Listeria Outbreak In US Linked To Ready-To-Eat Meat; Symptoms To Look Out For

Outbreak Overview

The Centers for Disease Control and Prevention (CDC) has identified the source of the outbreak as ready-to-eat meat products produced by Yu Shang Food, Inc., located in Spartanburg, South Carolina. The affected individuals span across New York, New Jersey, Illinois, and California, with California reporting the highest number of cases, including the death of an infant.

All the individuals affected identify as being of Asian heritage. This suggests that cultural dietary habits might have played a role, as Yu Shang Food products are often sold in markets frequented by the Asian community. Notably, seven of the individuals reported purchasing food from these markets, and two specifically recalled consuming Yu Shang Food’s chicken products.

The outbreak investigation intensified following a routine inspection by the U.S. Department of Agriculture (USDA) on October 21. Inspectors detected the presence of Listeria monocytogenes in meat products at the Yu Shang Food facility. This finding prompted an initial recall on November 9, which was subsequently expanded. Following these discoveries, Yu Shang Food has suspended operations and initiated a product recall.

Impact on Families

Among the most devastating outcomes of this outbreak was the death of an infant who was part of a twin pair. While listeria was detected in the deceased infant and the mother, the death of the second twin could not conclusively be linked to the infection. The mother, who contracted the illness during pregnancy, has since recovered. Another infant, unrelated to this family, also fell ill but fortunately survived.

What Is Listeria Infection?

Listeria infection, also known as listeriosis, is caused by the bacterium Listeria monocytogenes. This foodborne illness is most commonly associated with consuming contaminated deli meats, ready-to-eat products, and unpasteurized dairy. While healthy individuals are less likely to develop severe symptoms, the infection poses a significant risk to:

• Pregnant women
• Newborns
• Older adults (65+)
• Individuals with weakened immune systems

Listeria bacteria are particularly resilient, surviving refrigeration and freezing, which underscores the importance of proper food handling and preparation.

Recognising the Symptoms

Listeria infections can manifest differently based on the individual’s health and circumstances. Common symptoms include:

• Fever
• Chills
• Muscle aches
• Nausea
• Diarrhea

These symptoms can appear within a few days of consuming contaminated food but may take over a month to develop. If the infection spreads to the nervous system, more severe symptoms may occur, such as:

• Headache
• Stiff neck
• Confusion or altered alertness
• Loss of balance
• Seizures

Symptoms in Pregnant Women and Newborns

Pregnant women may experience mild flu-like symptoms, but the consequences for their babies can be severe, including stillbirth or life-threatening infections after birth. Symptoms in newborns might include:

• Lack of interest in feeding
• Irritability
• Fever
• Vomiting
• Breathing difficulties

Preventing Listeria Infection

While listeria bacteria are hardy, there are steps individuals can take to reduce the risk of infection:

• Practice Safe Food Handling: Wash hands, utensils, and surfaces thoroughly after handling raw foods.
• Avoid High-Risk Foods: Steer clear of unpasteurized dairy products, raw sprouts, and processed deli meats unless heated to steaming hot.
• Proper Storage: Keep perishable foods refrigerated below 40°F (4°C) and consume leftovers promptly.
• Stay Informed: Monitor recalls and advisories issued by health authorities.

Bottomline

The listeria outbreak linked to Yu Shang Food products serves as a stark reminder of the risks associated with foodborne illnesses. It highlights the need for stringent food safety practices and awareness of symptoms to ensure early diagnosis and treatment. If you or a loved one experience any symptoms associated with listeria, particularly after consuming ready-to-eat meat products, seek medical attention promptly.
