Yet another threat to our food supply.
Killer Pig Virus Wipes Out More Than 10 Percent Of Nation's Hogs, Causing Spike In Pork Prices

The killer stalking U.S. hog farms is known as PEDv, a malady that in less than a year has wiped out more than 10 percent of the nation's pig population and helped send retail pork prices to record highs. The highly contagious Porcine Epidemic Diarrhea virus is puzzling scientists searching for its origins and its cure and leaving farmers devastated in ways that go beyond financial losses.

Since June 2013 as many as 7 million pigs have died in the United States due to the virus, said Steve Meyer, president of Iowa-based Paragon Economics and consultant to the National Pork Board said. United States Department of Agriculture data showed the nation's hog herd at about 63 million as of March 1, 2014.
PEDv was first diagnosed in Ohio last May and has spread within a year to 30 states with no reliable cure in sight. U.S. packing plants may produce almost 2 percent less pork in 2014, according to Ken Mathews, USDA agricultural economist.

"Something like a tablespoon of PEDv infected manure is roughly enough to infect the entire U.S. hog herd," said Rodney "Butch" Baker, swine biosecurity specialist at Iowa State University.
The National Pork Board has spent about $1.7 million researching the virus, which is nearly always fatal in pigs younger than 21 days. With pork prices at an all-time high of $3.83 a pound, the loss of baby pigs cuts into profits for hog farmers.

PEDv does not pose a risk to human health and is not a food safety issue, the USDA says.
Months of forensic research so far have turned up no clear evidence of how the disease entered the United States.
The virus is nearly identical to one that infected pigs in China's Anhui province, according to a report published in the American Society of Microbiology journal mBio. Researchers also are exploring whether the widespread use of pig-blood byproducts in hog feed might have introduced the disease.
There have been outbreaks in recent years in Europe, Japan, Mexico and parts of South America, though in milder forms than seen in the U.S. and China.
The disease has taken root in Canada, too, where the pork industry is deeply integrated with U.S. pork production.

The virus "acts like a lawn mower" on the villi in a pig's intestines, which are the tiny projections that aid digestion, said Tony Forshey, chief of animal health at the Ohio Department of Agriculture. With their villi gone, the piglets cannot absorb nutrients from food or water, contract diarrhea and die from dehydration.
So far, no vaccine has been able to completely protect pigs from the disease. An Iowa company, Harrisvaccines Inc., has made some progress, while pharmaceutical giants Merck Animal Health and Zoetis Inc have joined with universities to begin vaccine development.

Bright yellow signs marked "PED" are popping up outside North Carolina farms warning the virus is present. One-third of North Carolina's 3,000 hog farms have been struck by PEDv since the first diagnosed case there in June 2013, the state says.
So many piglets have died that Tom Butler, a farmer who fattens hogs for market in southeastern Harnett County, is having difficulty finding animals. His herd is down 25 percent to 6,000 pigs, costing him more than $100,000.
