These often result from manure feed management procedures directly related odor, flies, dust water pollution. Animal enterprises in this country operate, general, without causing concern or complaints among neighbors. The agricultural community understands that is always associated with certain seasons and/or necessary operations responsible somewhat higher levels short duration. Productivity, however, be jeopardized social ties strained when acceptable exceeded believed exceeded. Odor commonly experienced assuming adequate ventilation, not considered harmful animals operational personnel. Likewise, there little no physiological danger stock personnel odors the environment surrounding confinement units. However, numerous reports illness — even mortality facilities waste units unsafe practices were permitted. New control products techniques appear regularly. It challenge and, specifically, industry, determine how, where benefits most likely accrue, if all. In truth, new proven farm operator sharing bruises along developer. Production reduce prevent production, minimize exposure odors, have been successful than technology after its production.
