 Environmental health specialists were required to use a standard form called the Food Official Inspection Report to identify violations as they inspected establishments; the form required them to subtract a certain number of points for each violation found.Based on the number of points remaining, letter grades were then assigned and required to be prominently posted at all establishments selling food, and all establishments were also required to provide a copy of the underlying inspection report to any customer on request.Grades are available at the County Public Health Department's web site.
