U.S. health officials Friday announced a recall of some Boar’s Head liverwurst and other deli meats as they investigate a listeria outbreak that has sickened nearly three dozen people and caused two deaths.

Boar’s Head Provisions Co. recalled its liverwurst because it may be tainted with the listeria bacteria, the U.S. Agriculture Department said. The company is also recalling additional deli meats that were produced on the same line and on the same day as the liverwurst.

The USDA said a sample of Boar’s Head liverwurst from a Maryland store tested positive for listeria. The sample was from an unopened package, collected by the Maryland Department of Health as part of an investigation into the listeria outbreak.

Testing is underway to determine if the liverwurst sample is connected to the outbreak, health officials said.

The outbreak was first reported last week. As of Thursday, 34 people were sickened, with all but one hospitalized. Two people died including one from Illinois.

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 includes a number of products stamped with an August 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 director of the Secret Service said Tuesday she’s resigning following the assassination attempt against ex-President Donald Trump that unleashed intensifying outcry about how the agency tasked with protecting current and former presidents could fail in its core mission.

Kimberly Cheatle, who had served as Secret Service director since August 2022, had been facing growing calls to resign and several investigations into how the shooter was able to get so close to the Republican presidential nominee at an outdoor campaign rally in Pennsylvania.

“I take full responsibility for the security lapse,” she said in an email to staff, obtained by The Associated Press. “In light of recent events, it is with a heavy heart that I have made the difficult decision to step down as your director.”

Cheatle’s departure was unlikely to end the scrutiny of the long-troubled agency after the failures of July 13, and it comes at a critical juncture ahead of the Democratic National Convention and a busy presidential campaign season. Lawmakers on both sides of the aisle have promised continued investigation, along with an inspector general probe and an independent and bipartisan effort launched at President Joe Biden’s behest that will keep the agency in the spotlight.

Cheatle’s resignation came a day after she appeared before a congressional committee and was berated for hours by both Democrats and Republicans for the security failures. She called the attempt on Trump’s life the Secret Service’s “most significant operational failure” in decades and said she took full responsibility for the security lapses, but she angered lawmakers by failing to answer specific questions about the investigation.

Biden said in a statement that “we all know what happened that day can never happen again,” and he said he’d appoint a new director soon, but he did not discuss a timeline.

The president said he was grateful to Cheatle for her decades of public service. “We especially thank her for answering the call to lead the Secret Service during our administration and we are grateful for her service to our family,” Biden said
