Mechanically separated poultry (i.e., chicken, turkey) is a paste-like and batter-like product produced by forcing the bones and attached edible tissue through a sieve or similar device to separate the bone from the edible poultry tissue. This product is intended for use in the formulation of other poultry products. During this process, it is possible for bones to be crushed or pulverized, resulting in a limited amount of bone particles. Because it may contain some bone particles, any product that has been produced using the mechanical separation process cannot, by definition, be labelled as "poultry." Instead, it must be labelled appropriately as "mechanically separated chicken" (or turkey) on the product's label. Mechanically separated chicken and turkey are used in products such as chicken and turkey franks, bologna, nuggets, and patties.
