Question: Can Germs Be Killed By Freezing?

Does freezing kill viruses and bacteria?

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..

Do germs spread faster in hot or cold?

In dry air, the droplets remain smaller and lighter, allowing them to spread further. However, in more humid conditions, droplets can be larger and heavier, making them fall to the ground faster. On the other hand, hot temperatures are more likely to kill viral germs.

Does freezing kill bacteria on clothes?

Why do hospitals keep it so cold?

Hospitals combat bacteria growth with cold temperatures. Keeping cold temperatures help slow bacterial and viral growth because bacteria and viruses thrive in warm temperatures. Operating rooms are usually the coldest areas in a hospital to keep the risk of infection at a minimum.
