Boar's Head Provisions is recalling all of its liverwurst products on store shelves because it could contain listeria, the U.S. Food and Safety Inspection Service said Friday.

The announcement comes as health officials investigate a listeria outbreak that has sickened 34 people and caused two deaths in more than a dozen states. Boar's Head also said some of its deli meat products could contain listeria, a type of bacteria that can cause illness known as listeriosis. The Sarasota, Florida-based company said it is recalling a total of more than 103 tons of meat.

Safety regulators warned consumers who have purchased potentially affected Boar's Head products not to eat them and urged retailers to pull the meat from stores. Some grocery chains have temporarily closed their respective delis due to the outbreak, CBS Boston reported. The recalled liverwurst products were produced between June 11 and June 17, with a shelf life of 44 days.

The products are for sale at retail delis nationwide, according to the recall notice. Boar's Head sells liverwurst in 3.5 pound loaves encased in plastic, as well as in other weights, and in sliced form.

The liverwurst's label reads, "Boar's Head Strassburger Brand Liverwurst." The liverwurst products under recall have sell-by dates that range from July 25 to Aug. 30.
