First Source, LLC of Buffalo, New York is voluntarily recalling 3,276 plastic tubs (6 oz.) of Wegmans Organic Walnut Halves & Pieces because the product may be contaminated with Salmonella, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Healthy persons infected with Salmonella often experience fever, diarrhea (which may be bloody), nausea, vomiting and abdominal pain.
