Title Exposure to air contaminants in chicken catching
Bibliographic information Aug. 1995, Vol.56, No.8, p.804-808. Illus. 12 ref.
Abstract The job of a chicken catcher in the modern poultry industry is to catch the chickens (raised in chicken houses housing up to 50,000 birds) by hand and place them in cages for transportation by truck to a processing plant. Two methods are used for loading birds into cages: the drawer method (DM) (loading birds into cages mounted in a rack standing on the floor) and the truck method (TM) (loading birds into cages on a trailer truck parked inside the chicken house). According to this Danish study, DM catchers are exposed to higher concentrations of hazardous substances (endotoxins, viable bacteria, viable fungi) than TM catchers, except for ammonia. Full-shift dust exposure exceeded the Danish occupational exposure limit of 3mg/m3 by at least a factor of 2 (the concentration of respirable dust ranged from 18% to 28% of the total dust concentration). Bacterial endotoxin concentrations in total dust were also 4-8 times higher than the 10ng/m3 limit recommended for poultry processing workers in the US. Exposure to microorganisms was also very high. In light of the high levels of exposure to airborne contaminants, the development of preventive measures is recommended.
