(NewsNation) — The J.M. Smucker Company is recalling select Jif peanut butter products due to possible salmonella contamination, according to the Food & Drug Administration.

Salmonella is an organism that can cause severe and sometimes fatal infections in children, people with weak immune systems and the elderly.

Five people contracted salmonella from eating Jif peanut butter products, Dr. Anthony Harris told NewsNation.

“The hallmark symptoms people present with are nausea, vomiting, diarrhea. Fever is also a part of it, abdominal cramps are a very prominent feature of salmonella poisoning,” Harris said.

Salmonella is generally found in perishable products, such as chicken, beef and eggs, but it can enter peanut butter by means of contaminated water or soil.

Harris said treatment for salmonella is straightforward: “hydrate, hydrate, hydrate.”

The recalled peanut butter produced at a plant in Lexington, Kentucky and was distributed nationwide.

If you have any of these products, you should dispose of them immediately.

This recall is being conducted in cooperation with the U.S. Food and Drug Administration.
