Sabra Dipping Co. is recalling many varieties of its hummus products sold in the United States and Canada because they could have listeria contamination, according to a news release.
The organism was identified at the manufacturing plant but hasn't been found in the finished product.
More than 20 flavors in multiple sizes are being voluntarily recalled. Any Sabra hummus product with a "best before" date through Jan. 23, 2017, should be thrown away. Product codes and "best before" dates are on the lid of each package.
Sabra's organic hummus, salsa, guacamole and Greek yogurt dips aren't affected.
Listeria monocytogenes can cause serious and sometimes fatal infections in young children, the elderly or people with weakened immune systems. Symptoms in healthy people include high fever, severe headaches, stiffness, nausea, abdominal pain and diarrhea.
The infection can also cause miscarriages and stillbirths, according to the FDA.
A list of the recalled products can be found on the FDA website or at sabra.com/recall.
The company recalled about 30,000 cases of hummus for a potential listeria contamination in April 2015.
