A wild sockeye salmon product sold in B.C. may be contaminated with Listeria monocytogenes, The Canadian Food Inspection Agency (CFIA) warned Thursday.

Vancouver-based Classic Smokehouse Inc. is voluntarily recalling the product.

Canadian Wild Sockeye Lox Trim was sold in 454g vacuum packages packed from May 2 to July 28, 2009.

The product was distributed in Vancouver, North and West Vancouver.

Classic Smokehouse President Stuart Dahlke said the Listeria monocytogenes does not apply to any of their hot-smoked salmon products.

"It only pertains to cold smoked products because cold smoked doesn't reach the highest temperature necessary to kill the bacteria."

Dahlke said three out of 11 production days tested positive for the bacteria.

"And these were at the middle, beginning and end of the dates," he said.

"But we're recalling them all just as a safeguard and then we're going to retest all new lots from now on."

There have been no illnesses reported with the consumption of this salmon product. Food contaminated with Listeria monocytogenes may not look or smell spoiled, according to the CFIA.

Consuming food with these bacteria may cause the food borne illness listeriosis, which can cause high fever, severe backache, neck stiffness and nausea.

Pregnant women, the elderly and people with compromised immune systems are particularly vulnerable.

The affected products bear UPC number 3000550008256.
