[Animal welfare and workers' protection during electric stunning of poultry for slaughter].

Every slaughter process involves problems as to animal welfare as well as safety aspects and the protection of workers. With poultry these are basically concentrated on electrical stunning. Electrical currents and voltages suitable for stunning slaughter animals are principally also hazardous for man in what respect body resistance is of crucial importance. Potential hazards have to be looked upon as present in spite of existing safety regulations. Comparatively high stunning voltages for poultry recently proposed because of animal welfare considerations have met objections not only from the viewpoint of meat hygienic but workers' safety regulations as well. While the former meanwhile could be overcome the latter still has to be investigated, especially as a regulation on the electrical stunning of poultry is currently being prepared. In this respect the question whether adequate stunning efficiency can be obtained by reducing the voltage and prolonging the time of exposure is of special interest. First preliminary results of such investigations are presented. To ensure workers' safety other related aspects should also be taken into account and examined for improvements.
