Peanut and almond butter sold at several major retailers is being recalled for potential salmonella contamination, according to the Food and Drug Administration.

The nut butters affected by the recall include store brands from Whole Foods, Trader Joe's, Kroger and Safeway, among others.

A full list of the recalled products can be found on the FDA's website.

Food producer nSpired Natural Foods Inc. voluntarily recalled the products after routine FDA testing found the foods were at risk for contamination.

Possibly contaminated products have been delivered to the United States, Canada, Hong Kong, Dominican Republic and the United Arab Emirates.

So far, four cases of illness have been reported that may be linked to the products.

Salmonella can cause serious and sometimes fatal infections in young children, the elderly and people with weakened immune systems.

Symptoms of salmonella poisoning include nausea, vomiting, diarrhea and abdominal pain. In rare cases, salmonella can cause arterial infections, endocarditis and arthritis.

While salmonella contamination is often tied to eggs and poultry, outbreaks have been linked to peanut butter in the past.

In 2012, peanut butter processor Sunland Inc. recalled nut butters sold at Trader Joe's after a salmonella outbreak spread across 20 U.S. states.

The FDA has instructed consumers with recalled jars of peanut or almond butter to throw the products away and call nSpired Natural Foods at 1-800-937-7008 for a replacement jar or refund.
