Since July 24, there have been 55 additional illnesses in Canada reported in the ongoing investigation. Investigators have determined that red onions imported from the United States (U.S.) are a likely source of the outbreak.
Until more is known about the outbreak, individuals in British Columbia, Alberta, Saskatchewan, Manitoba, and Ontario are advised to not eat any red onions imported to Canada from the U.S., including any food products that contain raw red onions imported from U.S.. Retailers and restaurants in these locations are also advised not to use, sell or serve red onions imported from the U.S.. Red onions grown in Canada are not affected by this advice.
