What are the risks of consuming an egg that has been left out of the refrigerator for too long while boiling it?

 Fresh shell eggs may contain bacteria. When cooking eggs, be sure to heat them to a safe internal temperature above 160°F (71°C) to kill any bacteria that may be present.

According to nutritionists, hard-boiled eggs are considered perishable items. At room temperature of 77°F(25°C), hard-boiled eggs can only be stored for up to one day.

Facts have proved that the low temperature of the refrigerator will greatly reduce the activity of bacteria, thus effectively extending the shelf life of food.

However, bacteria and microbes are so adaptable that they can still reproduce in the refrigerator.

According to The American Egg Board, Hard-boiled Eggs Have a Shelf Life of One Week in the Refrigerator.

Experience has shown that the quality of hard-boiled eggs also begins to decline if refrigerated for longer

How can watermelons be kept fresh for a long time?

 The delicious and juicy red flesh of watermelon is rich in vitamins, minerals and lycopene, which is very beneficial to health.

A complete watermelon can be stored for about 2 weeks in the refrigerator, while it can only be stored for about 1 week at room temperature.

To store a cut watermelon, wrap the cut side tightly with plastic wrap and place in the refrigerator.

Plastic wrap can be tightly attached to the cut watermelon to forming a seal against outside odors, air and bacteria.

Practice has proved that if the cut watermelon is wrapped in plastic wrap and placed in the refrigerator, its appearance, taste and freshness will not change within 4 to 5 days.

In fact, the combined effect of plastic wrap and low temperature can effectively prolong the shelf-life of watermelon and keep the watermelon's moisture and locking the freshness.
