A fatal swine disease is striking the nation's hog industry. Porcine Epidemic Diarrhea Virus or PED is usually deadly for baby pigs. Its symptoms resemble dysentery, and it's spread through bodily secretions. Tom Ray, director of Livestock Health Programs for the state department of Agriculture and Consumer Services, says so far, there have been only four confirmed cases in North Carolina. He expects the impact for farmers and the state's economy to be significant.
