(Reuters) - On
the windswept prairies of the Oklahoma Panhandle, the hog barns of
Prestage Farms are lined up like military barracks. The 20,000-sow
operation near the Texas border stands at the front lines of a
months-long battle to contain a virus that has already killed some 1.3
million hogs in the United States.
Since June, when Porcine
Epidemic Diarrhea virus, or PEDv, first hit, Prestage workers have
quarantined the area, scrubbed vehicles and sprayed buildings with
antiseptic. But those precautions have not stopped a virus that can kill
80 percent of piglets that contract it.
