OHIO (AP) — Consumers should double-check their jars of Jif peanut butter amid a recall, the Food and Drug Administration and the Centers for Disease Control and Prevention say.

Jif’s creamy, crunchy, natural and reduced fat peanut butters have been linked to a salmonella outbreak across 12 states that has left 14 ill, with two people being hospitalized. Side effects from salmonella poisoning include fever, diarrhea, nausea and vomiting.

The J.M. Smucker Co. announced a voluntary recall Friday of some Jif peanut butter products for potential salmonella contamination. Jars with lot codes 1274425 through 2140425 have been recalled and should be disposed, the company said.

The FDA investigation linked the outbreak to Jif brand peanut butter produced in the J.M. Smucker Company facility located in Lexington, KY. 

The recomendation from the FDA is for consumers, restaurants, and retailers should not eat, sell, or serve any recalled Jif brand peanut butter that have lot code numbers 1274425 through 2140425, only if the first seven digits end with 425 (manufactured in Lexington, Kentucky.) The product has a two year shelf life and Jif peanut butter already in homes should be checked. 

Jif is sold at retailers nationwide. States reporting salmonella cases are Arkansas, Georgia, Illinois, Massachusetts, Missouri, Ohio, North Carolina, New York, South Carolina, Texas, Virginia and Washington.
