Meat from mammals and poultry used as a food ingredient, merging USDA's separate Beef, Pork and Poultry groups into one subcategory because Poultry alone would otherwise be a single-member Chicken-only group. Belongs here: Beef, Chicken, Lamb, Pork. Does not belong here: a fish or shellfish ingredient, grouped under finfish and shellfish products, or a finished meat dish, which is a dish entity.
