Four Canadians became ill with Shigellosis in August. The Canadian Food Inspection Agency conducted an investigation and found a common exposure to be consumption of Los Angeles Salad Company's Genuine Sweet Baby Carrots. The agency issued a warning to the public, and Costco, where the carrots were carried in Canada, issued a voluntary recall on the bags with sell by dates of 8/13/2007. Bags were sold in Alberta, British Columbia, Ontario, Quebec and Newfoundland. The carrots were also distributed in the U.S. but no cases of Shigellosis developed. The carrots originated in Mexico.
