Economic feasibility analysis for an automated on-line poultry inspection technology

On-line carcass inspection of chickens in the United States is currently done using visual (organoleptic) methods. Inspectors from the USDA Food Safety and Inspection Service (FSIS) inspect the viscera and carcass and, for older birds, the heads using a sequence of observations and palpations at a postmortem inspection station. The streamlined inspection system (SIS) and the new line speed inspection system (NELS) are the most prevalent visual inspection methods. The former has a line speed of 70 birds/min with two inspectors per line, and the latter has a line speed of 91 birds/min requiring three inspectors per line. Both inspection methods are labor intensive and prone to human error. In addition, the speed of the slaughter line is dictated by the number of birds per minute that can be inspected by FSIS inspectors. Ninety-one birds/min is currently the maximum visual inspection line speed allowed under current Federal regulations. This study evaluates the economic benefits of using automated inspection in place of visual inspection from the perspective of both the slaughter plant and FSIS. The results indicate that FSIS and slaughter plants would gain economic benefits by using automated inspection in place of visual inspection. The economic benefits to FSIS would accrue from labor savings, whereas the economic benefits to slaughter plants would accrue primarily from increased throughput from faster inspection line speeds.
