Progress and challenges in animal handling and slaughter in the U.S. (2006)

Abstract

Most plants were able to greatly improve welfare by improving stunner maintenance; installing non-slip floor gratings in stun boxes and better training. They also had to make simple, low cost changes to eliminate distractions that cause animals to balk and refuse to move. The most common ways to improve animal movement were: (1) install a lamp on a dark race entrance, (2) move ceiling lamps to eliminate sparkling reflections, (3) muffle air hissing, (4) install shields and solid sides on races to prevent animals from seeing moving people up ahead and (5) eliminate air drafts that blow in the faces of approaching animals. A major remaining problem area is in plants that are not in a program of yearly audits by restaurants. Serious animal abuse has occurred in some of these non-audited plants.
