Every cruise ship calling at US ports gets surprise CDC health inspections scored out of 100, with 86 the pass mark. Here is how the Vessel Sanitation Program works, why Norwegian Dawn failed in 2026, and how to look up any ship's score in under a minute before you book.

Cruise ship health inspection scores are marks out of 100 awarded by the US Centers for Disease Control and Prevention (CDC) under its Vessel Sanitation Program (VSP). Inspectors board without warning, start at 100 and deduct points for violations; 86 or above is satisfactory, 85 or below is a fail. Every score and the full report behind it is public, searchable free of charge in the CDC's inspection database — so you can vet any ship in about 60 seconds before booking.
The scores are back in the headlines because Norwegian Dawn failed its unannounced inspection with an 84 on 29 March 2026 in Tampa — the only outright failure recorded so far this year. Norwegian Cruise Line has since filed a corrective action report with the CDC, and the episode is a useful reminder of what these scores do and do not tell you. A failed inspection is a snapshot, not a verdict on a ship or a brand; scores routinely swing between inspections.
How does the CDC score cruise ship inspections?
VSP inspectors work through eight broad areas: potable water systems, food safety in galleys and dining venues, swimming pools and whirlpool spas, medical facilities and gastrointestinal-illness surveillance, children's centres, housekeeping, pest management, and heating and ventilation systems. Each violation carries a weighted deduction, and violations are classed as critical or non-critical — a fault that could directly cause illness, such as an unsafe food temperature, costs far more than a worn tile or a missing sign.
That weighting is why a 95 does not mean a ship is 5 per cent dirty. A ship can lose a handful of points on paperwork and minor maintenance and still run an exemplary operation, while a small number of critical food-safety violations can sink a score fast. Plenty of ships also earn a perfect 100 in any given year — worth noticing, but the written report always tells you more than the number.
How often are cruise ships inspected?
Any vessel carrying 13 or more passengers on an international itinerary that calls at a US port is subject to unannounced inspections roughly twice a year, plus re-inspections when needed. The programme is not taxpayer-funded: cruise lines pay inspection fees based on ship size — from about $8,073 for the smallest vessels to more than $32,000 for the largest, under the fee schedule published in the Federal Register. Ships that never touch US ports fall outside the VSP; in European waters the closest equivalent is the EU SHIPSAN ACT framework, which coordinates ship hygiene inspections across member states.
What happens when a cruise ship fails an inspection?
A score of 85 or below triggers a required corrective action plan from the operator and a follow-up re-inspection, typically within weeks. Ships keep sailing in the meantime unless the CDC judges there is an imminent health risk — a rare step. In 2026, Norwegian Dawn's 84 was the year's only failure, but several ships scraped through at the minimum: Carnival Breeze, Kydon and National Geographic Sea Lion each scored exactly 86, while Sun Princess, MSC Meraviglia and Amadea each posted an 89 — low by industry standards, where scores in the mid-to-high 90s are the norm.
How do I check my ship's score before booking?
Go to the CDC's inspection search tool (search "CDC cruise inspection scores" or use the link in Sources below), type the ship's name and you will see every inspection score with dates, plus the full report listing each violation and the crew's on-the-spot response. The CDC also publishes the "Green Sheet", a running summary of the latest score for every ship in the programme. Reports read like restaurant inspections: item, location, deduction, correction. Skim for critical food and water items rather than counting violations.
| Score band | What it means | What a booker should do |
|---|---|---|
| 100 | No deductions at the last inspection | Nothing — a strong signal, though still only a snapshot |
| 96–99 | Typical for well-run ships; minor deductions | Book with confidence; no action needed |
| 86–95 | Passing, but read the report | Check whether deductions were critical (food/water) or cosmetic |
| 85 or below | Failed; corrective plan and re-inspection required | Look up the re-inspection score before sailing — most ships rebound quickly |
Inspection scores are one line in the due-diligence checklist alongside the practical questions we cover in our guides to whether you need a passport for a cruise, how tipping works on board and the 2026 round of gratuity increases.
Is norovirus really more common on cruise ships?
Cruise outbreaks are highly visible partly because reporting is mandatory: ships must log every gastrointestinal case and notify the CDC before arriving at a US port, and outbreaks affecting 3 per cent or more of people on board are published. No comparable public register exists for hotels, resorts or restaurants. That said, the recent numbers are genuinely elevated: 2025 set a record with 20 reported gastrointestinal outbreaks — the most since public data began in 1994, ahead of 18 in 2024 — with norovirus behind 15 of them. In 2026 the pace has eased, with eight outbreaks reported so far (five norovirus, two E. coli, one unknown), the largest on Ruby Princess in June, when 107 of 3,032 passengers fell ill. Note that outbreaks track contagious viruses brought aboard by guests as much as ship hygiene — a high inspection score is no immunity, and a low one does not predict an outbreak.
Frequently asked questions
How often are cruise ships inspected by the CDC?
Roughly twice a year, unannounced. Any ship carrying 13 or more passengers on an international itinerary that calls at a US port is covered by the Vessel Sanitation Program, with re-inspections after failures. Cruise lines pay size-based fees for each inspection, so the programme is industry-funded rather than taxpayer-funded.
What is a failing score on a cruise ship inspection?
Anything at 85 or below out of 100. A score of 86 or above is rated satisfactory. Failing ships must submit a corrective action plan and face a re-inspection; they normally continue sailing in the meantime. Norwegian Dawn's 84 in March 2026 was the only failure recorded that year to late August.
How do I check a cruise ship's health inspection score?
Use the CDC's free inspection search tool online: enter the ship's name to see every score, inspection date and the full violation report. The CDC's Green Sheet lists the most recent score for every ship in the programme. Reports distinguish critical violations, such as food temperatures, from minor cosmetic ones.
Is norovirus more common on cruise ships?
Outbreaks are more visible on cruises because reporting to the CDC is mandatory and published, unlike hotels or restaurants. Still, 2025 was a record year with 20 reported gastrointestinal outbreaks at sea, most caused by norovirus, and 2026 has logged eight so far. Most norovirus transmission overall happens on land.
