. Examples are fat, flesh, blood, milk, eggs, and lesser known products, such as isinglass and rennet. Animal by-products, as defined by the USDA, are products harvested or manufactured from livestock other than muscle meat. In the EU, animal by-products (ABPs) are defined somewhat more broadly, as materials from animals that people do not consume. Thus, chicken eggs for human consumption are considered by-products in the US but not France; whereas eggs destined for animal feed are classified as animal by-products in both countries. This does not in itself reflect on the condition, safety, or wholesomeness of the product. 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. 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

Products sourced from humans (ex; hair sold for wigs, donated blood) are not typically classified as animal products even though humans are part of the animal kingdom. Several popular diet patterns prohibit the inclusion of some categories of animal products and may also limit the conditions of when other animal products may be permitted. This includes but not limited to secular diets; like,

By-products in pet food

The leftover pieces that come from the process of stripping meat from animals tends to get used for different purposes. One of them is to put these parts into pet food. Many large, well-known pet food brands use animal by-products as protein sources in their recipes. This can include animal feet, livers, lungs, heads, spleens, etc or an admixture in the form of

meat and bone meal Meat and bone meal (MBM) is a product of the rendering industry. It is typically about 48–52% protein, 33–35% ash, 8–12% fat, and 4–7% water. It is primarily used in the formulation of animal feed to improve the amino acid profile of t ...
