United Natural Trading LLC, d/b/a Woodstock Farms Manufacturing, Edison, NJ, is voluntarily recalling a limited number of lots of conventional walnuts and walnut-containing products (see attachment for products and lot numbers) that were purchased from Gibson Farms and sold under the Nature’s Promise, Woodstock, Market Basket, and Woodfield Farms brands due to a possible health risk from 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 symptoms. 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.

The lot numbers are printed on the back of each retail bag. The walnut and walnut-containing products were shipped to retailers and distributors in limited quantities throughout the United States.

The recall was issued as a precaution because a single sample in a finished product yielded a positive result for Listeria monocytogenes.
