finds E. coli in dough doesn’t
match outbreak strain

7/14/2009-On July 9, the
Food and Drug Administration (FDA) said the strain of E. coli found in a
sample of raw cookie dough collected at a Nestlé USA manufacturing plant
does not match the strain that has been linked to a 30-state outbreak, and
they aren't sure how the dough was contaminated, according to the Associated Press. The
FDA and the Centers for Disease Control and Prevention (CDC) have been
investigating whether the cookie dough was the source of the E. coli outbreak,
which has sickened at least 69 people in about 30 states.
In June, Nestlé
voluntarily recalled all Toll House refrigerated cookie dough products made
at its Danville, Va., factory after the FDA told Nestlé it suspected
consumers may have been exposed to E.
coli bacteria after eating the dough raw. On June 29, the FDA
confirmed evidence of E.
coli O157:H7 in a retained production sample of 16.5 oz Nestle
Toll House refrigerated chocolate chip cookie dough bar. But on July 9, FDA
spokesman Mike Herndon said tests on the dough, which came from an unopened
package, show the strains of E.
coli don't match the E.
coli strain linked to the outbreak. That could mean the dough
may have been contaminated with multiple strains. But neither the FDA nor
Nestlé has discovered a probable source.
The FDA is working with
Nestlé on the investigation, which Herndon said was ongoing. According to
the FDA report (Form 483), federal investigators did not find any E. coli in the
Danville plant. As part of the inspection, and through additional
independent testing, more than 1,000 tests were performed at the Danville
facility, including extensive environmental sampling and analyses. Nestlé
also dismantled its production lines for thorough inspection, conducted
extensive testing on equipment and ingredients, and has carefully reviewed
its quality and food safety procedures. To validate these procedures, a
controlled production is being phased-in on a few production lines.
Scientists from the FDA, CDC, and the United States Department of
Agriculture have been working along with nine Nestlé microbiologists on
this comprehensive investigation.
