White Castle issued a voluntary recall for several varieties of its frozen hamburgers due to a “possible presence” of listeria, according to the Food and Drug Administration.
The affected products are the frozen six-pack cheeseburgers, frozen six-pack hamburgers, frozen six-pack jalapeno cheeseburgers and 16-pack hamburgers and 16-pack cheeseburgers with best-by dates ranging from Aug. 4, 2020 to Aug. 17, 2020.
“Any product with these dates on shelves is presently being removed. Any product with a best-by date before or after these best-by dates is not included in the voluntary recall,” the FDA said.
The agency had not received any reports of illness prior to the recall.
“White Castle conducts frequent and regular quality assurance tests,” the FDA said. “A recent sample conducted by a third party laboratory of its frozen sandwiches from one manufacturing facility showed a presence of Listeria monocytogenes halting any shipment of product to customers.”
“Since the problem was identified White Castle has not shipped any product from this facility to customers. Following rigorous safety testing protocols, all impacted production runs have been identified for destruction. White Castle has maintained complete control of all product produced at the facility since the first indication of a problem.”
Listeria can cause fatal infections in people with weakened immune systems, such as children or the elderly.
Symptoms include high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea. Pregnant woman who become infected can experience miscarriages and stillbirths, the FDA said.
Last week, multiple types of ready-to-eat salads, sushi and spring rolls from Fuji Food Products available at Trader Joe’s, Walgreens and 7-Eleven stores in 31 states and Washington, D.C. were recalled for similar listeria concerns.
