ConAgra Foods Inc. (NYSE: CAG) announced Tuesday that it is recalling its Peter Pan and Great Value Peanut Butter brands as U.S. health officials investigate the products due to risk of salmonella contamination.

The Omaha, Neb.-based company said peanut butter with product code 2111 would be affected. The FDA issued a warning Thursday, based on a Center for Disease Control and Prevention saying there have been 288 cases of food poisoning in 39 states.

ConAgra said its product tests had not indicated salmonella presence, but was taking the precautions.

Consumers were asked to send questions or show condern could call a toll free number.
