*Listeria monocytogenes* was first identified in animals in the early 20th century and later recognized as a significant human pathogen. The bacterium was named after Joseph Lister, a pioneer in antiseptic surgery. Large foodborne outbreaks in the latter half of the 20th century significantly raised public health awareness regarding Listeriosis.
Listeriosis is primarily transmitted through the consumption of food contaminated with *Listeria monocytogenes*. Common sources include raw or undercooked meats, unpasteurized dairy products, soft cheeses, deli meats, and raw produce. Pregnant women can also transmit the bacteria to their unborn or newborn babies.
