New Brunswick health officials say E. coli source no longer in food supply

FREDERICTON - Health officials in New Brunswick say they believe the source of a recent E. coli outbreak has passed through the food supply chain and is no longer a risk to the public.

There have been 13 confirmed cases of people with E. coli O157, the same strain found during the Walkerton, Ont., water tragedy in 2000 that killed seven people.

More than 30 people reported cases of bloody diarrhea, which is a common symptom of E. coli infection.

A total of 14 people were hospitalized during the outbreak, but none developed serious complications.

Dr. Eilish Cleary, New Brunswick's chief medical officer of health, says the majority of confirmed cases ate at Jungle Jim's restaurant in Miramichi in the days prior to becoming ill.

She says food samples taken from the restaurant have tested negative, but it's likely the contaminated food source has been all used.

Cleary says the restaurant has co-operated fully with public health officials, including a thorough sanitation of the kitchen and completion of a food safety course.

She says no new cases have been reported, suggesting that the source of the contamination remained in the food supply chain for only a short period of time.
