TIMMINS -- The investigation into what's causing some Canadians to get sick from eating imported onions is still under investigation, but health officials say people should be cautious about what they eat.

"If we don't know where your onions are from, if there's not a product number on them or a sticker to indicate where they come from, we don't know, so our recommendation remains not to consume those onions," said Sandra Lapajne, public health inspector with the Porcupine Health Unit.

With more than 100 people experiencing salmonella poisoning linked to Thomson International Onion, originating in Bakersfield, Calif., Lapajne encourages people to sign up for social media or phone alerts from Canada's Food Inspection Agency.

"We do recommend that the public do follow Canadian Food Inspection Agency for the recall information so that they're staying up to date on the information," said Lapajne.

You can also receive email notifications about food recalls from the Canadian Food Inspection Agency. You can tailor your alerts to suit your needs. For example, you can request all high-risk warnings or to hear about specific allergens. The agency issues about 300 email notifications a year.
