NEW YORK (MainStreet) -- Turkish pine nuts are at the root of a major salmonella recall Wegmans Food Markets issued Wednesday night.

The Food and Drug Administration announced Wednesday that 5,000 lbs. of Turkish pine nuts sold in the bulk section of Wegmans stores in New York, Pennsylvania, New Jersey, Virginia and Maryland have been linked to an outbreak of salmonella, and that customers who have purchased the pine nuts should discard them and visit their local Wegmans for a full refund. The supermarket chain is already calling customers who purchased the Turkish pine nuts with their Shoppers Club card to alert them of the recall.

The recall applies only to Turkish pine nuts sold in bulk.

As MainStreet has reported, most people infected with salmonella generally develop diarrhea, fever and abdominal cramps 12 to 72 hours after exposure. Infections can be life threatening, especially to those with weak immune systems, such as infants, the elderly and persons who are undergoing chemotherapy or have HIV. Anyone experiencing these symptoms should visit his or her health care provider immediately.
