Habitat

The listeria bacteria’s natural habitat is in sewage, soil, water, vegetation, food processing plants, and human and animal feces. Listeria is found all over the world because all these habitats are present throughout each continent.  It is also unique because it is able to survive harsh conditions such as heat, high pH levels, and salt levels, which many bacteria are not able to do. It has the capability to survive freezing and refrigeration which is why it is dangerous to humans.
