FILE - In this July 9, 2009 file photo Dr. Craig Rowles stands with hogs in one of his Carroll, Iowa, hog buildings. The farmer and longtime veterinarian did all he could to prevent porcine epidemic diarrhea from spreading to his farm, but despite his best efforts the deadly diarrhea attacked in November 2013, killing 13,000 animals in a matter of weeks. PED, a virus never before seen in the U.S. has killed millions of pigs in less than a year, and with little known about how it spreads or how to stop it, it’s threatening pork production and pushing up prices by 10 percent or more.
