Method for stunning and killing humanely poultry using low atmospheric pressure controlled

摘要

Method for stunning and killing humanely poultry, the method comprising: enclosing the poultry in a sealed chamber; subjecting decompression chamber at a continuous rate to a decompression pressure of from about 71 kPa gauge to about 91 kPa gauge as measured at mean sea level over a lapse of time from about 30 seconds to about 120 seconds; and maintaining the decompression pressure for from about 15 seconds to about 60 seconds, so that the poultry achieve a state of death, wherein about 90% or more of the activity of the brain waves of poultry ceases before the poultry undergo complete cardiac fibrillation.
