The Canadian Food Inspection Agency has recalled certain mushrooms sold in Ontario and Quebec because they may cause listeriosis, which can cause high fever, severe headache, neck stiffness and nausea.

No illness has been reported as a result of eating the mushrooms.

The recall covers three brands produced by Continental Mushroom Corporation Ltd. of Ottawa:

- Continental/Quickslice Triple Washed, product code 0 64798 00005 5.
- Fresh Obsessions/Pre-Washed Sliced White Mushrooms, product code 0 69200 00902 2.
- Fresh Obsessions/Sliced Crimini (Italian Brown) Mushrooms, product code 0 69200 00502 4.

All three products in 227-gram packages with a lot code beginning with 200 to 214.

Food contaminated with the bacteria Listeria monocytogenes may not look or smell spoiled, but can still cause listeriosis. At its worst, an infection during pregnancy can lead to premature delivery, infection of the newborn, or even stillbirth.
