E. coli in Flour and Cookie Dough Addressed at Food Protection Conference
At this year’s annual meeting of the International Association for Food Protection (IAFP) in Anaheim, California, several presentations address the issue of E. coli contamination in refrigerated cookie dough and the flour used to make it.
One presentation, “Flour Food Safety: The Changing Landscape — Escherichia coli O157:H7,” was given by representatives from Cargill, Nestle and ConAgra and outlined how the industry is reexamining flour as a potential source for E. coli contamination in food. The importance of this issue is highlighted by last year’s E. coli outbreak associated with Nestle Tollhouse raw cookie dough that sickened roughly 75 people in multiple states. According to and IAFP summary of the presentation:
“Flour has been viewed as a raw agricultural product for years; but with a recent outbreak involving consumption of an uncooked product containing flour, regulators and industry are re-examining whether flour should be treated as a RTE ingredient in some foods that may be consumed uncooked by the consumer. This mini-symposium will examine the history of flour and what industry knows about the microbiology of this product during production, harvesting and milling; the regulatory perceptions of flour as a potential vehicle of pathogens; the transformation of microbiological criteria associated with flour and the verification testing required to gauge compliance with the new criteria; and one solution available to deliver RTE flour as an ingredient.”
Another piece of research included at the conference comes from researchers at the Silliker, Inc., Food Science Center in South Holland, Illinois, and focuses on validating testing methodologies for raw cookie dough and its ingredients.
