The Centers for Disease Control and Prevention (CDC), in collaboration with state health officials and the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA-FSIS), has concluded its investigation into a Listeria monocytogenes outbreak linked to deli-sliced meats. The outbreak, which affected 19 states, is now officially over. However, the CDC continues to urge individuals at higher risk, including those who are pregnant, aged 65 or older, or immunocompromised, to avoid deli meats or ensure they are reheated to an internal temperature of 165°F before consumption.
Key Findings from the Investigation
Between May 29, 2024, and September 13, 2024, a total of 61 cases of Listeria infection were reported across 19 states. Tragically, the outbreak resulted in 10 deaths. Those affected ranged in age from 32 to 95, with a median age of 78. The majority of individuals who fell ill were hospitalized, underscoring the severity of Listeria infections, particularly among vulnerable populations.
Public health data identified meats sliced at deli counters as the primary source of contamination, including specific reports implicating Boar’s Head liverwurst. Of the individuals interviewed:
- 94% reported consuming deli meats.
- 96% of those reported eating meats sliced at deli counters.
- 61% of respondents who ate liverwurst specifically consumed deli-sliced liverwurst, with many naming the Boar’s Head brand.
Public Health Actions Taken
In July 2024, Boar’s Head voluntarily recalled all deli products manufactured at their Jarratt, VA facility, including prepackaged and ready-to-eat liverwurst, due to confirmed Listeria contamination. These products are now past their shelf-life and should no longer be available for purchase.
Advice for At-Risk Populations
The CDC advises individuals at higher risk for Listeria infections to:
- Avoid consuming deli meats unless they are reheated to 165°F.
- Practice safe food handling to minimize cross-contamination.
Ongoing Challenges
While the outbreak has been declared over, public health officials warn that the true number of cases may have been higher. Many individuals recover without medical care and are not tested for Listeria. Additionally, delays in reporting and testing may have impacted the final case count.
Swine Industry Implications
For pork producers, processors, and retailers, this outbreak serves as a reminder of the importance of stringent food safety measures throughout the supply chain. From farm to deli, ensuring the highest standards of cleanliness and proper handling can mitigate risks of contamination.
As part of the swine industry, staying informed about consumer food safety concerns is critical to maintaining trust and ensuring the health of end consumers. Whether it’s through education, innovation in product safety, or proactive recall management, the industry must continue to prioritize public health and transparency.
