Sorry, hummus lovers: Sabra Dipping Company is voluntarily recalling many of its hummus products because of possible Listeria contamination.

The company has identified Listeria monocytogenes at one of its manufacturing facilities, the U.S. Food and Drug Administration said Saturday in a press release. However, the bacteria has yet to be found in its tested finished products.

The products were distributed to retail outlets in the United States and Canada, according to the FDA, and have a “Best Before” date up through Jan. 23, 2017. Consumers who are concerned they purchased one of the recalled products can find the date on the lid of each package, and are urged to throw out the potentially contaminated products.

Listeria is an organism that can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Pregnant women are also at risk, according to the FDA: A Listeria infection has been known to cause miscarriages and stillbirths. Symptoms usually include a high fever, severe headaches, stiffness, nausea, abdominal pain, and diarrhea.

Sabra products not included in the recall are: Sabra Organic Hummus, Sabra Salsa, Sabra Guacamole, and Sabra Greek Yogurt Dips.

This isn’t the first time the company has had to recall some of its products for listeria. In 2015, Sabra recalled 30,000 cases of its hummus products after traces of the bacteria were found.

A full list of recalled products is posted on Sabra and U.S. Food and Drug Administration websites.
