A family of three in Xi'an, Northwest China's Shaanxi province, has been diagnosed with gastroenteritis after consuming watermelon placed overnight in the fridge, all developing symptoms such as nausea, vomiting and diarrhea, according to Bailu Video on Tuesday. The child was even rushed to Xi'an Children's Hospital to deal with severe conditions of kidney failure.
Is it safe to eat refrigerated watermelon? The topic has once again taken over social media platforms.
那么冰西瓜到底能不能吃?怎么吃才安全呢?
隔夜冰西瓜一口吃下8400个细菌?
其实西瓜是否隔夜并不是主要问题,关键在于是否有致病菌。
一个好的、完整的西瓜,内部基本上是无菌的。但切开的西瓜没有了瓜皮的保护,就算是放在冰箱中冷藏,菌落数也依然会上升。
According to a study on bacteria formed in watermelon overnight, the researchers cut the watermelon with clean, specialized knives and household butcher knives. Pieces of watermelon were divided into experimental and control groups. After that, the watermelon was wrapped in cling film to preserve freshness and placed in the refrigerator for 24 hours.
The results showed that watermelons cut with special knives contained only 45 bacteria per 25 grams, while watermelons cut with household knives contained 8400 bacteria per 25 grams.
This experiment proved that watermelons cut with clean knives will not form deadly bacteria when stored in the refrigerator.
还有网友表示,可以将隔夜冰西瓜表面切去一层再吃,这样就不会把细菌吃到肚子里了。
对此医生表示,这种方法也会存在一定安全隐患。
如果没有被致病菌污染,即使不切掉表层,也完全是可以放心吃的。但如果已经被致病菌污染了,即使你切掉西瓜表层,还是可能使人生病。
怎样安全吃瓜?
最后,送上一些卫生小Tips,让你大夏天安全吃瓜。
For whole watermelons, run cold water over watermelon. Wipe the outside to remove any dirt or residue and pat with a clean, dry towel or paper towels.
When buying pre-cut or packaged watermelon, choose only those refrigerated or surrounded by ice.
Cut watermelons with clean knives.
Don't let watermelon pieces sit out at room temperature for longer than three hours.
For cut watermelons, wrap tightly in plastic, or in an airtight container and refrigerate.
To be eaten within 24 hours (the sooner you eat it, the better!)
Keep fresh produce separate from raw meat, poultry, and seafood products.
最后,更推荐大家买小一点的瓜,尽量一次吃完哦!
