Mechanically separated meat (MSM), also known as mechanically recovered/reclaimed meat (MRM), is a paste-like meat product produced by forcing beef, pork, or chicken bones, with attached edible meat, under high pressure through a sieve or similar device to separate the bone from the edible meat tissue. Mechanically separated meat has been used in certain meat and meat products since the late 1960s. This product can be contrasted with meat extracted by advanced meat recovery systems. The most common use of MSM is into hotdogs.

this also in bologna, and other meats that are not completely as a certain type of meat like chicken, turkey or ham.
