The Food and Drug Administration (FDA) has reportedly confirmed the presence of Listeria monocytogenes at a San Antonio, Texas, processing plant implicated in four deaths. According to a November 3, 2010, FDA press release, the agency’s inspection of SanGar Fresh Cut Produce identified the bacteria “in processed celery and in multiple locations in the plant environment, including on food contact surfaces.”

FDA also noted that its samples matched “the DNA fingerprint of the clinical cases of listeriosis reported by the Texas Department of State Health Services [DSHS],” which last month closed the plant and ordered a recall of all products shipped since January 2010. “It comes as no surprise to us,” one DSHS spokesperson was quoted as saying. “If there was any doubt out there, this erases it. It’s another layer of confirmation that this plant had serious issues.” Additional details about the outbreak and recall appear in Issue 369 of this Update. See The Associated Press, November 3, 2010.
