A company based in Tennessee has recalled three brands of hummus with pine nut topping due to possible Listeria contamination.
House of Thaller issued the recall after its supplier of pine nuts, Hudson Valley Farms Inc., discovered the bacteria in one of its production facilities.
"Routine sampling of a different item produced by the supplier for a different company revealed positive Listeria monocytogenes findings," the company stated, according to the U.S. Food and Drug Administration. "HVF, Inc. is recalling all products made in their facility during the time of the potential contamination."
The hummus was distributed between April and June to retail stores across the country -- including Walmart, Target, HEB and Giant Eagle -- under the brand names Fresh Foods Market, Lantana and Marketside. It was also distributed to stores in Canada.

House of Thaller emphasized that the recall only applies to hummus containing pine nuts.
"No other brands or flavor varieties produced at our manufacturing plant are affected by this recall," the recall notice states. "We are dedicated to our customer satisfaction and will be refilling store shelves as quickly as possible."

Hudson Valley Farms has suspended production operations and will not resume until it gets the green light from the FDA.
"The FDA is working with Hudson Valley Foods Inc. to facilitate their recall and remove potentially contaminated food from the marketplace," an FDA spokesperson told Food Safety News. "Additionally, the firm is working on corrective actions to remediate the situation and identify the source. We have no further information to share at this time."
Consumers can check to see if their product is affected by the recall by checking the expiration date and lot code stamped on the package. All the types of hummus affected are 10-ounce packages. For a full recall list, see the FDA recall page.
Eating food contaminated by Listeria monocytogenes can lead to a serious infection called listeriosis, reports CNN. The Centers for Disease Control and Prevention notes that around 1,600 people get listeriosis every year. Around 260 of those cases are fatal.
Common symptoms of listeriosis include headache, stiff neck, muscle aches, fever, abdominal pain, nausea, diarrhea, confusion and loss of balance. The infection is particularly dangerous for pregnant women, elderly people, young children and anyone else with a suppressed immune system.
For pregnant women, exposure to Listeria increases their risk of miscarriage, stillbirth and premature delivery.
