An E. coli outbreak in the Edmonton area that has resulted in the death of one person is linked to pork products sold by a central Alberta Hutterite colony, Alberta Health Services said Wednesday.

The Canadian Food Inspection Agency has issued a food recall warning for certain pork products sold and distributed by The Meat Shop at Pine Haven between Feb. 19 and April 24. The range of products includes ground pork, chops and roasts as well as bacon, wieners and organ meats.

The Pine Haven Hutterite colony is 12 kilometres southeast of Wetaskiwin.

Meat Shop temporarily closed

The manager of The Meat Shop told CBC that he feels terrible about the outbreak.

"We're more concerned about this than anybody," Tim Hofer said on Wednesday.

The Meat Shop performed a thorough cleaning of all surfaces, he said, and has been reviewing its procedures since shutting down on April 18.

"As soon as we were made aware of a potential problem, we jumped on it and shut processes down."

Hofer said the shop has never had an issue with contamination in the past.

Families from the Pine Haven colony also ate meat from the shop, he said, and didn't get sick.

"Our business is our livelihood," Hofer said. "The community itself, there's 23 families within the community, they eat from the Meat Shop. There were no flags for us at all."

36 confirmed cases

The number of lab-confirmed cases of E. coli O157:H7 linked to the outbreak is now at 36, including 11 patients who have needed hospital care and one who died "likely due to infection with E. coli," AHS said in a news release.

An AHS investigation has found a common link between the lab-confirmed cases and certain raw and ready-to-eat pork products sold and distributed by the business.

All 36 cases reported so far have been linked to pork sold by the shop, Dr. Jasmine Hasselback, AHS medical officer of health for the Edmonton zone, said at a news conference Wednesday afternoon.

"There has been great co-operation by The Meat Shop at Pine Haven," Hasselback said. "They have held all potentially contaminated products. So we know that that is not entering any further into public consumption."

AHS had previously warned that anyone who had eaten at a south Edmonton restaurant called Mama Nita's Binalot since March 15 should monitor themselves for symptoms of the infection. Several cases of E. coli infection had been linked to food served at the restaurant.

Those cases are also linked to the pork products, Hasselback said.

Three lines of investigation

Tracking down the source of the outbreak involved three principal lines of investigation, she said.

Laboratory tests confirmed that the cases were linked. Officials questioned people who became ill, asking them what and where they ate. The CFIA and Alberta Agriculture then gathered food samples to be tested.

"With all those three, you can start making some linkages," Hasselback said. "And it was through that that we were able to work backwards and identify this site."

AHS and the CFIA are encouraging consumers to check if they have recalled products in their homes. Businesses should also verify whether they have any recalled products.

Recalled products should be thrown out or returned to the store where they were purchased. Food contaminated with E. coli O157:H7 may not look or smell spoiled but can still make people sick if eaten.
