Inspections of establishments are based on a 100 point scale. Debit points are assigned based on the category of the violation. Not all items have the same weight. Critical items are weighted at 4 and 5 points, and less serious items are weighted at 1 and 2 points. Food service establishments scoring less than 85 are re-inspected within 10 working days. Those scoring less than 65 are subject to closure. Critical items must be corrected immediately, or within 48 hours, unless the violations are corrected at the time of the inspection being conducted.
