Hog feces particles are likely getting inside North Carolina homes that are close to a large hog operation, a university study shows. The report, presented as evidence in a federal lawsuit, may contradict claims that hog operations don't transmit pathogens to nearby properties. The bacteria, called pig2bac, are a marker for pig feces, which contains hundreds of other pathogens many of which can make people sick.The evidence was filed in federal court last Friday and comes as state Republicans are pushing forward a bill to shield large-scale farms from many of the legal claims that seek to recover damages from lost property value, health effects and overall suffering from living near hog farm pollution and smells. The evidence was from a study by Shane Rogers, a professor and researcher at Clarkston University in New York, who tested the air and land and exterior walls of 17 homes near a Smithfield Foods hog confinement operation. The testing was done was done in 2016.
