The maker of Peter Pan peanut butter has extended its recall following a salmonella outbreak.

ConAgra Foods said all peanut butter produced in its Georgia plant dating back to 2004 should be discarded.

The recall covers all Peter Pan peanut butter and all Great Value peanut butter beginning with product code 2111, including peanut butter toppings.

The company's initial recall only covered peanut butter produced at the Sylvester, Ga., facility since December 2005.

The Centers for Disease Control and Prevention linked 425 cases of salmonella to the peanut butter.
