesticides in the U.S. Methyl bromide is believed to deplete the ozone layer, and production in the U.S. is to be banned by 2005. Under terms of the Montreal Protocol, adopted by the U.S. as part of the Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act, 1999, developed countries agreed to reduce consumption by 25 percent in 1999, 50 percent in 2001, 70 percent in 2003, and 100 percent in 2005 from 1991 consumption levels. Developing countries agreed to a 20 percent reduction by 2005 and a 100 percent reduction by 2015 from the average 1995-98 consumption levels. For many current uses, no alternative to methyl bromide exists. The Environmental Protection Agency adopted a final rule January 1, 2003, to provide methyl bromide users in the U.S. with an exemption to the phaseout of methyl bromide for quarantine applications and pre-shipment applications.

Methyl Bromide Transitions Program (MBT): CSREES Integrated Activities IPM program designed to support the discovery and implementation of practical pest management alternatives for commodities affected by the methyl bromide phase-out. The program focus is on short-term projects developing management technologies, integrated and systems approaches, and extension delivery programs for methyl bromide alternatives that support commodities at risk. These activities will involve basic research and applied research designed to deliver and demonstrate the practicality and economic feasibility of new technologies and will be conducted at research facilities, extension centers and grower demonstration plots. See Crops at Risk (CAR), IPM Section 406 Program; Integrated Activities; Integrated Research, Education, and Extension Competitive Grants Program; Organic Transitions (ORG); and Risk Avoidance and Mitigation Program (RAMP).

Milk marketing orders regulate handlers who sell milk and manufactured dairy products within an order region by requiring handlers to pay not less than the established minimum price for Grade A milk purchased from producers, depending on how the milk is used. The federal government may also support the prices of certain manufactured dairy products, such as butter and cheese, through purchase and storage programs. Federal milk marketing orders are permanently authorized and do not require periodic reauthorization. Milk marketing orders are not mandatory; producers must request an order and approve it through a referendum. The Federal Agriculture Improvements and Reform Act of 1996 (Sec. 143) required the reduction of the number of federal milk marketing orders to no more than 14 and no less than 10. The USDA consolidated the existing 31 milk marketing order areas into 11 milk marketing order areas. It also added some previously unregulated areas (counties) into the new milk marketing order areas. In further reforms, the USDA established four classes of milk use to be pooled under the new orders. Each class will have a skim milk price and a butterfat price calculated from the prices of dairy products. See California milk marketing order, and Minimum pricing (dairy).

Milk price-support program: See Dairy price-support program (DPSP).

Milk Production Termination Program: program, often called the Dairy Termination Program or the Whole-Herd Buyout Program, authorized by the Food Security Act of 1985. The program was designed to reduce milk production. Producers whose bids were accepted by the USDA agreed to slaughter or export all female dairy cattle, have no interest in milk production or dairy cattle for five years, and not use their facilities for those purposes during that time. The program was in effect from April 1, 1986, through September 30, 1987. During that period, 1.6 million dairy cows were removed from production. The Food, Agriculture, Conservation, and Trade Act of 1990 included a specific provision prohibiting the adoption of such a program.

Minimum price contracts: Grain marketing contracts that allow producers to insure a minimum price for commodities to be delivered in the future but with a feature to allow the producer to receive additional money if the market should rise. The buyer uses commodity options to protect against a possible price rise in the future.

Minimum pricing (dairy): Each milk marketing order sets minimum prices for the various use-classes. Federal milk marketing orders now use product-based pricing. The market value of cheese, butter, whey, and nonfat powder are used to calculate a minimum value for the producers’ milk used to make those products. Such prices are established for milk of 3.5 percent butterfat content, and adjustments are made for milk that has a butterfat test different from that specified. Some orders also adjust for the solids-not-fat or protein content of the milk. Since some milk marketing order areas get milk from wide geographic areas, prices also are adjusted to reflect values at different locations. The orders provide that producers be paid a uniform or average price. In most orders, this uniform price is calculated by combining and averaging class values for all handlers through market wide pooling provisions. See Equalization pool.
