For this reason, you should always put a coin in your freezer

Disaster and Emergency Kit

In regions where earthquakes, floods, or even hurricanes occur, power supply may be cut off for a considerable time. A coin-in-the-freezer trick provides the most workable method of knowing what food items consumed after such a disaster are safe. Because many freezers turn on automatically when power is restrored, nothing inside a freezer would have thawed, but you can never know which did.

In disaster situations, fresh food may not be accessible, and knowing what is safe to eat becomes even more important. This hack will help you avoid eating spoiled food and staying healthy during challenging times.
