Any suspect feed materials should be tested. Toxic or poisonous reactions affect both humans and animals. Unless adequate ventilation is provided, conditions potentially fatal to humans and animals can develop very quickly. Properly designed buildings with adequate ventilation will prevent the accumulation of toxic gases under normal operating conditions. Additional precautions may be necessary whenever contents of manure pits are being agitated or when manure pits are entered for maintenance.
Dusts are common in livestock operations and present a hazard to animals and humans.
Use and store only dry grain and dry, well-cured forage. Animal areas should be kept as clean and dust-free as possible. Provide adequate ventilation whenever movement of animals is not possible or practical. Michigan State University, Agricultural Engineering Department.
