Mechanically Separated Turkey Water

Mechanically separated turkey (MST) is a paste-like and/or foamy poultry product, produced by removing bones from poultry carcasses through a mechanical process. The resulting material is then further processed, often with water, to create a finer texture. This process is used to utilize parts of the turkey that might otherwise be discarded.

Manufacturers add mechanically separated turkey water to processed meat products to improve texture, moisture, and yield. It is commonly found in items like sausages, hot dogs, frozen breakfast sandwiches, and some frozen dinners. Its inclusion helps bind ingredients and maintain a desirable mouthfeel in these foods.

Mechanically separated turkey is permitted for use in processed poultry products by the FDA. It is not a GRAS substance but is allowed as part of the finished product. The FDA has specific standards for its production and use in poultry products. There are no widely reported health concerns associated with its consumption at typical levels found in processed foods. JECFA and EFSA have not specifically evaluated this ingredient in isolation, but rather as part of finished food products.
