Canada's food watchdog is updating an earlier recall of baby carrots after learning the product was distributed more widely than previously thought.

The Canadian Food Inspection Agency said Monday that Los Angeles Salad Company Baby Carrots, withdrawn for possible shigella contamination, were sold in Manitoba in addition to British Columbia, Alberta, Ontario, Quebec and Newfoundland.

Costco Wholesale is voluntarily recalling the carrots from the marketplace.

Four associated illnesses have been reported.

Shigella bacteria are found in the intestinal tracts of humans and other primates.

Food contaminated with shigella may not look or smell spoiled. Shigella infection can cause diarrhea, fever, nausea and vomiting.

The illness lasts from four to 14 days. Very young people, the elderly and people with compromised immune systems may experience more severe diarrhea.

Consumers with questions can call the CFIA at 1-800-442-2342 / TTY 1-800-465-7735.
