The Public Health Agency of Canada says ten people have now fallen ill because of tainted beef from the XL Foods plant in Brooks, Alberta.

The agency recently confirmed five new cases, including another three on top of four already known in Alberta.

The agency says the individuals became ill more than two weeks ago, and they have now recovered or are recovering.

There are also two confirmed cases in Quebec and one in Newfoundland.

Tests are currently being done to find the source of E. coli in several other cases in Saskatchewan and British Columbia.

The latest list of recalled items can be found here, while information on the investigation and steps being taken can be found here.

E. coli was first detected at the plant on Sept. 4, but it took 12 days for the first of numerous public alerts to be issued.

It has led to the recall of hundreds of XL Foods beef products across Canada and much of the United States.

Harpreet Kochhar with the Public Health Agency of Canada said that XL Foods had a plan in place to battle E. coli, but didn’t follow or update that plan.

Federal Agriculture Minister Gerry Ritz, meanwhile, was under fire at the House of Commons this week, with the NDP demanding he apologize to Canadians and resign.

Ritz repeated that food safety remains a priority for the Harper government.

The minister said the XL plant will not be allowed to reopen until investigators are satisfied it is safe.
