OBJECTIVE To evaluate the Brucella suis exposure status of pigs raised with outdoor access on farms in New York State and assess biosecurity and management practices of those farms. ANIMALS 250 pigs that were raised for commercial purposes, had access to the outdoors, and were > 4 months of age on 24 farms in New York State. PROCEDURES Farms were randomly selected from a sampling frame generated for the study and contacted to recruit them to participate. Participating farms were provided a questionnaire to complete. Up to 30 pigs per farm were tested for serum anti-Brucella antibodies. RESULTS Farm were classified as seasonal and year round. Seasonal farms raised pigs for slaughter, and year-round farms bred pigs, raised them for slaughter, and sold live pigs to others to raise. None of the 250 pigs had antibodies to Brucella spp. Nevertheless, the biosecurity assessment revealed a need for enhanced practices in procurement and management of swine in a wide range of areas. CLINICAL RELEVANCE There was no evidence for ongoing B suis infection on these swine farms in New York State, but biosecurity and preventive practices at these facilities could be improved to prevent the introduction and spread of B suis and other pathogens.
