Every cruise line will tell you their ships are the cleanest, most sanitized floating cities on the planet. But when the CDC shows up unannounced with a clipboard and a black light? The scores tell a very different story.
We took every CDC Vessel Sanitation Program inspection score in our cruise ship database and ranked them. All of them. No exceptions, no sponsored placements, no “well, they had a rough quarter.”
Here’s how to read the rankings and what they actually mean for your next booking.
The Six Rankings We Track
Head to the Ship Rankings page and you’ll find six different ways to slice the data:
Cleanest Cruise Ships
Ships sorted by their most recent CDC inspection score, highest first. These are the ships that ace the surprise inspections — scoring 96 or above consistently. If you’re the type who packs Clorox wipes “just in case,” these ships will let you relax a little.
Dirtiest Cruise Ships
The flip side. Ships sorted lowest score first. Before you panic — most cruise ships score in the 90s. But a few consistently underperform, and you deserve to know which ones before you hand over your vacation budget.
Most Outbreak-Prone Ships
Ranked by total CDC-reported gastrointestinal illness outbreaks. Some ships just can’t catch a break (or, more accurately, can’t seem to stop the norovirus from catching their passengers). This ranking shows which ships have the most outbreak incidents on record.

Most Improved Ships
Ships whose scores are trending upward. These are the comeback stories — ships that may have had a rough patch but are cleaning up their act (literally). If a ship bombed an inspection two years ago but just scored a 98, that matters.
Biggest Decline
The opposite of most improved. Ships whose scores are sliding. A ship that scored 100 last year and 89 this year might have a story worth reading before you book.
Perfect Score Ships
The elite club. Ships that have scored a flawless 100 out of 100 on a CDC inspection. This is genuinely hard to do — the inspections cover everything from galley temperatures to pool chemical levels to crew hygiene practices. A perfect score means zero violations found.
How to Read the Rankings
Each ranking shows a sortable table with the ship name, cruise line, latest score, average score, total outbreaks, and trend direction. The scores are color-coded:
- Green (96-100) — Excellent. This ship is clean.
- Yellow (86-95) — Passing, but there’s room for improvement.
- Red (below 86) — Failed the CDC inspection. Proceed with caution.

Why Rankings Matter
Look — most cruise ships are reasonably clean. The industry average hovers in the mid-90s. But when you’re choosing between two ships for a $3,000 vacation, wouldn’t you rather pick the one with a 98 over the one with an 87? Especially when the 87 has had three norovirus outbreaks in two years?
The rankings give you that context at a glance. No Googling, no CDC PDF hunting, no trusting cruise line PR departments.
