Cultured meat

PVDE is a nontoxic resin and may be safely used in articles intended for repeated contact with food (190). Based on studies under controked conditions, including acute oral, systemic, subchronic, and subacute contact implantation and tissue culture tests, no adverse toxicological or biological response has been found in test animals (191,192). PVDE is acceptable for use in processing and storage areas in contact with meat or poultry products prepared under federal inspection and it complies with the 3-A sanitary standards for dairy equipment. 

Cells of microorganisms have constituted a portion of human food siace ancient times. Yeast-leavened baked products contain the residual nutrients from the yeast cells destroyed duriag bakiag (see Bakery processes and leavening agents). Cultured dairy products, such as yogurt, buttermilk, and sour cream, contain up to lO cells of lactic acid bacteria per gram (19) (see Milk and milkproducts). Other examples of fermented foods consumed siace early times iaclude fermented meats, fish, and soybean products. 

In a departure from his usual and highly popular westerns, author Louis L Amour wrote a novel in 1987, Best of the Breed (Bantam Press), in which a military pilot of native American ancestry is shot down over the former Soviet Union and is forced to use the survival skills of his ancestral culture to escape his enemies. On the rare occasions when he is able to trap and kill an animal for food, he selectively eats the fat, not the meat. Based on your reading of this chapter, what is his reasoning for doing so ... 

Fe" (2 ppm), casein hydrolyzate (0.2 g/dl), yeast extract (0.2 g/dl), corn steep liquor (0.2 ml/dl), polypeptone (0.1 g/dl), meat extract (0.1 g/dl) and sodium ribonucleate (10 mg/dl) were poured into respective test tubes and each tube was sterilized at 115°C for 10 minutes. Thereafter separately sterilized calcium carbonate was added in the amount of 2 g/dl and then cells of Bacillus subtUis S26910 were Inoculated into the above media and cultured with shaking at 30°C for 20 hours. 

As described in U.S. Patent 2,931,798, Streptomyces kanamyceticus (K2-J) was first cultured in shake flasks in the following media (a) 0.75% meat extract, 0.75% peptone,... 

Evidence suggests that HIV in humans is the result of cross-species transmission from primates infected with simian immunodeficiency virus (SIV). HIV-2 is closely related to the SIV found in sooty mangabeys in West Africa, and HIV-1 is similar to the SIV found in chimpanzees. The earliest known human HIV infection was in central Africa in 1959. Cultural practices such as the preparation and eating of bush-meat, or keeping primates as pets, may have allowed the virus to transmit from animal to human. The rapid spread of the virus throughout the world can be primarily attributed to high mobility due to modern transportation, sexual promiscuity, and drug abuse. 

Conventional livestock production systems can be very diverse and this diversity is influenced by economic, geographic, environmental and cultural factors. Conventional inputs for direct use in ruminant production include many types of plant feeds (i.e. forages, cereals, soybeans, etc.), industrial by-products (i.e. molasses, distiller s dried grain, meat bone meal, etc.), feed... 

The hygienic quality of the raw material used for the manufacture of sausage is an important factor relating to the production of biogenic amines. High-quality meats with low initial bacterial counts help keep the biogenic amines well below the toxic level (Shalaby 1995 Bover-Cid et al., 2000) and should be used with the addition of a non-amine-producing starter culture.

A main finding was the detection in retail poultry of . jejuni cultured in 192 of 862 specimens examined, as compared with 30 for Salmonella. Other types of retail meat had negligible contamination by either bacterium. Similarly, 48% of the jejuni enteritis cases were estimated to originate in poultry and none in beef or pork. Only a few of the cases were hospitalized. There were no deaths. 

The use of proteases for modification of protein functionality is an ancient art. Originally, the enzymes were either endogenous to the food (e.g., aging of meat) or part of an added bio-system (e.g. microbial cultures in cheeses) (3). With increased knowledge of what enzymes are and how they work, their delibrate isolation and addition to food systems became widely practiced. 

In Canada, routine monitoring of drug residues in edible animal tissues is an integral part of the Canadian federal meat inspection system of the Food Production and Inspection Branch, Federal Department of Agriculture and AgriFood. Monitoring for antibiotic residues in cultured fish is the responsibility of the Inspection Service Branch, Federal Department of Fisheries and Oceans.
