The primary findings:
- "On average, inspectors cited fewer violations at each successive establishment inspected throughout the day, the researchers found. In other words, inspectors tended to find and report the most violations at the first place they inspected and the fewest violations at the last place."
- "They also found that when conducting an inspection risked making the inspector work later than usual, the inspection was conducted more quickly and fewer violations were cited."
- "The level of inspector scrutiny also depended on whatever had been found at the prior inspection that day. In short, finding more violations than usual at one place seemed to induce the inspectors to exhibit more scrutiny at the subsequent place.On the other hand, finding fewer violations than usual at one site had no apparent effect on what the inspector uncovered at the subsequent establishment."
They concluded: "The researchers estimate that tens of thousands of Americans could avoid food poisoning each year simply by reducing the number of establishments an inspector visits on a single day. Often, inspectors will cluster their schedule to conduct inspections on two or three days each week, saving the other days for administrative duties in the office. While this may save travel time and costs, it might be preventing inspectors from doing their jobs more effectively."
Nothing we probably wouldn't have guessed ourselves. I bet the inspectors would love to do less audits then they currently have to do. And while this applies to food service inspection, there are things food processing facilities have used to their advantage over the years in dealing with inspectors or auditors - pushing the plant walk-through until later in the day....taking the auditor into the best parts of the facility first.
