7. Debunking Common Myths About Food Poisoning

There are many misconceptions about food poisoning. Let’s set the record straight:

7.1. Myth: “The 5-Second Rule”

Reality: Bacteria can attach to food almost instantly. Dropping food on the floor, regardless of how quickly you pick it up, exposes it to potential contamination.

7.2. Myth: “If It Smells Okay, It’s Safe to Eat”

Reality: Many harmful bacteria don’t affect the smell, taste, or appearance of food. Trust your eyes and refrigeration dates more than your nose.

7.3. Myth: “Freezing Kills Bacteria”

Reality: Freezing only stops bacterial growth; it doesn’t kill the bacteria. When food thaws, bacteria can become active again.

7.4. Myth: “Alcohol Kills Bacteria in Food”

Reality: While alcohol can kill some bacteria on surfaces, it’s not effective at killing bacteria in food. The alcohol content in most foods isn’t high enough to sanitize them.

7.5. Myth: “Only Mayonnaise Causes Food Poisoning”

Reality: While mayonnaise-based salads can support bacterial growth if not properly refrigerated, many other foods can cause food poisoning. The key is to keep perishable foods at safe temperatures.
