Green Valley Food Corp. has recalled approximately 35,159 cases of a variety of products because they have the potential to be contaminated with Listeria monocytogenes. Random samples tested positive for 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. 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.
