Several different companies have announced recalls in the last few days for products containing sunflower seeds that were sold in retail stores in Pennsylvania. The recalls were issued after SunOpta alerted companies it supplies that sunflower kernels it produced could be contaminated with listeria.

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.
