How long does Listeria monocytogenes last?
Signs and Symptoms of Listeria Infection In many healthy individuals, consuming the bacteria may cause no symptoms at all. Even if a healthy person does experience symptoms, these tend to go away on their own, though listeria-associated diarrhea can last up to five days.
Why Listeria monocytogenes is a problem in foods?
L. monocytogenes is unusual because it can grow at refrigerator temperatures where most other foodborne bacteria do not. When eaten, it may cause listeriosis, an illness to which pregnant women and their unborn children are very susceptible.
What are the symptoms of listeria monocytogenes?
The symptoms vary with the infected person:
- Higher-risk people other than pregnant women: Symptoms can include fever, muscle aches, headache, stiff neck, confusion, loss of balance, and convulsions.
- Pregnant women: Pregnant women typically experience only fever, and other non-specific symptoms like chills and headache.
What causes listeria outbreaks?
Listeriosis is caused by Listeria, a type of bacteria that is commonly found in water, soil, and feces. Humans are infected when they consume foods that harbor the bacteria. The most common foods to cause listeriosis outbreaks are deli meats and unpasteurized dairy products.
Does cooking food kill Listeria?
Listeria is killed by pasteurization and cooking; however, in some ready-to-eat foods, such as hot dogs and deli meats, contamination may occur after factory cooking but before packaging. Unlike most bacteria, Listeria can grow and multiply in some foods in the refrigerator.
What are the long-term effects of Listeria?
A Listeria infection can lead to meningitis, an inflammation of the membranes surrounding the brain. If a newborn infant is infected with Listeria, long-term consequences may include mental retardation, seizures, paralysis, blindness, or deafness.
Why does deli meat have Listeria?
Deli meat can harbor listeria monocytogenes because it can be cross-contaminated during processing. Deli meat and other processed meats go through extensive processing and handling during production, which can increase the opportunities for cross-contamination.
How do doctors treat Listeria infection?
In some cases, samples of urine or spinal fluid will be tested as well. Treatment of listeria infection varies, depending on the severity of the signs and symptoms. Most people with mild symptoms require no treatment. More-serious infections can be treated with antibiotics.
