Campylobacter is the leading cause of bacterial gastroenteritis in the United States. The objective of this study was to investigate the prevalence of Campylobacter in newly constructed broiler houses and compare three microaerophilic gas delivery methods used to culture Campylobacter in the laboratory. Of 2,300 litter, 900 fecal, and 45 water samples, only 5, 6 and 1 of the samples, respectively, were confirmed positive. style='mso-spacerun:yes'> Results indicated litter moisture content was different across day, location and house. An interaction was detected for litter pH between day, location and flock. Temperatures averaged 26.8°C inside and 27.6°C outside. style='mso-spacerun:yes'> No difference in colony counts were detected among the gas delivery methods. In conclusion, the newly constructed houses showed no significant prevalence of Campylobacter. style='mso-spacerun:yes'> High litter pH, low temperatures, and other onarm management strategies may have suppressed Campylobacter’s ability to colonize the litter. When selecting a gas delivery method price and space should be considered.
