If antemortem and postmortem inspections are the "entry exams" for the meat, processing inspection is the continuous monitoring of a student throughout the school year. Passing the entrance exam (the carcass inspection) is just the beginning; the meat must continue to meet strict standards for hygiene and "behavior" (safety and labeling) until the moment it "graduates" (leaves the facility for the consumer). Any "failing grade" at any step results in immediate detention (retention) of the product.
