Trader Joe's has recalled batches of butter chicken with basmati rice amid fears of possible contamination from the listeria bacteria.

The recall alert has been announced by The United States Department of Agriculture's Food Safety and Inspection Service and Canadian Food Inspection Agency. More than 4,000 pounds of the product might be contaminated with Listeria monocytogenes bacterium.

Products imported to the United States include 12.5 oz boxes of "Trader Joe's Butter Chicken with Basmati Rice" with product code "2012-10-31" and lot code "30512", said FSIS.

The product is supplied to Trader Joe's by Aliya's Foods Limited., in Canada.

The contamination was detected at one production line during routine testing. Subsequent testing of the products by the company, however, has shown no presence of Listeria.

The potential contamination was detected on one production line during routine testing. Subsequent testing conducted by the company, and verified by the CFIA, has shown no additional evidence of Listeria contamination.

"Customers who have purchased this item are urged to not eat it, and to dispose of it or return it to any Trader Joe's for a full refund," said a statement from Trader Joe's.

Consuming products that have been contaminated with Listeria monocytogenes can cause an infection called as listerosis. The infection usually occurs in old people or people with a weak immune system. Pregnant women and newborns are also at risk of getting this infection.

Common symptoms of the infection include fever, headache, neck stiffness, and muscle aches with gastrointestinal problems. Listeroisis can even cause miscarriages and stillbirths.
