With the transition to increasingly larger pig production facilities, nearby residents have voiced concerns about environmental contamination, odour, and adverse health effects. The goal of this study was to evaluate outdoor airborne concentrations of ammonia, dust, and endotoxin in the environment near 4 types of pig production facilities and one control farm with no livestock. Dust and endotoxins were detected at a distance of 60 m outside of facilities, but generally concentrations were below limits of accurate detection. The mean (and standard deviation) for outdoor ammonia concentrations were: 0.251 (0.064) ppm-large confinement; 0.086 (0.091) ppm-medium confinement; 0.214 (0.160) ppm-small confinement; 0.139 (0.188) ppm-small conventional;
