LAPS is a patented method to achieve an irreversible stun in poultry. Low atmospheric pressure is attained by using computer controlled slow decompression, which allows the body of the bird to adjust to changes in pressure and thus lose consciousness. LAPS sets a new paradigm for controlled atmospheric stunning without gaseous addition or electrical shock. The benefits of LAPS are not only humane, but also improve the economics of stunning and meat quality. LAPS has received a No-Objection letter from the USDA and CFIA and has the Seal of Approval for Humane Equipment by the American Humane Association.
