WASHINGTON (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 lot number can be found printed near the best-by date.

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