Meat product

'Meat product' means any food which consists of meat, or which contains meat, mechanically recovered meat, from an animal or bird, heart, tongue, head muscles (other than cheeks), carpus, tarsus (feet) or tail.

The following are not meat products: raw meat with no added ingredients (except proteolytic enzymes). uncooked poultry with no added ingredients except additives, water, self-basting preparations or seasonings. products containing fat but no other meat.

Meat

'Meat' means skeletal muscle with naturally included or attached fat and connective tissue. Note that this means mechanically recovered meat, heart, tongue, etc are not meat for the purposes of calculating meat contents. There are also limits set for the amount of fat and connective tissue that can be included with the muscle as 'meat'.

This means, for example, that if minced ox heart and fat are the sole ingredients in a product then the meat content will be zero!
