Etymology
Origin of listeria
Explanation
Listeria is a bacteria that can contaminate food and make people very sick. In pregnant and elderly people, the infection caused by listeria is particularly dangerous. Infants and people with compromised immune systems are also especially vulnerable to listeriosis, the infection that the listeria bacteria can cause. The most serious cases can lead to blood infection and meningitis. Hand washing and thoroughly cooking raw food can help prevent the growth of listeria, and susceptible people can stay safe by avoiding certain foods, including soft cheese and raw hot dogs. Listeria is named in honor of the groundbreaking early 20th-century bacteriologist Joseph Lister.
