Officials advised checking kitchens and freezers and discarding or returning any recalled products.

The FSIS expects more updates as this investigation continues. As more information becomes available, FSIS will update this public health alert. Consumers should check back frequently.

The foods may be contaminated with Listeria monocytogenes (Lm), a foodborne bacterium that causes the serious infection listeriosis, particularly in older adults, pregnant women, newborns, and people with weakened immune systems.

According to the FSIS, Listeriosis can cause fever, muscle aches, headache, stiff neck, confusion, loss of balance and convulsions sometimes preceded by diarrhea or other gastrointestinal symptoms.

An invasive infection spreads beyond the gastrointestinal tract.

In pregnant women, the infection can cause miscarriages, stillbirths, premature delivery or life-threatening infection of the newborn.

In addition, serious and sometimes fatal infections can occur in older adults and persons with weakened immune systems.

Listeriosis is treated with antibiotics.

Persons in the higher-risk categories who experience flu-like symptoms within two months after eating contaminated food should seek medical care and tell the health care provider about eating the contaminated food.
