(Reuters) – Confirmed cases of Porcine Epidemic Diarrhea Virus increased by 296 in the week ended March 15, bringing the total number to 4,757, according to data released on Thursday by the U.S. Department of Agriculture’s National Animal Health Laboratory Network (NAHLN).
The U.S. and Canadian hog industries have recently developed partnerships to research what role, if any, feed or feed ingredients have had in the transmission of PEDv, the National Pork Board said earlier this week. The report from USDA’s NAHLN does not include test results from feed samples.
No new states reported cases leaving the affected states at 27, the group of animal researchers said.
While one case can represent an individual animal or an entire herd at a single site, hog industry analysts estimate PEDv has killed an estimated 5 million U.S. hogs since it was discovered in May 2013.
