Frankfurter Ingredients: Mechanically Separated Chicken

Mechanically separated chicken (MSC) is a paste-like poultry product made from chicken carcasses after the valuable meat has been cut away. Bones, skin, and remaining flesh are forced through a sieve or other device to create a slurry that is then used as an ingredient.

MSC is often used as a lower-cost filler in processed meat products like hot dogs, sausages, and chicken nuggets. Its texture and binding properties help create a uniform product.

In the US, MSC is permitted as an ingredient in certain poultry products. The FDA has evaluated its safety and allows its use under specific conditions. While generally considered safe by regulatory bodies when used as intended, some consumer groups have raised concerns about its processing method and nutritional profile compared to whole muscle meat.
