Livestock housing facilities which are confined or semi-confined units where animals are reared on slotted floors over manure pits or on an accumulation of manure may present health hazards to workers. The concentration of animals and manure results in potentially excessive direct human contact with pathogenic microorganisms and the release of harmful gases from the slurry within the confinement unit. Ammonia (7664417), carbon-dioxide (124389), hydrogen-sulfide (7783064), and methane (74828) are found in the air in animal confinement units at high levels, and chronic and acute poisonings have occurred in lifestock. Leptospires and salmonella may be transmitted by airborne methods, and infected animals may shed the pathogens for weeks or months. Leptospires may survive for 138 days at summer temperatures in aerated beef cattle manure slurry and salmonella for 47 days at winter temperatures. (Contract No. 099-74-0098)
