OTTAWA - A recall of sliced mushrooms produced by a company based in Aldergrove, B.C., is being expanded due to possible Listeria contamination.

The Canadian Food Inspection Agency recalled Champ's Mushrooms Sliced Mini Bella Mushrooms in a 680-gram package on June 7.

The CFIA has now added Sliced Crimini Mushrooms in 200 and 227 gram packages and President's Choice Crimini Sliced Mushrooms in a 454-gram package to the recall list.

The agency says there are no illnesses linked to the mushrooms, which were sold in British Columbia, but may have also been sold across the country.

Food contaminated with Listeria may not look or smell spoiled but can still make you sick.

Symptoms can include vomiting, nausea, persistent fever, muscle aches, severe headache and neck stiffness. Pregnant women, the elderly and people with weakened immune systems are particularly at risk.
