Do Newer Cruise Ships Pass CDC Inspections Better?
Do newer cruise ships score higher on CDC inspections? We matched 182 ships to the year they entered service. Slightly, but age explains only about 6%.

Written from the Spotless Sailor traveler archetype, one of the 14 we use. I read the inspection report before the brochure. Every number below is the CDC's or ours, with its date.
People ask me some version of this every week: is a new ship cleaner? It's a fair guess. New galleys, new plumbing, new everything. So I checked whether newer cruise ships actually score better on CDC inspections, using the scores rather than the guess.
How I checked
The CDC's Vessel Sanitation Program inspects cruise ships unannounced, scores them out of 100, and calls 86 and above passing. Its Green Sheet lists the latest score for every ship it inspects. On October 8, 2026, we track 206 of them, with an average of 96.5 and two below the passing line.
I matched each ship to the year it entered service, using Wikipedia's list of cruise ships, and each ship's own Wikipedia article for newer ships the list doesn't include yet. That worked for 182 of the 206. The 24 I left out are small expedition and sailing ships and a handful of new ships where I couldn't confirm the year from a source.
One limit to say up front: this uses each ship's single most recent score. A ship that scored 89 in February might score 98 in August. One inspection is a snapshot of one day.
Newer cruise ships do score higher, by a little
| Entered service | Ships | Average score | Scored a perfect 100 | Below 90 |
|---|---|---|---|---|
| 2020 or later | 45 | 98.0 | 40% | 1 |
| 2010 to 2019 | 47 | 97.0 | 30% | 2 |
| 2000 to 2009 | 64 | 96.0 | 6% | 3 |
| Before 2000 | 26 | 96.0 | 19% | 2 |
The direction is clear. The newest ships average about two points higher than the 2000s ships, and four in ten of them scored a perfect 100.
The size is the part people skip. Measured across all 182 ships, the correlation between year in service and score is 0.24. In plain terms, a ship's age explains about 6% of why one ship scores higher than another. The other 94% is something else: the crew, the line's procedures, what the inspector found that particular day.
Something I didn't expect: ships from the 2000s have the lowest share of perfect scores, lower than the pre-2000 ships. Some of that is small numbers. Some of it may be that many of the oldest ships still sailing have been heavily rebuilt; Carnival Sunrise, which entered service in 1999, scored 100 after its rebuild.
Old ships that scored 100
These all scored a perfect 100 on their latest inspection:
- Grandeur of the Seas, entered service 1996
- Enchantment of the Seas, 1997
- Disney Magic, 1998
- Explorer of the Seas, 2000
- Carnival Legend, 2002
- Mariner of the Seas, 2003
New ships that didn't
And these entered service in 2021 or later and scored below 95:
- Sun Princess, 2024: 89 (February 15, 2026)
- Enchanted Princess, 2021: 93
- Viking Mars, 2022: 93
- MSC Seashore, 2021: 94
- Silver Dawn, 2021: 94
- Ilma, 2024: 94
Sun Princess is the one worth noting. It's Princess's newest ship and its 89 is a pass, but it's lower than Grandeur of the Seas, a ship nearly thirty years older.
The line tells you more than the year
If age explains little, what explains more? I grouped the lines with at least five ships inspected:
| Line | Ships | Average score | Lowest | Median year entered service |
|---|---|---|---|---|
| Disney | 7 | 99.6 | 98 | 2012 |
| Oceania | 7 | 98.4 | 97 | 2000 |
| Celebrity | 12 | 97.8 | 92 | 2011 |
| Royal Caribbean | 28 | 97.4 | 89 | 2006 |
| Carnival | 26 | 97.0 | 86 | 2006 |
| Viking | 7 | 96.9 | 93 | 2021 |
| Holland America | 10 | 96.6 | 91 | 2005 |
| MSC | 8 | 96.2 | 89 | 2018 |
| Norwegian | 18 | 96.2 | 84 | 2013 |
| Silversea | 7 | 96.0 | 91 | 2020 |
| Princess | 15 | 95.9 | 89 | 2008 |
Oceania is the clearest case. Its fleet is the oldest on this list, and it averages 98.4 with no ship below 97. Viking, MSC and Silversea run much younger fleets and average lower. Small groups, single inspections, so I wouldn't rank lines on a point or two. But it's enough to say that the year a ship was built is a weak way to guess what an inspector will find.
What I'd actually do
Don't pick a ship for being new and assume it's the cleaner choice. Look up its score, then read the report. The CDC publishes every inspection itemized by deck and room, and the reasons behind a 94 are often more useful than the number. We list the latest score for every ship on our ship health page, and I walk through one ship's full report at a time, starting with Celebrity Edge.
A new ship is more likely to score 100. An old ship can, and a new one can miss.

Frequently asked
Do newer cruise ships score better on CDC inspections?
Slightly. Ships that entered service in 2020 or later average 98.0 on their latest CDC Vessel Sanitation Program inspection; ships from 2000 to 2009 average 96.0. But ship age accounts for only about 6% of the variation in scores across the 182 ships we matched.
What is a passing CDC cruise ship inspection score?
86 or above. In the CDC's words, inspection scores of 85 or lower are not satisfactory.
Can an old cruise ship score 100?
Yes. Grandeur of the Seas (1996), Enchantment of the Seas (1997), Disney Magic (1998) and Mariner of the Seas (2003) all scored 100 on their most recent inspections.
Which cruise line scores highest on CDC inspections?
Among lines with at least five ships inspected, Disney Cruise Line averages 99.6 across seven ships on the latest scores. Oceania averages 98.4 across seven, with a fleet whose median year in service is 2000.
