CHICAGO (CBS) – Smoked salmon sold at Illinois Sam’s Clubs is the subject of a recall over listeria concerns.

Multiexport Foods, Inc of Miami, FL is expanding the voluntary recall that it launched Saturday, December 22nd, 2012 of cold smoked salmon, 12 oz Twin Pack and the 1.25 lb Pack under the “Paramount Reserve”, because it has the potential to be contaminated with Listeria monocytogenes, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems.

Healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea. The recall is being expanded to include additional lot-sublot-batch codes.
