Sabra Dipping Company has issued a voluntary recall for some of its hummus products over potential listeria contamination, the manufacturer announced Saturday.

The decision comes after Sabra’s manufacturing facility tested positive for the bacterium Listeria monocytogenes, which can cause a serious and potentially deadly infection, the U.S. Food and Drug Administration said in a release. (Sabra, headquartered in White Plains, New York, has factories in Virginia, California and New York.)

The affected products were made prior to Nov. 8, and have a “best before” date up to and including Jan. 23, 2017. This date can be found on the lid of each package. The recall does not affect Sabra Organic Hummus and Sabra Guacamole, Sabra Salsa or Sabra Greek Yogurt Dips, according to the FDA.

The full list of recalled products can be seen on the FDA website.

Though none of the products tested positive for contamination, the company said it was issuing the recall “out of an abundance of caution.”

Anyone who has a product affected by the recall can contact the company through its website to receive replacement coupons.

Sabra issued a similar recall a year and a half ago. In April 2015, 30,000 cases of its classic hummus were recalled nationwide over possible listeria contamination after a store-bought Sabra hummus product tested positive for the bacterium.

Sabra Sabra Spreads are among the recalled products. The flavors include: Spicy Chili, Garlic Herb, Honey Mustard and Salt & Pepper.

Listeriosis, the disease that results from listeria infection, can be especially harmful to older adults, pregnant women, newborns and people with weakened immune systems, according to the Centers for Disease Control and Prevention.

Symptoms can include fever, muscle aches, diarrhea or other gastrointestinal systems.

“Almost everyone who is diagnosed with listeriosis has ‘invasive’ infection, in which the bacteria spread beyond the gastrointestinal tract,” the CDC says.
