Unwrapped field cucumbers are being recalled by major B.C. grocery outlets due to possible salmonella contamination.

Safeway recalled its bulk-sold field cucumbers Sunday, along with in-store products bought on or before Sept. 6 that contained them, such as salads, vegetable trays, sushi and sandwiches.

That recall was expanded Tuesday to include field cucumbers sold in or before Sept. 4 by the Overwaitea Food Group through its Save On Foods, PriceSmart, Coopers Foods, Overwaitea and Freson Brothers outlets.

There are no known cases of illness in Canada, according to the Canadian Food Inspection Agency.

The Canadian recalls came in response to a recall by a California producer and may be linked to an outbreak in the U.S., the CFIA said.

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

Salmonella-contaminated food may not look or smell spoiled but can still make people sick.

Young children, pregnant women, the elderly and people with weakened immune systems may contract serious and sometimes deadly infections.

Healthy people may get short-term symptoms such as fever, headache, vomiting, nausea, abdominal cramps and diarrhea.
