That's because certain strains of E.coli when they contaminate food can cause abdominal cramping, serious intestinal problems, fever or kidney failure.
And estimated 265,000 Americans get infected from this every year.
A dangerous strain of E.coli might have made its way in the beef products sold in nine states.
11 people are thought to have gotten sick from it, ten of them ate at restaurants that received contaminated meat.
The U.S. Department of Agriculture says 1.8 million pounds of ground beef have been recalled.
An official says it's currently being removed from store shelves, but some of it has already sold.
Dr. Sanjay Gupta tells, you what to look out for.
If you have any ground beef in your freezer that says 2574B, that's the lot number that's of concern.
You want to throw that out.
Don't take any chances.
E.coli is a particularly-the strains of it is a particularly nasty player.
Just 100 cells can make somebody ill, and if left untouched it will double the number every 15 to 20 minutes.
So, you can get to billions of cells, you know, fairly quickly.
And that's why people are really, really-being very cautious about this.
Don't take any chances.
Even if you don't have this ground beef, even you've thrown it away, it's Memorial Day weekend.
If you are grilling, use a thermometer.
That could be the best advice I give you all weekend.
Use a thermometer, take a look at the numbers there.
That's what you're going to be shooting for.
I use the thermometer.
It helps keep me and my family safe.
You should do the same thing.
这是因为某些大肠杆菌的菌株在感染食物后，会引起腹部痉挛、严重肠道问题，高热或者肾衰竭。
据估计有26万5千美国人每年感染大肠杆菌。
一种危险的菌株可能在牛肉产品中蔓延，美国的九个州都售卖此产品。
11人因此生病，其中有10人是在售卖感染肉品的餐馆就餐的。
美国农业部说有1百80万磅的牛肉末被召回。
一位官员透露，感染肉类正在从商店的货架撤回，但是其中的一些已经被买走。
Sanjay Gupta医生告诉你，你需要注意什么。
如果你在冰箱里发现牛肉末，并且上面写着2574B，那么这个货号就是感染的牛肉。
你必须将它仍走。
不要冒任何险。
大肠杆菌是一种特殊的细菌，非常调皮。
仅仅100个细胞就能让机体生病，如果不动它，它将在15到20分钟内增殖一倍。
所以，你将获得几千万的细胞，你知道，速度可真够快的。
这就是问什么人们很关心它的原因。
不要有任何侥幸心理。
如果你没有这个牛肉末，即使你已经仍走了，这是纪念日周末。
如果你已经发热，使用体温计。
这就是我在周末能给你的最好建议。
记得使用体温计，他能帮助我和我的家人。
你应该也这样做。
