The recent listeria outbreak linked to deli-sliced meat has resulted in the death of at least two people and has hospitalized more than two dozen across twelve states. This alarming situation has drawn attention to the risks associated with consuming deli meats and the importance of food safety measures.
Outbreak Details
The Centers for Disease Control and Prevention (CDC) reported that the fatalities occurred in Illinois and New Jersey. In total, 28 people have been hospitalized since May, with cases spanning from New York to Virginia. The outbreak has been traced back to deli-sliced meats, with many affected individuals reporting that they consumed meat from deli counters.
Affected States and Demographics
The most cases were reported in New York, followed by Maryland. Other states reporting cases include Georgia, Illinois, Massachusetts, Minnesota, Missouri, New Jersey, North Carolina, Pennsylvania, Virginia, and Wisconsin. The patients ranged in age from 32 to 94 years, including one pregnant individual who has since recovered. The CDC warns that the actual number of infections could be higher due to underreporting of milder cases.
Source and Spread
Listeria monocytogenes, the bacteria responsible for the outbreak, is naturally found in soil and can contaminate various foods. It spreads easily in deli environments, including equipment, surfaces, and hands. Importantly, refrigeration does not kill listeria, making reheating meats to a high temperature before consumption crucial to prevent infection.
Investigation and Prevention
Public health investigators are using whole genome sequencing to identify the DNA fingerprints of the bacteria and trace the source of contamination. The U.S. Department of Agriculture’s Food Safety and Inspection Service is working to identify the suppliers of the affected deli meats.
The CDC has issued guidance to avoid eating deli meats unless they are thoroughly reheated. They emphasize that there is currently no evidence linking prepackaged deli meats to the outbreak. The agency is also collaborating with state and local health departments to gather detailed information on the outbreak and to identify any common sources of contamination.
Symptoms and At-Risk Groups
Listeria infection can cause severe symptoms such as fever, muscle aches, and fatigue. For pregnant women, it can lead to pregnancy loss, premature birth, and serious infections in newborns. Individuals over 65 or with weakened immune systems are particularly vulnerable, often requiring hospitalization and facing higher risks of death.
Understanding Listeria
Listeria monocytogenes is a type of bacteria commonly found in soil and water. It can contaminate food at various stages, from farming to processing to distribution. Once ingested, the bacteria can cause listeriosis, a serious infection that affects the digestive system and can spread to other parts of the body.
Listeria is unique among foodborne pathogens because it can grow at refrigeration temperatures, making it a persistent threat in refrigerated foods. This characteristic underscores the importance of proper food handling and storage practices to minimize the risk of contamination.
Recent Related Outbreaks
This listeria outbreak is the second significant one in the U.S. this summer. Earlier, a Maryland-based food manufacturer had to recall multiple brands of ice cream due to potential listeria contamination. Additionally, Canada recently reported fatalities linked to plant-based milk alternatives contaminated with listeria.
In 2023, several listeria outbreaks were reported, including those linked to leafy greens, ice cream, and stone fruits such as peaches, nectarines, and plums. These incidents highlight the diverse range of foods that can be affected by listeria contamination and the importance of vigilance in monitoring food safety.
Prevention Tips for Consumers
To protect yourself and your family from listeria, follow these food safety tips:
- Reheat Deli Meats: Always reheat deli-sliced meats to steaming hot before eating.
- Clean Surfaces and Equipment: Regularly clean and sanitize kitchen surfaces, cutting boards, and utensils.
- Store Foods Properly: Keep raw and cooked foods separate to avoid cross-contamination.
- Monitor Recalls: Stay informed about food recalls and safety alerts related to listeria.
- Practice Good Hygiene: Wash hands thoroughly with soap and water before and after handling food.
Conclusion
This outbreak underscores the importance of food safety and the need for vigilance when consuming deli meats. Reheating meats to appropriate temperatures and adhering to food safety guidelines can significantly reduce the risk of infection. Public health authorities continue to monitor the situation closely to prevent further cases and ensure consumer safety.
