XL Foods workers listen to Doug O'Halloran, president of the United Food and Commercial Workers Local 401, during a news conference stating that XL Foods are still refusing to address food safety issues flagged by the union in Brooks, Alberta, October 10, 2012. Ten people have now fallen sick from contaminated beef products from the XL Foods plant, health officials said on Saturday. Four previous cases were also in Alberta, and officials say they have evidence that these victims ate meat produced by the XL Foods plant in Brooks, Alberta. The Canadian officials said the six new cases were caused by the same strain of the E. coli bacteria as the previous cases. REUTERS/Todd Korol (CANADA - Tags: BUSINESS FOOD)
