How long can eggs be kept at a constant temperature

Eggs can generally be stored for 7-10 days in a constant temperature environment, and the specific time is affected by factors such as storage temperature, eggshell integrity, cleanliness, placement method, and environmental humidity. When eggs are stored in a constant temperature environment, temperature is the key factor. When the room temperature is about 25 degrees Celsius, the shelf life of eggs usually does not exceed 10 days, as high temperatures can accelerate the evaporation of water and bacterial growth inside the eggs. A complete and crack free eggshell can effectively block external microorganisms and prolong storage time. The natural protective film on the surface of unwashed eggs before storage can inhibit bacterial invasion, but eggs contaminated with feces or dirt need to be cleaned and refrigerated. Placing the egg yolk upright in the center reduces the contact area of the gas chamber, which is more conducive to preservation than placing it flat. Low environmental humidity can cause the pores of eggshells to enlarge, increasing the risk of water loss. If the temperature fluctuation of the egg storage environment is large or exceeds 30 degrees Celsius, the growth rate of bacteria will accelerate, and it may spoil in 3-5 days. Fine cracks on eggshells can significantly shorten their shelf life, and pathogens such as Salmonella can easily invade through the cracks. Washed eggs lose their cuticle protection and can only be stored at room temperature for about 3 days. High temperature and high humidity environments can promote mold growth on the surface of eggshells, producing mold spots and penetrating into the egg. Repeatedly taking eggs from the refrigerator can cause condensation water to adhere, which can damage the eggshell barrier function.

It is recommended to refrigerate eggs to extend their shelf life, and they can be stored for 3-5 weeks under refrigeration conditions. Keep the eggshells dry and clean during storage, and place them upright with the blunt end facing upwards. Before consumption, check if the eggshells are intact. Immerse the eggs in water and observe their rise and fall to determine freshness. Eggs that sink to the bottom are fresher. In summer or humid environments, the storage time at room temperature should be shortened as much as possible. Before cooking, heat the egg yolk thoroughly until it solidifies to ensure food safety. Special populations such as pregnant women, the elderly, and immunocompromised individuals should avoid consuming eggs that have been stored for an extended period or stored improperly.
