Listeria infection, also known as listeriosis, is caused by the bacteria Listeria monocytogenes. While consuming food contaminated with listeria isn't usually serious for most healthy people, it can lead to serious illness, especially for pregnant individuals and those with weakened immune systems. According to the Centers for Disease Control and Prevention (CDC), listeria is the third leading cause of death from foodborne illness in the US, killing about 260 people a year.
