Odor control on a swine confinement facility can be a major concern to the farmer. Problems with odor can arise in the form of neighbor complaints and can occasional lead to legal proceedings. Using odor preventive strategies, the community and the hog facility can happily coexist. An odor is a subjective measure, what determines a bad odor is highly dependent on individuals’ attitude, and past experience. Facilities, which appear clean and aesthetic from the exterior, are much less susceptible to complaints. Complaints of water pollution, flies, and noise, can be avoided by choosing an adequate location during the design phase of the facility. Generally speaking, gases and other compounds produced in swine farming seldom exceed safe air standards that are hazardous to humans. Only under certain situations (manure agitation) do dangerous gas concentrations prevail. Thus, odors are seen as nuisance pollutants. Utilizing the appropriate preventive measures most of these nuisances can be avoided.
