Caesar salad recalled over possible Listeria contamination

The Canadian Food Inspection Agency has put a recall notice on three brands of caesar salad products because of possible Listeria contamination. 

These products have been sold in Buy-Low Foods and Nesters Market stores in British Columbia and Alberta.

They were also sold at at the Safeway and St. Martin's Family Food stores in Alberta, British Columbia, Manitoba, Ontario and Saskatchewan. 

The agency said people should check to see if they have these products in their homes. If so, they should throw them out or return them to the store where they purchased them. 

Food contaminated with Listeria may not look or smell spoiled, but it can make people sick. 

Symptoms include: vomiting, nausea, persistent fever, muscle aches, severe headache and neck stiffness. 

Pregnant women, elderly people, and those with compromised immune systems are particularly at risk

Recalled products should be thrown out or returned to the store.

Here are the brands to look out for. Spelling follows the actual labels:
