Winnipeg health authorities said that meat contaminated with E. coli had been traced to the Dutch Meat Market in St. Boniface, where restaurants purchased meat.

While the Dutch Meat Market and several burger restaurants that purchased their meat from the butcher have now been given a clean bill of health from authorities, George’s Burgers and Subs did not pass a second inspection. George’s Burgers and Subs on Henderson Highway in Winnipeg has been closed as a result.

A lawyer for the Dutch Meat Market said Monday the business is considering legal action against the farm or slaughterhouse that supplied it with the contaminated meat.

Health officials are still trying to track down the original source of the meat, said Dr. Pierre Plourde, medical officer for the Winnipeg Regional Health Authority, on Tuesday.

More than 35 people have contacted health authorities with samples of meat they bought at Dutch Meat Market in the first two weeks of August, which will be tested in an effort to track down the original source.

The August outbreak raised the total number of E. coli infections this summer to 57. In all, there were 65 cases so far this year. Last year, the WRHA recorded only 13 cases of E. coli infection, and 25 cases in 2004.
