Fact: While it’s true that putting very hot food directly into the refrigerator can raise the internal temperature and potentially affect other foods, it’s more important to cool the food quickly to prevent bacterial growth. Divide hot food into smaller portions or shallow containers to help it cool faster, and refrigerate it as soon as it stops steaming.

7.2. Myth: Freezing Food Kills All Bacteria

Fact: Freezing food slows down the growth of bacteria, but it doesn’t kill them. When the food thaws, the bacteria can become active again. That’s why it’s important to handle thawed food properly and cook it to the correct internal temperature.

7.3. Myth: If Food Looks and Smells Okay, It’s Safe to Eat

Fact: Many harmful bacteria don’t affect the appearance, smell, or taste of food. It’s impossible to tell if food is safe to eat just by looking or smelling it. Always follow recommended storage times and cooking temperatures.

7.4. Myth: You Can Refreeze Thawed Food Safely

Fact: Refreezing thawed food can increase the risk of food poisoning. When food thaws, bacteria can multiply rapidly. Refreezing it doesn’t kill the bacteria, and it can affect the quality and texture of the food. As a general rule, avoid refreezing thawed food, especially raw meats.

7.5. Myth: All Food Should Be Stored in the Refrigerator

Fact: Some foods, like potatoes, onions, and bread, are best stored at room temperature. Refrigerating these foods can affect their texture and flavor. Always store food according to recommended guidelines.
