The Food Safety and Inspection Service (FSIS)
has announced changes to its procedures for Salmonella
verification sampling program of raw beef products and requested comments on
the new rule.
According to the Federal Register notice, available here,
FSIS will begin analyzing all raw beef samples that it collects for Shiga
toxin-producing Escherichia coli
(STEC) analysis for Salmonella as
well. To be consistent with the Agency’s
STEC analytic sample portions, FSIS laboratories will increase the raw ground
beef analytic sample portion from 25 grams to 325 grams for the Salmonella analysis. These changes will “likely improve FSIS’s
ability to detect Salmonella by
increasing the sample portion for Salmonella
analysis and increasing the number of establishments being sampled at any given
time.” After collecting “at least three
months of data” with the new sampling and testing procedures, FSIS plans to
develop and revise Salmonella
performance standards for the new sample sets.
Sam Robinson of the Midwest Center for InvestigativeReporting, reported on the problem of Salmonella
in beef in an article as part of a “Cracks in the System” series, available here. Robinson reports that scientists have
“realized they may have misidentified the source of Salmonella in beef cattle.
They now realize it may be in the lymphatic system of cattle, making it
harder to prevent than E. coli.”
James
Mardsen, professor of animal science at Kansas State University and writer for
the blog, meatingplace.com,
says that Salmonella is the biggest
challenge facing the beef industry.
Mardsen noted that incidences of E.
coli “have dropped sharply over the past 10 years, but Salmonella isn’t dropping, which is perplexing.” In addition, “some
strains of Salmonella that have been
observed in beef are drug resistant strains, so they pose a public health
problem.”
