Dr. Benjamin Silk presents key information on listeriosis in the aftermath of the large 2011 outbreak.
How is Listeriosis Treated?
- Listeriosis is treated with antibiotics. A person in a high-risk category (pregnant woman and their newborns, older adults, and people with weakened immune systems) who experiences fever and other non-specific symptoms, such as fatigue and aches, within 2 months of eating contaminated food should seek medical care and tell the physician or health care provider about eating the contaminated food.
- If a person has eaten food contaminated with Listeria and does not have any symptoms, most experts believe that no tests or treatment are needed, even for persons at high risk for listeriosis.
Even with prompt treatment, some listeriosis cases result in death. This is particularly likely in older adults and in persons with other serious medical problems.
