Dr. Howard Hill-National Pork Producers Council:
We know some of the ways that it was spread, lateral transmission from one farm to the other.
There may be a feed issue.
The Canadians have shown it and we've had some cases where it's been shown to be in feed and producers are learning how to control that with how the feed is manufactured and what ingredients they're using and that sort of thing.
As far as how widespread, we have pretty good evidence that there's about two and a half million sows that have been affected and, with two and a half million pigs, each sow is estimated to lose about 2.7 pigs if she has the infection so you multiply that together and you come up with about seven million pigs that are lost.
But that doesn't mean that we're going to be short that much pork because a couple of things have happened.
One is PRRS was very very mild this last winter and that may be because we had some herds shut down.
We weren't introducing animals because of PED.
The other thing producers have done to compensate for the loss of pigs is they've increased the weights.
If a pork producer was selling at say 270 to 275 now they're selling at 280 to 285 so we've picked up a lot of weight there so it's not going to be a tremendous shortage of pork.
Dr. Hill acknowledges PED has affected the market to some extent.
He notes we've seen record prices and record cutout values so far this spring.
