An outbreak of Listeria linked to sliced deli meats has resulted in 34 illnesses in 13 U.S. states, according to the CDC.
The outbreak has led to the recall of all ready-to-eat meat and poultry products produced by Boar’s Head Provisions Co. Inc., in Jarratt, Va. Testing has identified Listeria in an unopened package of Boar’s Head liverwurst, which was collected as part of the CDC investigation. Since Listeria can spread easily on surfaces such as deli counters, equipment, hands and food, the risk for additional contamination is substantial.
As of July 31, the outbreak has hospitalized 33 people; two people have died, and officials stress that additional cases may be identified.
“There are a few reasons additional illnesses could be reported,” said Laura Gieraltowski, PhD, the team lead of the CDC’s Foodborne Outbreak Response Team. “There is a risk of cross-contamination of deli areas at stores. If these areas were not properly cleaned, even after the recall, there could be more illnesses.
“There also can be a delay in when CDC finds out about cases, and there can be a long incubation period,” Dr. Gieraltowski added. “So even if all the contaminated products and equipment were removed, we’d still likely hear about more illnesses.”
The CDC has recommended sanitation practices for both businesses and consumers who may have sold or purchased the recalled meats. The agency also has emphasized the importance of protecting against Listeria infection for individuals who are at high risk, including those who are pregnant, at least 65 years of age or have weakened immune systems.
“Healthcare professionals can help communicate that although Listeria infections are rare, they can have devastating outcomes for people who are pregnant or immunocompromised,” Dr. Gieraltowski said. “These infections can result in pregnancy loss or, sadly, even death. If people who are at higher risk of infection would like to eat deli meats, CDC recommends heating them to 165? F before eating since Listeria germs are easily killed by heating.”
Dr. Gieraltowski reported no relevant financial disclosures.
