According to Canadian News reports over the last 24 hours:

“While officials believe the bacteria likely came from fresh produce – most likely lettuce – the food inspection agency said there’s little hope it will be able to determine the source of the outbreak…. Two separate E. coli outbreaks in Ontario, with a total of 34 confirmed and suspected cases, may have been the result of tainted lettuce.”

Remember, most E. coli O157:H7 outbreaks in the last few years have been linked to LETTUCE consumption.  In fact, in a letter written to the spinach and lettuce industry last year, Robert E. Brackett, Ph.D.. Director Center for Food Safety and Applied Nutrition warned that the “FDA is aware of 18 outbreaks of foodborne illness since 1995 caused by Escherichia coli O157:H7 for which fresh or fresh-cut lettuce was implicated as the outbreak vehicle. In one additional case, fresh-cut spinach was implicated. These 19 outbreaks account for approximately 409 reported cases of illness and two deaths. Although tracebacks to growers were not completed in all 19 outbreak investigations, completed traceback investigations of eight of the outbreaks associated with lettuce and spinach, including the most recent lettuce outbreak in Minnesota, were traced back to Salinas, California.  See full letter at:
