St. Louis ? A supermarket chain here is pulling its brand of French style green beans from the shelves of more than 100 stores because of concerns about possible contamination.

Schnucks, with stores primarily in the St. Louis area and across the Midwest, said Wednesday it was recalling Schnucks Blue Lake French Style Green Beans from all Schnucks and Logli stores.

The company said a batch of green beans may have been undercooked and could be contaminated with harmful organisms.

Customers in Missouri, Illinois, Indiana, Wisconsin, Tennessee, Mississippi and Iowa can return the green beans to their local stores for a refund, the company said. No other products are involved in the recall.
