近日，据媒体报道，辽宁沈阳一家三口食用炒鸡蛋后集体中毒，“元凶”竟是被水洗后存放的鸡蛋，该事件引发热议。

不少人疑惑：鸡蛋为什么不能用水洗买回家后又该如何正确保存呢

A family in Shenyang, Liaoning province, suffered food poisoning after eating scrambled eggs, with the practice of washing the eggs before storage identified as a likely factor. The case has sparked widespread discussion.

湖北省农业科学院研究员、国家水禽体系蛋品加工岗位科学家孙静在接受记者采访时介绍， 鸡蛋蛋壳表面存在许多肉眼看不见的气孔，母鸡产蛋后，蛋壳会自然形成一层可溶于水的胶状保护膜 。

这层膜是鸡蛋天然的“防护服”，既能阻挡外界细菌、霉菌侵入蛋内，又能减少蛋内水分蒸发以保持新鲜度。

Sun Jing, a researcher at the Hubei Academy of Agricultural Sciences, told reporters that eggshells contain numerous pores that are invisible to the naked eye. After a hen lays an egg, a natural protective coating, known as the cuticle, forms on the shell. It helps prevent bacteria and mold from entering the egg while reducing moisture loss and preserving freshness.

如果用水清洗或浸泡，这层膜会直接被破坏，导致蛋壳气孔失去屏障 ，环境中的沙门氏菌等微生物便会趁虚而入，即使放入冰箱冷藏，变质过程也会显著加速。

Washing or soaking eggs can damage or remove this protective layer, leaving the pores more exposed. Salmonella and other microorganisms in the environment can then more easily enter the egg, increasing the risk of contamination and potentially shortening its shelf life even when refrigerated.

孙静建议， 市民 如果不慎清洗了鸡蛋，应尽快烹饪食用，或不超过三天内吃完，并配合冰箱冷藏、避免室温放置，其风险通常可控 。水洗后的鸡蛋不宜久存，即便在冰箱中，其他食物也可能引发交叉污染，对失去保护膜的鸡蛋产生更大的威胁。

对于表面带有污渍的蛋，孙静建议切勿用水冲洗， 最好用干布或干纸巾轻轻擦去掉浮垢 。若蛋壳上的粪污或血渍特别多，可能本身就不太新鲜，应尽量避免选购。

在储存方式上， 鸡蛋应大头朝上放置 ，以确保气室在上方，防止蛋黄贴近蛋壳，从而减少散黄变质的风险。在0至4摄氏度的冰箱保鲜层，普通新鲜鸡蛋存放一个月通常没有问题。

For storage, eggs should be placed with the larger end facing up so that the air cell remains at the top. This helps keep the yolk from pressing against the shell and may reduce the risk of yolk rupture and spoilage. When stored in a refrigerator at 0 to 4 C, fresh eggs can generally be kept for an extended period, although the exact shelf life varies depending on storage conditions and the eggs' freshness.

鸡蛋很容易被各种物质污染，怎样才能正确地保存鸡蛋，安全食用呢

冷冻会使蛋白质性质改变，造成蛋黄凝固，还有可能撑破蛋壳。

买回来的鸡蛋若表面有污渍，可以放入保鲜袋或盒中存放，烹饪之前再把表面的污垢冲洗掉。

鸡蛋外壳上有很多致病菌和污垢，不要将“裸蛋”直接放进冰箱，应隔离收纳后再放入，避免和其他食物造成交叉污染。

Eggs should not be frozen in their shells, as freezing can cause the shells to crack and alter the texture of the yolk and egg white. Avoid rinsing eggs before storage. If the shell is dirty, place the egg in a sealed bag or container and wash it immediately before cooking. Eggs should also be kept separate from other foods in the refrigerator, as their shells may carry pathogens and dirt. Proper separation can help prevent cross-contamination.

最后，要注意鸡蛋不能无限期地存放下去。一般来说，保存1至2周的鸡蛋食用是没有问题的，且口感、营养俱佳；最长不要超过1个月，否则不仅营养成分会大量流失，鸡蛋还会变成“坏蛋”。
