Excerpts from the report: The purpose of Federal inspection of poultry in processing plants is to assure a wholesome product. It is to the advantage of all people concerned—the producer, the processor, the inspector, and the consumer—that Federal poultry inspection be carried out efficiently and effectively. The study reported here was made to determine (1) the time required to perform Federal inspection; (2) the influence of line speed and carcass position, spacing, and conditions on inspection rates; (3) the influence of types of equipment and their condition on inspection efficiency; (4) the validity of eviscerating rates reported in earlier research, where these were applicable; and (5) the optimum crew (inspection and eviscerating) size and makeup at specified line speeds and types of equipment. The broad objective of this research was to determine the conditions under which evisceration and inspection of chickens can be coordinated most efficiently in a commercial processing plant.
