Mechanically separated chicken
One of the editors at the Sun stopped by my desk this afternoon and said she had been shopping for hot dogs, and every brand she picked up had this ingredient: "mechanically separated chicken [or turkey]." She finally found one kind of hot dog that didn't and bought it.
I hadn't heard the phrase, but then it's been awhile since I bought hot dogs, so I Googled it. The first listing was this.
Twilight Zone music, please. ...
Here's what the link gave as a definition, although I couldn't find the original source immediately.
Mechanically Separated Poultry is a paste-like poultry product produced by forcing crushed bone and tissue through a sieve or similar device to separate bone from tissue. Mechanically separated poultry has been used in poultry products since 1969 after the National Academy of Sciences found it safe for use. In 1995 the final rule on mechanically separated poultry said it was safe to use without restrictions. However, it must be labeled as "mechanically separated chicken or turkey" in the ingredient statement. The final rule became effective Nov. 1996.
