What is listeria?

Listeria monocytogenes is a bacterium that can cause listeriosis, a serious infection. It can also cause common food poisoning symptoms.

The Centers for Disease Control and Prevention says around 1,600 people get listeriosis every year, resulting in about 260 deaths. It is most likely to sicken pregnant women and their newborns, adults 65 and older, and people with weakened immune systems.

Invasive listeriosis happens when the bacteria spread beyond the gut to other parts of the body. Symptoms usually start within two weeks after eating food contaminated with listeria.

Symptoms in pregnant people are usually mild, with some never showing symptoms. However, the CDC says, infection during pregnancy commonly results in miscarriage, stillbirth, premature delivery, or life-threatening infection in the newborn.

In non-pregnant people, the CDC says, symptoms can be severe, with almost 1 in 20 people with invasive listeriosis dying.

Anyone who bought any of the listed cheeses is urged to throw them away. Customers can email Keswick Creamery directly at keswickrecall@gmail.com or call 1-800-946-1631 Monday thru Friday 10 a.m. to 2 p.m. ET to report their product and receive a full refund.
