The recent outbreak of listeria linked to deli meat has sparked concerns among health officials and consumers alike.

The presence of listeria in the food supply chain has led to numerous outbreaks and recalls of contaminated products over the years. In 2018, a multistate outbreak of listeriosis linked to contaminated deli meats resulted in eight reported cases and one death. The following year, a similar outbreak traced back to enoki mushrooms sickened 36 individuals, leading to three deaths and several hospitalizations. Despite efforts to improve food safety regulations and inspections, listeria contamination remains a persistent threat in the food industry. The ability of listeria to thrive in cold temperatures and resist common sanitization methods makes it a particularly challenging pathogen to control.

People have reportedly become ill from the bacteria that can lead to foodborne illnesses, the Centers for Disease Control and Prevention announced Friday. The case sampled were collected between May 29 and July 5.

Casualties & Hospitalized

listeria outbreak linked to sliced deli meat has led to two deaths and 28 hospitalizations across the Midwest and East Coast, federal health officials revealed.

One person died in Illinois, as the state’s sole reported case, and another person died in New Jersey, according to CDC data.

Listeria is particularly concerning for those, who are pregnant, anyone 65 or older or are immuno-compromised. Listeria in pregnant women can cause miscarriage. Others can also be infected with listeria but rarely become seriously ill, according to the CDC.

  • New Jersey-1 death

The ages of the sick people range between 32 and 94 with the median being 75, CDC data showed.

The majority (72%) of the patients identified as white while 23% identified as Black or African American and 5% as Asian.

what is listeria?

Listeria is a type of bacteria that can cause serious illness in humans when consumed in contaminated food. It is a rod-shaped, gram-positive bacterium that is commonly found in soil, water, and the intestines of animals. Listeria is unique among foodborne pathogens because it can grow at refrigerator temperatures, making it a particularly dangerous pathogen. Listeria infection, also known as listeriosis, can result from consuming contaminated food, particularly unpasteurized dairy products, raw vegetables, deli meats, and smoked seafood. Pregnant women, newborns, the older people, and individuals with weakened immune systems are at the highest risk of developing severe complications from listeriosis.

Food manufacturers and retailers must prioritize strict sanitation protocols and regular testing to detect and eliminate potential sources of contamination. In response to the ongoing threat of listeria in the food supply, regulatory agencies like the FDA and USDA have implemented stringent guidelines for monitoring and controlling listeria in food processing facilities. These measures include regular testing of processing equipment, environmental surfaces, and finished products for listeria contamination.

Companies that fail to comply with these regulations risk fines, product recalls, and damage to their reputation. Consumers can also play a role in preventing listeria infection by practicing safe food handling at home and being vigilant about product recalls and warnings. By staying informed about listeria outbreaks and taking proactive steps to reduce the risk of contamination, individuals can protect themselves and their families from the potentially devastating effects of listeriosis.

What meat did they eat? What Brand?

CDC officials said 16 of 18 patients ate meats sliced at deli counters primarily deli-sliced turkey, liverwurst and ham. There are no specific recalls in place or brands identified so far.

Warning issued by CDC

The Centers for Disease Control and Prevention (CDC) issued a warning after at least 2 deaths were reported in connection to the outbreak. Listeria is a bacterium that can cause serious illness, especially in pregnant women, newborns, older adults, and people with weakened immune systems. The CDC’s warning comes as a reminder of the importance of food safety measures in preventing the spread of harmful bacteria.

Listeria can be found in a variety of foods, including raw vegetables, unpasteurized dairy products, and processed meats like deli meat.

The recent outbreak serves as a cautionary tale for both consumers and food producers to be vigilant in ensuring the safety of the food supply chain.

Advice of CDC

In response to the outbreak, the CDC has advised consumers to avoid eating deli meat unless it has been heated to an internal temperature of 165°F or until steaming hot.

This precautionary measure aims to kill any potential bacteria that may be present in the meat. Additionally, the CDC recommends washing hands and utensils thoroughly after handling deli meat to prevent cross-contamination. It is important for consumers to be aware of the risks associated with consuming deli meat and other processed foods.

Food producers play a crucial role in ensuring the safety of their products and preventing outbreaks like the recent listeria contamination. Proper sanitation practices, regular testing for harmful bacteria, and strict adherence to food safety regulations are essential in maintaining the integrity of the food supply chain.

Responsibility of Producers

In light of the recent outbreak, it is imperative for producers to review and enhance their safety protocols to prevent future incidents. The CDC’s warning serves as a wake-up call for both consumers and food producers to prioritize food safety and take necessary precautions to prevent the spread of harmful bacteria.

By following recommended guidelines for handling and preparing deli meat, consumers can protect themselves and their families from the risks of listeria infection.

Producers must also do their part in ensuring the safety of their products through rigorous quality control measures and compliance with food safety regulations. In conclusion, the recent listeria outbreak linked to deli meat underscores the importance of food safety in preventing the spread of harmful bacteria.

The CDC’s warning highlights the need for consumers to be vigilant in their food choices and for producers to prioritize safety measures in their operations. By working together to implement best practices in food production and consumption, we can reduce the risk of future outbreaks and protect public health. Let this serve as a reminder of the importance of food safety in safeguarding the well-being of our communities.

In this blog post, we will explore the causes, symptoms, treatments, and prevention strategies for listeriosis, the infection caused by Listeria bacteria

Causes:

Listeria monocytogenes is the bacterium responsible for causing listeriosis, a foodborne illness that can lead to severe complications, particularly in pregnant women, newborns, older people, and those with weakened immune systems. Listeria bacteria are commonly found in soil, water, and some animals, including poultry and cattle. They can also be present in raw and processed foods, such as unpasteurized dairy products, deli meats, and smoked seafood. Listeria can survive and even grow in refrigerated temperatures, making it resistant to many common food safety measures. This is why it is crucial to handle and store food properly to prevent the spread of Listeria contamination

Symptoms:

The symptoms of listeriosis can vary depending on the individual and the severity of the infection. In healthy individuals, symptoms may be mild and flu-like, including fever, muscle aches, and diarrhea. However, in vulnerable populations, such as pregnant women, older people, and those with weakened immune systems, listeriosis can lead to more severe symptoms, such as headache, stiff neck, confusion, loss of balance, and convulsions. Pregnant women infected with Listeria are at risk of miscarriage, stillbirth, premature delivery, or infection of the newborn. It is essential to seek medical attention if you experience any of these symptoms, especially if you fall into one of the high-risk groups.
