SPRINGFIELD, Ill. (AP) -- Illinois agriculture officials say there have been hundreds of cases of a deadly pig virus in Illinois.
The (Springfield) State Journal-Register reports there were 360 cases of porcine epidemic diarrhea in Illinois through March.
But hog farmers weren't required to start reporting the illness until last week.
PED has killed millions of pigs in 27 states since showing up in the U.S. last May. Illinois is among the hardest-hit.
The disease has been blamed for recent increases in bacon and pork prices and farmers have struggled to control the virus, because little is known about how it spreads. Piglets are most at risk.
The virus doesn't affect humans.
The Illinois Pork Producers Association says the virus has spread throughout the state and is impacting large and small farms.
