Sabra Dipping Co. is recalling 30,000 cases of hummus due to possible contamination with Listeria, the U.S. Food and Drug Administration said Wednesday.
The nationwide recall is voluntary.
So far, no illnesses caused by the hummus have been reported.
The potential for contamination was discovered when a routine, random sample collected at a Michigan store on March 30 tested positive for Listeria monocytogenes.
The FDA issued a list of the products in the recall. Anyone who has purchased any of the items is urged to dispose of or return it to the store for a full refund.
Listeria monocytogenes can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems, the FDA says.
Although some people may suffer only short-term symptoms such as high fever, severe headache, nausea, abdominal pain and diarrhea, Listeria can also cause miscarriages and stillbirths among pregnant women.
