A popular snack food is being recalled because of fears it could be contaminated with salmonella.

Robert's American Gourmet said it's recalling all lots and sizes of Super Veggie Tings Crunchy Corn Sticks Snack Food sold across the United States and Canada. The snack was sold through local distributors, Internet sales, phone orders, mail orders and retail outlets.

The firm said the recall is precautionary. The product contains the same seasoning as the Veggie Booty Snack Food recalled last week.

Super Veggie Tings Crunchy Corn Sticks are packed in flexible, plastic foil bags in a 6 ounce size, and has a UPC code 15665-10356. The brand name is Robert's American Gourmet and all codes and expiration dates of Super Veggie Tings Crunchy Corn Sticks are being recalled.

The original recall was prompted by 54 cases of salmonella poisoning in 17 states. Many of those infected reported eating Veggie Booty.

Roberts American Gourmet said the company is extensively investigating to determine the source of the contamination, but in the meantime it has ceased production and distribution of both products pending results of the investigaion.

Salmonella is an organism that can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Healthy people infected with Salmonella often experience fever, diarrhea (which may be bloody), nausea, vomiting and abdominal pain.

In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as arterial infections, endocarditis and arthritis.
