Listeria is a type of bacteria commonly found in soil, water, and some animals, including poultry and cattle. It’s particularly noteworthy because it can contaminate food and cause serious illness, especially in pregnant women, newborns, the elderly, and individuals with weakened immune systems.
What is Listeriosis?
Listeriosis is an infection caused by consuming food contaminated with Listeria monocytogenes. Unlike many other foodborne pathogens, Listeria can thrive in cold environments, such as your refrigerator, making it a unique threat in terms of food safety.
Symptoms of Listeriosis
Symptoms can vary widely depending on the individual and the severity of the infection. Common symptoms include:
- Fever
- Muscle aches
- Nausea
- Diarrhea
In severe cases, the infection can spread to the nervous system, causing symptoms such as headache, stiff neck, confusion, loss of balance, or convulsions. For more detailed information on symptoms and when to seek medical help, check out our health section.
High-Risk Foods
Listeria is commonly associated with certain high-risk foods, including:
- Unpasteurized dairy products
- Deli meats and hot dogs
- Soft cheeses (e.g., queso fresco, feta, brie)
- Smoked seafood

Prevention and Treatment
Preventing listeriosis involves proper food handling and storage practices. Here are some key steps:
- Refrigeration: Keep your refrigerator at or below 40°F (4°C) and use foods before their expiration dates.
- Cooking: Cook meat thoroughly and avoid cross-contamination with raw meats and vegetables.
- Cleaning: Wash hands, utensils, and cutting boards with hot, soapy water after handling raw foods.
If you suspect you have listeriosis, it’s important to seek medical attention promptly. Antibiotics can treat the infection, but early detection is crucial, especially for high-risk groups.
