Air quality inside livestock barns.

In modern livestock barns, proper indoor air quality is imperative to maintain the health and productivity of farm workers and animals. Some problems related to the health of farm workers have been noticed, especially since the 1970's, coinciding with the rapid changes from small traditional farms to large intensive livestock operations. The purposes of this Factsheet are to identify the contaminants present in the air inside livestock barns and to discuss the effects of adopting the present industrial indoor air quality standards from the Occupational Health and Safety Act by Ontario farmers.
