The Smokehouse LLC of Mamaroneck, New York, is conducting a voluntary recall of PORTIER FINE FOODS Norwegian Smoked Salmon of various size packages including 4 oz., 8 oz., 16 oz. and random weight sizes, Batch Code 066 only, due to potential contamination with Listeria monocytogenes. Listeria monocytogenes is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.
