About 30,000 cases of a popular brand of hummus are being voluntarily recalled due to possible Listeria contamination.

The Sabra Dipping Company is recalling several versions of its Classic Hummus out of fear that it may contain traces of the organism, which can cause high fever, headaches, and nausea to healthy individuals and kill the very young and very old. Pregnant women infected with Listeria are especially at risk as it can lead to miscarriage and stillbirth.

A random sample collected from a retail location in late March tested positive for Listeria, according to a press release posted on FDA.gov. No illnesses have been reported, but the company is urging customers to dispose of or return the products for a full refund.

More information on the hummus recall is available at FDA.gov.
