poultry insensible-electric or gas<br />

and other airborne particles. This is all<br />

eliminated with a correctly functioning<br />

CAS system.<br />

There are disadvantages, not the least is<br />

that gas stunning has high installation<br />

and operating costs. Another disadvantage<br />

is that insensibility is not instantaneous.<br />

According to Dr. Temple Grandin, of<br />

Colorado State University and renowned<br />

animal welfare expert, “when gas stunning<br />

systems are compared to electrical<br />

stunning, the tradeoff between stressful<br />

reactions to the gas and a reduction<br />

in handling stress by eliminating live<br />

shackling must be considered. Electrical<br />

stunning provides instant insensibility,<br />

but live shackling is definitely bad for<br />

bird welfare.” She adds that “…direct<br />

observation is the only way to verify that<br />

a commercial CAS system is inducing<br />

insensibility with a minimum of<br />

discomfort.”<br />

From a further processing standpoint,<br />

many of the largest U.S. cooking<br />

operations request or require that their<br />

turkey or chicken meat come from gasstunned<br />

poultry. They have found through<br />

studies that meat tenderness improves<br />

with gas stunning and that blood spots in<br />

the meat vanish. This, they say, makes for<br />

a tastier product with more eye appeal.<br />

Still, research continues. Variations in<br />

the gas mixtures used, as well as the<br />

way they are delivered, are constantly<br />

changing. One similar stunning method<br />

is called the Low Pressure Atmospheric<br />

System. In a news release Arkansasbased<br />

chicken processor O.K. Foods,<br />

<strong>Inc</strong>. announced that it has been working<br />

with TechnoCatch LLC and Yvonne<br />

Vizzier Thaxton, Ph.D., Mississippi<br />

State University, to create a new and<br />

more humane way to process poultry.<br />

This procedure differs from other CAS<br />

methods in that it does not use gases. The<br />

company states that “the LAPS system<br />

works by reducing the oxygen level in<br />

poultry live haul cages. This reduction<br />

of oxygen causes hypoxia and a sense of<br />

euphoria similar to climbing to altitude<br />

in an airplane. LAPS is a superior<br />

alternative to conventional electrical<br />

stunning because birds are insensible<br />

before unloading, shackling and stunning,<br />

reducing bird stress levels and eliminating<br />

animal welfare concerns as birds are<br />

introduced to the plant.”<br />

Whether out of concern for animal welfare,<br />

worker safety or meat quality, CAS is<br />

increasingly mainstream. Poultry processors<br />

need to weigh the advantages of gas<br />

stunning against economic considerations<br />

when deciding between traditional electric<br />

water bath stunning and this ever more<br />

popular method of rendering turkeys and<br />

chickens insensible prior to slaughter.UB<br />
