This is John Batchelag. My colleague Jim McTagg in Lancaster County reports

Canadian snow geese dead in Allentown near Lancaster County.

Why this is significant, Jim explains, as more Canadian snow geese are on the way.

And the cause of death of the first lot is bird flu.

Much fear about bird flu jumping to the local chicken population

and from there to the cattle and the rest of the agricultural cycle,

including human beings.

Bird flu in Allentown, Pennsylvania, near Lancaster County, Pennsylvania.

Jim McTague reporting, much more of this tonight.

The bird flu.

I mean, the people in Pennsylvania are extremely worried about the bird flu.

I don't think the general public is alarmed yet, but what we have is

there's a bird, there's a flu among wild birds, and some of it has spread to cattle. And

Lancaster County is the largest egg producing county in Pennsylvania. And Pennsylvania is the fourth largest egg producer

in the country, and Lancaster County is also the biggest milk producer. So what happened

this week is in Allentown, which is only 60 miles away, they've discovered 200 dead snow geese. They were all killed by the

bird flu. Now, why that is important is in February, just north of us in Lebanon County at a reserve called Middle Creek, it's a reservoir,

we get visited every year by between 70,000 and 100,000 snow geese. It's one of the most

beautiful sites you can see around here.

And there's a huge concern that those new snow geese are going to infect local flocks of chicken and that the virus will jump into cattle, which would just have a devastating impact on Lancaster County's economy.
