You can also get sick if its juices leak in the refrigerator or get on kitchen surfaces and then get on something you eat raw, such as salad.
Can Salmonella grow in the refrigerator? Pathogenic bacteria can grow rapidly in the “Danger Zone,” the temperature range between 40 °F and 140 °F. Because they do not generally affect the taste, smell, or appearance of a food, one cannot tell that a pathogen is present. Spoilage bacteria can grow at cold temperatures, such as in the refrigerator.

How does cross contamination occur in the refrigerator?
Cross contamination occurs when germs from one food item spread to another food item. This could happen directly, like if a piece of raw meat drips on or touches another food. It can also happen indirectly, like if you use the same knife to cut raw meat as you do to chop lettuce, without washing the knife in between.

Why do you have to keep cultures inside the refrigerator?
The goal of preserving the cultures is to slow that death rate so that when the culture is revisited, some of the cells are still viable and available for culturing. The reasons the cells die can be numerous, but in every instance are based on the inherent chemistry of the cells and their environment.
Why would bacteria not multiply in a freezer?
Freezing does not kill germs and bacteria. Instead, it essentially puts them into hibernation. They are inactive while the food is frozen and will “wake up” as soon as the food thaws. And as the food thaws, so will the moisture, which means the bacteria will have the moisture it needs to survive.
Why does bacteria revive after freezing?
Under the microscope – Freezing
The low temperatures cause a delay in chemical reactions in food, which results in slowing down or causing bacteria to become dormant. The bacteria are still alive but they stop growing or producing toxins so in effect pausing reactions.
Do most bacteria become active when food defrosted?
Freezing does not kill harmful bacteria in food.
When you take food out of the freezer or leave frozen food out for too long before putting it away, the thawing process begins, and it starts to defrost. Once this happens, the harmful bacteria in the food ‘awaken‘, and they become active.
