If you eat pork, get ready to pay a lot more for it. A highly contagious pig virus known as “Porcine Epidemic Diarrhea virus” has now spread to 27 different U.S. states, and it has killed more than 4 million hogs since last May. Smithfield Foods, the largest pork producer in the entire world, estimates that approximately 10 percent of all adult female hogs in America have contracted the disease already, and there is a very good chance that any offspring that they have will die. That is because the mortality rate for this disease for piglets is between 80 and 100 percent.
