We've all heard them. "It smells fine." "Just cut the mold off." At RupIELTS Institute, our instructors hear these myths in almost every Food Safe Level 1 class. While some are harmless, others are downright dangerous. Let's set the record straight using accepted food science.
⏱️ Myth #1: The "5 Second Rule"
The belief: If you drop food on the floor and pick it up within 5 seconds, germs don't have time to jump onto it.
✅ The Truth:
Bacteria transfer instantly upon contact. Wet food picks up more bacteria than dry food, but 1 second is enough to contaminate anything. When in doubt, throw it out.
❄️ Myth #2: Freezing Kills Bacteria
The belief: If meat is getting old, just freeze it to kill the germs.
✅ The Truth:
Freezing does not kill most bacteria; it just puts them to sleep (dormant). As soon as you thaw the food, the bacteria wake up and start multiplying again exactly where they left off.
👃 Myth #3: The "Sniff Test" Works
The belief: If milk or leftovers don't smell bad, they are safe to eat.
✅ The Truth:
The bacteria that cause food poisoning (pathogens like E. coli) are odorless, colorless, and tasteless. Spoilage bacteria make food smell bad, but they rarely make you sick. Pathogens are the silent killers you can't smell.
🥩 Myth #4: A Rare Burger is Safe Like a Rare Steak
The belief: I eat my steak medium-rare, so my burger is fine too.
✅ The Truth:
Bacteria live on the surface of meat. Searing a steak kills the surface bacteria. When meat is ground into burger, the surface bacteria are mixed throughout the entire patty. A burger must be cooked all the way through (71°C) to be safe.
