Gov. Pat McCrory, R-NC, says thousands of animals drowned from the aftermath of Hurricane Matthew. Most were chickens on poultry farms.
McCrory is deciding on rules to dispose of the carcasses.
On the other hand, hog slaughter fell starting the week after the closure of three facilities in the southeast due to flooding.
Officials are watching to see if flood waters breach some livestock lagoons in the region, warning about the potential health impacts of the water.
