Using a drone, North Carolina filmmaker Mark Devries has filmed what he says are cesspools of pig waste at farms in the state that supply hogs to Smithfield Foods Inc. His footage can be seen at factoryfarmdrones.com.
Some of the pools of waste, he says in the video, are the size of four football fields. Devries also said some of the waste is sprayed in the air, contaminating adjacent neighborhoods.
