US pig industry battling PEDV spread:Porcine epidemic disease virus poses an economic threat to the 68,300 hog farms that make up the US pig herd

摘要

Porcine epidemic disease virus (PEDV), a disease fatal to newborn piglets and unfamiliar in the U.S., is spreading through the Midwest at an alarming rate, with 300 confirmed cases in 16 states since its arrival in April 2013. PEDV has been in the global pig industry for decades, with reports from Great Britain in 1972 and from China in 1982. Yet, with no previous exposure in the U.S., PEDV poses an economic threat to the 68,300 hog farms that make up the U.S. pig herd.
