Mechanically separated meat

Mechanically separated meat (MSM), mechanically recovered/reclaimed meat (MRM), or mechanically deboned meat (MDM) is a paste-like meat product produced by forcing pureed or ground beef, pork, mutton, turkey or chicken under high pressure through a sieve or similar device to separate the bone from the edible meat tissue. When poultry is used, it is sometimes called white slime as an analog to meat-additive pink slime and to meat extracted by advanced meat recovery systems, both of which are different processes.
