Yeah, turns out, the so-called 5-second rule is as disgusting as we all thought.
是啊，原来，所谓的5秒规则和我们想的一样恶心。
According to a new study out this week, no matter how fast you pick up food that's been dropped on the ground, you can still pick up dangerous germs along with it.
本周根据一项新的研究，无论你如何快速捡起被扔在地上的食物，上面仍然有危险的细菌。
To finally debunk the 5-second rule once and for all, researchers contaminated four surfaces with bacteria.
为了彻底揭穿这5秒规则，研究人员用细菌污染四个表面。
They then dropped four different types of food onto those surfaces, watermelon, bread, buttered bread and gummy candy.
然后他们把四种不同类型的食物丢在这些表面上，分别是西瓜，面包，奶油面包和软糖。
The scientists found, generally speaking, the 5-second rule has some truth to it. the longer the food sat there, the more bacteria accumulated on it.
科学家们发现，一般而言5秒规则也有一定道理。食物与地面接触的时间越长，上面的细菌就越多。
But in some cases, the bacteria made its way onto the food in less than 1 second, and no food was left completely uncontaminated.
但在某些情况下，细菌不到一秒就进入了食物，没有食物是完全无污染的。
As one of the study's authors said in a statement, "Bacteria can contaminate instantaneously."
研究的作者之一在一份声明中表示，细菌可以瞬间污染食物。
For the record, watermelon picked up the most bacteria, thanks to its moisture. And the gummy candy got the least.
试验结果中，西瓜沾有最多的细菌，因为它水分多。软糖上的细菌最少。
So next time you drop food on the floor, you might want to think about the bacteria crawling on it before you take a big bite. Just saying.
所以下一次你把食物丢在地上，在大咬一口前可能要想想上面爬着的细菌。说说而已。
