I drop something on the floor 52 rule right you can still eat it.

Apparently food that falls on the floor is not safe to -- even if it's been there for just -- Especially if it falls into the dogs well.

Researchers at -- a state university found that plenty of time for germs to to attach themselves so the lesson here.

If you see an order -- French Fries somewhere on the ground -- restrain yourself.

Doctor -- Cheatham is with us from Columbia University -- and I don't know if anybody ever thought this 52 -- with real effect but it -- -- I think people may have -- say shut this is a crazy Sunday.

And just to put and sent a spot except in the -- -- They used three baby carrots that aspect of the study was that they used one Cara as a control Karen Hughes and these three baby carrots -- Into -- brands and they put them on four different -- says.

The -- to -- the sink.

A -- -- and a copy two suspects.

And gas while they check if there's baby carrots from Phil.

-- five seconds they picked up bacteria.

That was the -- it.

Well I'm so proud of them bit.

That's and the -- -- it or not I don't have a Ph.D.

in the microbiology.

Of carrots that probably somebody from -- Diego state investment.

Probably in the countertop was is worse than the carpet it lost upstate -- and that was kind of a surprise that people often think of the Phil would be -- the caps tough.

Well you -- the thing about our counter tops is we can put all kinds of food on our counter tops and we know cleaner count exceptionally well it's just.

Breeding ground for especially if -- cat walks on the -- can lose the lesson here is don't have a cat.

-- but you know what I'm saying -- they've been in the litter box who wouldn't play well -- It the study was kind of bit tongue and say -- well being CDC website -- to get some very serious and useful points at ground.

-- safeties if you go to CDC dot gov slash sports -- safe day.

This information -- back keeping your account it's not seen the back half to capacity -- -- and that she four point eight million people.

-- -- -- Disease.

Again thoughts -- -- you know and 3000 people dying from three poisoning and there in the US.

A lot of upset -- that are never diagnosed as that but a lot of -- you know that that that yearly fiscal may not be doing you too much good either.

A medical group in Great Britain has published a large scale study that shows that general medical check up to do not affect mortality.

In other words is going to the doctor every year doesn't necessarily help people live any longer.

One of the doctors involved in the study admits the results seem to go against commonly held beliefs namely that regular checkups lead early diagnosis of -- diseases.

But the researchers say the results so the check ups can still be beneficial if doctors tailor them to patients instead of just doing a bunch of unnecessary tests we'll look.

You're going to get your heart check your cholesterol check your blood pressure this seems worthwhile to me the -- wanna do is just completely not in an annual check up with the insurance pays for.

Well that's right shot from the study may be -- -- -- and having numbers are in the study is anything reported today.

But the key issues that we still need to tell patients that blood pressure -- -- -- -- -- -- -- -- -- -- -- And the studies may be looking -- -- -- -- task and that is not walk this kind of screening as brown.

Blood tests will not pick up significant -- -- the manatees that things like blood pressure controlled thought back to control I saw -- -- Saint John and if you're not -- to get sick often so you don't go to the doctor often -- there'd be no reason for you to have your your cholesterol checked your blood pressure checked and that's where it seems to me and it's.

But -- -- as you get older isn't it normal sensible to do that.

It is cents a barrel on the -- guidelines -- specific patient age brackets a different countries have different guidelines.

So don't need to care that they fall on the floor and go to the doctor once a year no matter what that means that the studies -- -- -- at night I could pick it and didn't think it doctor.
