Sanitation performance across the commercial cruise industry is documented by the United States Centers for Disease Control and Prevention (CDC) Vessel Sanitation Program (VSP). Under federal public health regulations, all passenger vessels calling at United States ports carrying 13 or more passengers undergo unannounced, comprehensive sanitation inspections twice per operational year.
This review examines all recorded inspection scores over the five-year period leading to 2026-09-17 (Thursday, September 17, 2026), aggregated by parent operating corporation.
Five-Year Inspection Summary
| Parent Corporation | Fleet Vessels Tracked | Five-Year Inspections | Median Score | Scores Below Threshold (85 or Lower) |
|---|---|---|---|---|
| Carnival Corporation & plc | 5 | 7 | 97.0 | 0 |
| Royal Caribbean Group | 4 | 5 | 98.0 | 0 |
| Norwegian Cruise Line Holdings Ltd. | 2 | 2 | 96.0 | 0 |
| Disney Experiences | 2 | 2 | 99.0 | 0 |
| MSC Group | 1 | 1 | 95.0 | 0 |
| Virgin Voyages | 1 | 1 | 97.0 | 0 |
| Viking Holdings Ltd | 1 | 1 | 97.0 | 0 |
Methodology and Aggregation Rules
All calculations are derived from public inspection reports published by CDC VSP. The standard passing threshold requires a score of 86 points or higher out of 100 possible points. Inspections resulting in 85 points or lower represent non-satisfactory sanitation findings under the operations manual in force on the inspection date.
Line-at-the-time assignments reflect the operating company on the precise date of inspection. When ships transfer ownership or operating brands between corporate divisions (such as the transfer of Costa Luminosa to Carnival Cruise Line as Carnival Luminosa), inspection records remain bound to the historical operator in force on that date.
Key Observations
- Across 18 recorded inspections spanning the five-year evaluation window, the overall industry median score was 97.0 points.
- Zero inspections fell below the passing threshold of 86 points during this five-year period among the tracked sample fleet.
- Disney Experiences maintained the highest median score at 99.0 points across its tracked inspections, followed by Royal Caribbean Group at 98.0 points and Carnival Corporation & plc at 97.0 points.
All data figures are synchronized with official CDC VSP releases as of 2026-09-17 (Thursday, September 17, 2026).
