Bacteria have never had a greater role in cultured dairy products than today. It used to be that companies purchased cultures only for the types of flavors and rate of acid production needed, but now they can add texture development and health benefits to the list.
The shelf life of milk is the number of days it retains a desirable taste flavor when held at refrigerated temperatures. Temperature is critical to maximize shelf life.

Listeria monocytogenes (L. mono)is a gram-positive bacterium and a specific member of the Listeria family. It is capable of causing severe illness and even death. The mortality rate from L. monoin susceptible populations is one of the highest of any known food pathogen. Individuals with compromised immune systems are particularly vulnerable.
