In many parts of the world, eggs are a staple food item in people’s diets. Whether they are fried, boiled, or used as an ingredient in various dishes, eggs are versatile and nutritious. However, a common question that arises is whether eggs need to be refrigerated.
The answer to this question may vary depending on where you live. In some countries, it is common practice to store eggs at room temperature, while in others, refrigeration is considered necessary. The reason for this difference lies in the way eggs are processed and treated before they reach the consumer.
In countries where eggs are washed and sanitized before they are sold, refrigeration is recommended. This is because the washing process removes the natural protective coating on the eggshell, making it more susceptible to contamination from harmful bacteria. In contrast, in countries where eggs are not washed or sanitized, the natural protective coating remains intact, and refrigeration may not be necessary.
It is important to note that regardless of whether you choose to refrigerate your eggs or not, proper handling and storage are essential to maintain their freshness and safety. Eggs should be stored away from strong-smelling foods to prevent them from absorbing odors, and they should always be cooked thoroughly before consumption to reduce the risk of foodborne illnesses.
