Inside the meat plants; work of USDA inspectors." Reupload of a previously uploaded film with improved video & sound. Public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ http://en.wikipedia.org/wiki/Beef#USDA_beef_grades ...In the United States, the USDA Agricultural Marketing Service (AMS) operates a voluntary beef grading program. The meat processor pays for a trained AMS meat grader to grade whole carcasses at the abattoir. Users are required to comply with Food Safety and Inspection Service (FSIS) grade labeling procedures. The official USDA grade designation can appear in one or any combination of the following ways: container markings, individual bags, legible roller brand appearing on the meat itself, or by a USDA shield stamp that incorporates the quality and/or yield grade. There are eight beef quality grades. The grades are based on two main criteria: the degree of marbling (intramuscular fat) in the beef, and the maturity (estimated age of the animal at slaughter). Some meat scientists object to the current scheme of USDA grading since it is not based on direct measurement of tenderness, although marbling and maturity are indicators of tenderness. Most other countries' beef grading systems mirror the US model. Most beef offered for sale in supermarkets is graded US Choice or Select. US Prime beef is sold to hotels and upscale restaurants. Beef that would rate as US Standard or less is almost never offered for grading. - U.S. Prime - Highest in quality and intramuscular fat, limited supply. Currently, about 2.9% of carcasses grade as Prime. - U.S. Choice - High quality, widely available in foodservice industry and retail markets. Choice carcasses are 53.7% of the fed cattle total. The difference between Choice and Prime is largely due to the fat content in the beef. Prime typically has a higher fat content (more and well distributed intramuscular "marbling") than Choice. - U.S. Select (formerly Good) - lowest grade commonly sold at retail, acceptable quality, but is less juicy and tender due to leanness. - U.S. Standard - Lower quality, yet economical, lacking marbling. - U.S. Commercial - Low quality, lacking tenderness, produced from older animals. - U.S. Utility - U.S. Cutter - U.S. Canner Utility, Cutter, and Canner grade are rarely used in foodservice operations and primarily used by processors and canners. There are five beef yield grades - 1 to 5, which estimate the yield of saleable product, with YG 1 having the highest and YG 5 the lowest. Although consumers rarely see or are aware of it, yield grade was an important marketing tool for packers and retailers. The conversion from carcass and bone-in primals to boneless, trimmed cuts has reduced the importance. Traditionally, beef sold in steakhouses and supermarkets has been advertised by its USDA grade; however, many restaurants and retailers have recently begun advertising beef on the strength of brand names and the reputation of a specific breed of cattle, such as black Angus....
