CURRENT LAWSUITS MOVE FORWARD IN HOG FARM NUISANCE CLAIMS: Last October, over the objections of Murphy-Brown, the court allowed investigators to visit the hog farms, take air-quality samples, record video evidence, send in drones and catch as many pathogen transmission vectors – flies – as they could. The lawsuits also allege that the smells, pig transport trucks, open-air lagoons and spraying of waste onto fields are so offensive that people living in the vicinity can’t have visitors to their homes or have outdoor activities. The company says it complies with all existing laws and regulations, rendering the lawsuits groundless. The federal trials cleared their most recent hurdle Thursday. The state legislature passed proposed legislation protecting hog farms against lawsuits, after lawmakers agreed to remove a provision that would have made the protections retroactive to the Murphy-Brown lawsuits.
