Multiple Choice

Refrigeration completely prevents growth and survival of Listeria in raw milk.

Explanation:
Refrigeration mainly slows how quickly Listeria can multiply rather than killing it. Listeria monocytogenes is capable of surviving cold temperatures, so while growth is limited, the bacteria remain viable. This means refrigeration can prevent noticeable growth but does not eliminate the organism. Therefore, the correct understanding is that refrigeration prevents growth but not survival. The idea that cold would kill Listeria or that both growth and survival are prevented isn’t accurate, since viable cells can persist at refrigeration temperatures.
