Monitoring stunning effectiveness in poultry slaughter facilities ensures that birds are unconscious before killing, reducing the welfare impact of slaughter.
Inadequately stunned poultry that regain consciousness before the killing cut experience the terror of the slaughter process while conscious - an extreme welfare failure at industrial scale. The failure rate of water bath electrical stunning varies between facilities and is influenced by equipment maintenance, bird handling, and worker training. Industrial processing speeds make individual assessment of stunning efficacy impractical without automated systems. Investment in monitoring technology - EEG assessment, automated behavioral monitoring, and regular equipment calibration - reduces the rate of failed stunning and prevents the most severe welfare violations. Regulatory requirements for monitoring would drive adoption across the industry.
