“We are cooperating fully with government authorities and conducting our own investigation into this incident,” the Sarasota-based meats company said in a statement.

The listeria outbreak was first reported last week.

Since late May, 34 people were sickened across 13 states, with all but one hospitalized. Two people died — in Illinois and New Jersey. It can take weeks for symptoms to develop, so there might be more cases, officials said.

People most commonly reported eating deli-sliced turkey, liverwurst and ham, officials said.

Listeria can contaminate food and sicken people who eat it. Symptoms include fever, muscle aches, nausea and diarrhea. It can be treated with antibiotics, but it is especially dangerous to pregnant women, newborns, the elderly and those with compromised immune systems.

An estimated 1,600 people get listeria food poisoning each year and about 260 die, according to the Centers for Disease Control and Prevention.

The Boar’s Head recall of over 200,000 pounds shipped nationwide applies to meats sliced at a deli counter, not prepackaged meats.

It includes a number of multi-pound packages stamped with an Aug. 10 sell-by date, including bologna, garlic bologna, beef bologna, beef salami, Italian Cappy-style ham and Extra Hot Italian Cappy-style ham. Also included is Steakhouse Roasted Bacon Heat and Eat, with a sell-by date of Aug. 15.

The company said customers should throw away the recalled products, or return them to the store for a refund. Health officials said refrigerators should be thoroughly cleaned to prevent contamination of other foods.
