An animal product is any material derived from the body of an animal. Examples are fat, flesh, blood, milk, eggs, and lesser known products, such as isinglass and rennet.〔Unklesbay, Nan. ''World Food and You''. Routledge, 1992, p. 179ff.〕 Animal by-products are carcasses and parts of carcasses from slaughterhouses, animal shelters, zoos and veterinarians, and products of animal origin not intended for human consumption, including catering waste (all waste food from restaurants, catering facilities, central kitchens, slaughterhouses and household kitchens). These products may go through a process known as "rendering" to be made into human and non-human foodstuffs, fats, and other material that can be sold to make commercial products such as cosmetics, paint, cleaners, polishes, glue, soap and ink. The sale of animal by-products allows the meat industry to compete economically with industries selling sources of vegetable protein.〔Ockerman, Herbert and Hansen, Conly L. ''Animal by-product processing & utilization''. Technomic Publishing Company Inc., 2000, p. 1.〕 Generally, products made from fossilized or decomposed animals, such as petroleum formed from the ancient remains of marine animals, are not considered animal products. Crops grown in soil fertilized with animal remains are rarely characterized as animal products. Several diets prohibit the inclusion of some animal products, including vegetarian, kosher, and halaal. Other diets, such as veganism and the raw vegan diet, exclude any material of animal origin.〔Stepaniak, Joanne. ''Being Vegan: Living with Conscience, Conviction, and Compassion''. McGraw-Hill Professional, 2000, p. 7.〕 ==Slaughterhouse waste== Slaughterhouse waste is defined as animal body parts cut off in the preparation of carcasses for use as food. This waste can come from several sources, including slaughterhouses, restaurants, stores and farms. In the UK, slaughterhouse waste is classed as category 3 risk waste in the Animal By-Products Regulations, with the exception of condemned meat which is classed as category 2 risk. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Animal product」の詳細全文を読む スポンサード リンク
