This farm said it had a USDA inspector onsite daily. But people still got sick.

At Indiana-based Rose Acre's North Carolina farm, 3 million chickens produce about 2.3 million eggs every day, apparently under the watchful eye of a U.S. Department of Agriculture grader.That grader is supposed to be at the farm every day. Which raises a question: Why did it take an outbreak of salmonella, one that sickened 23 people in nine states, to alert officials to problems at the farm? A USDA spokeswoman acknowledged to IndyStar that a typical day for a grader involves checking a facility's equipment prior to that day's operation. It's at this point that any observed issues are addressed. After that, the grader will enter the grading booth to inspect eggs during the processing day."In this instance, our grader(s) did not observe issues that would have triggered a report to FDA inspectors," the spokeswoman said via email.
