Swine virus surging

The deadly porcine epidemic diarrhea virus (PEDV) is on the rise in U.S. swine herds in December, as producers anticipated and dreaded as cold weather sets in.

Testing data from the USDA National Animal Health Laboratory Network shows 140 new cases reported for the week of December 1, 2013. This represents the highest number of new cases reported in a single week since the introduction of the virus in April. The addition of Nebraska brings to 20 the number of states reporting at least one confirmed case of PEDV virus in a swine herd.
