Sabra Dipping voluntarily recalled Thursday about 30,000 cases of its classic brand of hummus amid concerns over listeria contamination, the company’s Twitter account and the Associated Press reported. A link to a news release on the recall posted to Twitter didn’t work and the company’s website appeared to be down early Thursday morning.

The recall affects classic hummus tubs with May 11 and May 15 expiration dates, Sabra said on Twitter. AP reported that the recalled products include:

-- 10-ounce size Sabra Classic Hummus with a UPC/SKU number 040822011143/300067;

-- 30-ounce Sabra Classic Hummus, 040822014687/300074;

-- 32-ounce Sabra Classic Hummus with Garnish, 040822342049/301216;

-- 17-ounce Sabra Classic Hummus six packs, 040822017497/301290;

-- Hummus Dual Pack Classic/Garlic, 040822342209/301283.

Anyone who bought one of the affected items should discard the package, the Detroit Free Press reported. Customers also may return the hummus to the store they bought it to get a refund, according to the Free Press.

Concern over listeria in Sabra hummus was sparked during a routine inspection March 30 at a Kroger supermarket in Port Huron, Michigan, the Detroit Free Press reported. Samples of the hummus were tested and were found to have potentially contained listeria, which led the Michigan Department of Agriculture and Rural Development to alert officials at the U.S. Food and Drug Administration. However, there have been no cases of anyone becoming infected after eating Sabra hummus.

Listeria causes listeriosis, an infection whose symptoms include fever, muscle aches, diarrhea and gastrointestinal symptoms, the Centers for Disease Control and Prevention said. If the infection spreads to the nervous system, it can cause headache, stiff neck, convulsions, loss of balance and confusion or changes in alertness, the Mayo Clinic said.

Older people, pregnant women, newborns and adults with weakened immune systems are at greatest risk for the infection. About 260 people die from listeria every year and 1,600 become sick from the infection, the CDC said. The infection is treated with antibiotics.
