Listeria monocytogenes is one of the six species belonging to the genus Listeria.

Outbreaks of listeriosis are caused by L. monocytogenes. The outbreaks are seasonal and linked to silage feeding.

Listeria monocytogenes replicates in poor quality silage, where the pH exceeds 5.5.

Animals are highly susceptible during pregnancy due to lowered cell-mediated immunity.
