8 History of The Meat Industry Early butchers began killing and cutting animals for other people outside of their own familyMeat preservation began with the packing of meat in a salt solution in wooden barrels
9 History of The Meat Industry Animals were driven “on the hoof” until refrigeration was inventedHuge meat packing plants developed in the Midwest and began processing meat and shipping it
10 History of The Meat Industry As cities grew, small meat shops began to open to the publicAnimals were driven to the railroad “on the hoof” and taken to larger cities to be butchered
11 History of The Meat Industry Meat plants were rebuilt and/or automatedIt became more economical to ship frozen meat products than the live animal
12 Overview of the Beef Industry Approximately 1.3 billion total cattle in the world35 million of these are beef cows in the U.S.

16 Meat InspectionThe mandatory evaluation of the health status of meat animals and the wholesomeness of the meat obtained from them
17 Government surveillance: Purposes of inspection:Prevents harmful additives and ingredientsExcludes sick and diseased animalsEliminates misleading labeling and packagingProhibits contaminated and unwholesome meatsFederal meat inspection is administered by the Food Safety and Inspection Service (FSIS) as part of USDA.States may inspect meat only for use within that state.
18 Federal InspectionExceptions to federal inspection of meat to be sold are farmers and custom/local butchers, however, they fall under state inspection guidelines
19 CutabilityThe amount of saleable retail cuts that can be obtained from a carcass
20 Dressing Percentage (Hot carcass weight/live weight)X100 average=62.5% Ratio of the dressed carcass weight to the weight of the live animal(Hot carcass weight/live weight)X100average=62.5%
21 Wholesome Meat Act of 1967All meat must be inspected before sale
22 Humane Slaughter ActAll animals must be immobilized prior to shackling and bleeding
23 Slaughtering practices: Humane Slaughter Act (1960) requires animals to be rendered completely unconscious before slaughter.Carcasses are chilled for 24 to 48 hours before grading and processing.Brains, kidneys, tail, sweetbreads, and the tongue are by-products.Sold separately as “offal”Important source of incomeUSDA photo
24 ImmobilizationRendering an animal unconscious (brain dead), but the heart is still beating---technically the animal is still alive
25 Methods of Immobilization Mechanical (gun, steel rod gun, captive bolt gun)Electrical shockChemical (carbon dioxide)
26 KillingThe bleeding of an animal until the heart stops beating (Exsanguination)
27 Kosher SlaughteringButchering according to religious beliefs (Jewish Religion)Kosher is exempt from the Humane Slaughter Act (Immobilization)
36 Grading is voluntary …Establishes and maintains uniform trading standardsAids in setting the value of various cuts of meatCarcasses are graded by quality and yield.Quality grades for beef: prime, choice, select, standard, commercial, utility, cutter and cannerYield: proportion of usable meat to bone and fatMicrosoft photo

54 Recalled Beef Sold in Mass. Whole Foods June 12, 2014 – Boston.com
55 The US Department of Agriculture says that Fruitland American Meat, a Jackson, Mo. beef company, is recalling more than 4,000 pounds of beef due to a potential risk for Bovine Spongiform Encephalopathy (BSE), also referred to as mad cow disease.Not all beef is at risk. The bone-in “Rain Crow Ranch Ribeye” and quartered beef carcasses bearing establishment number EST inside the USDA mark of inspection are currently being recalled.
56 Thursday morning the USDA announced that a Whole Foods distribution center in Connecticut that serves stores in New England received the potentially tainted beef.Not all beef is at risk. The bone-in “Rain Crow Ranch Ribeye” and quartered beef carcasses bearing establishment number EST inside the USDA mark of inspection are currently being recalled.
57 These are branches of the cow’s central nervous system along the spine These are branches of the cow’s central nervous system along the spine. If the cow was infected with BSE, this is the area where the infected tissues would be located. Regulations require that they be removed from cattle more than 30 months old. It appears that procedure was not followed for the beef in question.The USDA has classified this recall as a low health risk, but a Class II recall: “This is a health hazard situation where there is a remote probability of adverse health consequences from the use of the product,” -USDAThe bone-in ribeyes roasts, according to the USDA, were distributed to two restaurants:

70 Grass Feed“Grass-fed. Grass-fed animals receive a majority of their nutrients from grass throughout their life, while organic animals’ pasture diet may be supplemented with grain. Also USDA regulated, the grass-fed label does not limit the use of antibiotics, hormones, or pesticides. Meat products may be labeled as grass-fed organic.”-AMS
71 Organic“Organic is a labeling term that indicates that the food or other agricultural product has been produced through approved methods. These methods integrate cultural, biological, and mechanical practices that foster cycling of resources, promote ecological balance, and conserve biodiversity. Synthetic fertilizers, sewage sludge, irradiation, and genetic engineering may not be used.”
72 NaturalAs required by USDA, meat, poultry, and egg products labeled as “natural” must be minimally processed and contain no artificial ingredients. However, the natural label does not include any standards regarding farm practices and only applies to processing of meat and egg products. There are no standards or regulations for the labeling of natural food products if they do not contain meat or eggs.

95 Types of Meat Storage Dehydration The nearly complete removal of water from foods under controlled conditionsThe removal of water decreases spoilage and bulkiness and increases the convenience of the food
96 Types of Meat Storage Vacuum Packaging Storing food by compressing all of the air out of the food sourceTends to make the meat look purple, which may turn consumers off
97 Types of Meat Storage Controlled Atmosphere Packaging Similar to vacuum packaging, but tries to control the gasses inside the meat package so bright red color remains
98 Types of Meat Storage Irradiation Uses different kinds of radiant energy to destroy living organisms that would normally spoil foodTakes the place of chemicals being applied to the foodNo radiation is left in or on the food!
99 Meat PackagingThe goal of meat packaging is to keep the meat fresh and decrease the chance of spoilage, change in color, or leaking of water/juices while still making it appealing to the consumer
