The Benefit Of Putting A Coin In Your Freezer Before Leaving The House
By JACQUELINE DELIBES
TikTok user @thewannabeprepper.com suggests placing a coin in the fridge to know if there was a power outage while you were out, which might have led to the food going bad.
Thawed-out and refrozen food may look edible, but USDA guidelines state that food unrefrigerated for over two hours allows bacteria to grow and causes illness if consumed.
Freeze a cup of water and place a coin on the top. If you return and find it has sunk halfway, it likely melted partially, rebooted, and froze back up, meaning the food is safe.
However, if your coin is at the bottom of the glass, toss the food, as this indicates that the freezer had unfroze and reached room temperature for a significant amount of time.
