Gretchen Goetz of Food Safety News reports that fresh produce is now suspected to be the source of an E. coli outbreak that has sickened at least 15 people (as many as 20) in northeastern Canada, said a top health official Wednesday.  There are currently 10 (5 of those pending genetic testing) confirmed cases of E. coli 0157 in Nova Scotia, 6 in New Brunswick and 4 in Ontario.

“Our environmental and epidemiological investigations suggest a common source related to a produce item,” said Dr. Frank Atherton, deputy chief medical officer of health for Nova Scotia in an emailed statement.

While produce has been suspected, Atherton said investigators have yet to pinpoint a specific food.

“At this time, it is still too early to identify a definitive source, and with multiple provinces involved, additional coordination through our federal agencies is also required as part of the overall investigation.”
