Refrigerators serve the important purpose of preserving perishable food items in our daily lives. Unfortunately, we often face minor mishaps such as power outages, power surges, or malfunctions in our refrigerators, which can lead to spoilage of the stored food.
After power is restored, it is important to be cautious about consuming the food in your refrigerator. While it may appear normal, the chances are that these foods may have been contaminated by harmful bacteria or microorganisms. Therefore, it is crucial to ensure the safety of these items before consuming them.

One method for evaluating food quality involves placing a coin in a cup of water and refrigerating it.
To address this issue, a practical solution involves employing a coin as a helpful tool. The process is straightforward: begin by filling a cup with water and placing it in the freezer. Once the water has solidified into ice, remove the coin positioned on the surface and reinsert it within the cup.
Safety Indicator:
The safety of the preserved food can be determined by the condition of the coin in the cup. There are three possible situations:
- If the coin is completely submerged in the food, it indicates that the food is no longer safe to consume.
- If the coin is partially submerged, it suggests that the food may still be safe, but caution is advised.
- If the coin is fully visible and not submerged at all, it indicates that the food is safe to consume.
When conducting a check, it is important to observe whether the coin is still floating on the water’s surface. This indicates that the refrigerator is functioning properly, with no power outages or surges. Additionally, it ensures that the food stored inside remains safe for consumption.

Coin Condition
If you find that a coin is positioned midway between the waters, it indicates that your refrigerator has encountered power interruptions and has temporarily ceased functioning. Although it might still be deemed safe for use, it is essential to conduct a thorough inspection before resuming regular use.
If the coin sinks to the bottom of the cup, it indicates that the refrigerator has been inoperative for an extended period. As a result, the ice in the freezer has melted completely, causing the new coin to sink as well. In all likelihood, the food stored in the refrigerator has already spoiled, as it has not been adequately preserved at temperatures above freezing.
When in doubt about the safety of preserved food, it is always best to err on the side of caution and discard it. Staying healthy should be our top priority.
