How Seattle grades restaurants

Inspectors add points for each violation, so a lower score is better. 0 means no violations.
Red violations are high-risk practices that can directly cause foodborne illness. Blue violations are lower-risk maintenance and sanitation issues.
Routine inspections with 35 or more red points, or 90 or more total points, are unsatisfactory and require a return inspection.

Severity levels

Critical Can directly make someone sick: food temperatures, contamination, pests, hand-washing.
General Cleanliness, maintenance and facility problems.
Paperwork Missing signs, permits or paperwork.
