The US FDA says that samples of milk taken from grocery stores across the US have tested

positive for remnants of the bird flu virus that has infected dairy cows.

But the agency says it's confident the milk you are buying is safe.

Officials also say the finding suggests the virus is spreading more

prevalently among dairy herds than previously thought.

To help slow that spread, the USDA announced today

that dairy cattle must now be tested for the virus

before moving to a new state.

We're joined now by Dr. Jennifer Nuzzo, a director of the Pandemic Center at

Brown University. Thank you for being with us. So let's start with the latest update. Particles

of this virus found in commercial pasteurized milk.

How concern should the everyday consumer be?

I don't have any reason to be concerned at this point.

Finding evidence of genetic material, which

is what the test results told us, by itself is not alarming.

In order to know if the virus will infect us, we have to do a different kind of test and this test was not that.

They're actually undergoing those tests now.

But I don't have any reason to think that we will be harmed

because we use pasteurization and I have no reason to think that the H5N1 virus is any different from all the other

Pathogens that we think could be in milk pasturization doesn't remove the genetic material of those pathogens, but it changes the pathogens

and either kills or it activates them so that they can't infect us.

And I fully expect that that's what the test results will say and just more reason to you know
