FSIS Salmonella laboratory method extended to 325 g sample for raw beef product

USDA's Food Safety and Inspection Service (FSIS) laboratories have validated a 325 gram analytical portion option for Salmonella analysis of raw beef. The Microbiology Laboratory Guidebook (MLG) method chapters and associated method flow chart will be posted to the MLG. The agency will begin using the method May 1, 2013.

In an update published late last week, the agency corrected a March 29 alert about the new methodology.  According to agency's April 5 Constituent Update, FSIS will not use the method for raw ground beef at least until this intention is published in the Federal Register and the agency has had an opportunity to consider any comments that it receives on this planned action.
