The Centers for Disease Control and Prevention’s Vessel Sanitation Program (VSP) released its 2025 cruise ship health inspection results, and the numbers tell a clear story about who is doing the hard work of keeping passengers safe at sea. Out of 191 ships inspected throughout the year, just 24 earned a flawless score of 100 on the program’s 100-point sanitation scale – exactly 13 percent of all vessels inspected. Royal Caribbean led all cruise corporations with five ships reaching that top mark, followed by Disney Cruise Line and Viking, each placing three ships on the perfect-score list.
The CDC Vessel Sanitation Program – VSP for short – is the federal government’s dedicated public health oversight arm for the cruise industry. It helps the cruise industry prevent and control the spread of illnesses by inspecting ships to determine how well they are operating and maintaining public health standards in eight major areas. The program has operated since the early 1970s and applies to any passenger ship carrying 13 or more passengers on an international itinerary that calls at a U.S. port. Every score, every report, and every corrective action statement is published online for the public to read before they ever step on a gangway.
For cruise travelers, the VSP score is one of the most direct, government-backed pieces of consumer health data available. Restaurants do not have a national public scorecard. Hotels do not either. Cruise ships are the only travel sector that routinely reports illnesses to the CDC, and where you can find a central list of ships and their scores – you simply will not find a comparable listing for restaurants, hotels, or airplanes. Understanding what those scores actually measure – and what they do not – helps you make a genuinely informed choice the next time you’re comparing itineraries.
How the CDC Vessel Sanitation Program Works
The VSP operates on one foundational principle: surprise. These inspections are periodic and unannounced, and cruise ships under the program’s jurisdiction are subject to two inspections each year. There is no advance warning, no grace period, and no chance for a crew to prepare a show version of their daily operations. When inspectors board, they are seeing the ship as it actually runs.
Inspections usually take six to eight hours, depending on the number of inspectors, ship size, amount of time the ship is in port, and issues identified during the inspection. Teams can range from one to five inspectors depending on the size of the vessel. At the end, inspectors sit down with ship management to walk through what they found. The final report goes to the cruise line within two weeks, at which point the line must submit a corrective action plan for any deficiencies. All of that is then posted publicly on the CDC’s inspection query tool, where anyone can search by ship name, cruise line, or date.
The scoring system is straightforward. Ships begin with a perfect score of 100, and inspectors deduct points based on the public health significance of each violation they find. An 86 or higher is a passing grade. Score an 85 or below, and the ship fails – triggering a mandatory reinspection and a required Corrective Action Statement detailing how every violation will be fixed. In 2025, only one ship received a failing score, according to an industry analysis by the travel insurance comparison platform Squaremouth, which reviewed the full CDC dataset.
What Does the CDC Inspect on Cruise Ships?
Inspectors do not just walk the hallways checking for dust. Inspectors evaluate eight specific areas on ships. Each of these areas targets a real, documented pathway by which illness can spread through a vessel carrying thousands of people in close quarters.
The first area is potable (drinking) water. Inspectors examine areas of the potable water system to ensure that the drinking water is safe, and they take water samples to verify that chlorine and pH levels are correct. Food safety covers the ship’s galleys and dining rooms. Inspectors ensure that food is being stored, prepared, and served safely, check that dishwashers and other galley equipment are well maintained, and interview food service employees to verify they know safe food handling practices.
Swimming pools and whirlpools get their own scrutiny. For recreational water facilities, inspectors review charts and logs to verify that the facility is following VSP standards, take water samples to check halogen and pH levels, and interview staff to ensure they know the procedure for accidents involving feces or vomit. Beyond these three, inspectors also examine housekeeping protocols and outbreak prevention plans, the medical facilities to confirm staff understand reporting procedures for gastrointestinal illness, integrated pest management, general environmental areas such as public spaces and children’s activity centers, and crew health – specifically checking that sick crew members are not working around food or passengers. Medical staff are interviewed to ensure they know VSP procedures for managing people who have diarrhea or vomiting, and crew members are evaluated to make sure no one is working while ill.
A failing score does not always mean the ship is visibly dirty. Failing a VSP inspection does not necessarily mean a ship is filthy in the way that word conjures images of grimy cabins and moldy towels. Violations can involve documentation lapses, minor temperature deviations, or procedural gaps that are quickly corrected. That said, some violations carry far more weight than others. Issues with food temperature control or drinking water quality deduct more points than, say, a missing log entry.
Which Cruise Ships Scored a Perfect 100 in the 2025 CDC Vessel Sanitation Program?
Earning a perfect 100 in the CDC vessel sanitation program 2025 results was rare – only 13 percent of inspected vessels reached that mark. In 2025, only 24 of 191 ships inspected under the CDC program scored a perfect 100, or about 13% of vessels inspected, according to CDC inspection results cited in industry reporting.
The breakdown across cruise lines tells a revealing story: five ships from Royal Caribbean, four from Viking Cruise Line, three each from Norwegian Cruise Line, Oceania Cruises, and Celebrity Cruises, two from Holland America, and one each from Disney Cruise Lines, Regent Seven Seas, MSC, Seabourn, and Silversea. Among the specific ships that stood out, Royal Caribbean’s Utopia of the Seas earned a 100 in July 2025; Viking Ocean Cruises placed three ships on the list – Viking Orion, Viking Neptune, and Viking Sea; and Disney Cruise Lines placed three ships as well, with the Disney Wish, Disney Magic, and the brand-new Disney Treasure all achieving the top mark.
Among individual ships cited for top sanitation performance, Seabourn Encore, Oceania Vista, and Seven Seas Grandeur also achieved perfect 100 scores on recent inspections, with Oceania Vista reported to have maintained an unbroken streak of perfect scores since its debut in 2023. Meanwhile, Margaritaville at Sea made headlines by having both ships in its two-vessel fleet – the Paradise and the Islander – achieve perfect scores, a rare feat for a smaller, independent cruise line.
At the cruise line level, the picture was equally competitive. The top three cleanest cruise lines of 2025 were Viking Expedition Operations, Viking Ocean Cruises II Ltd, and Crystal Cruises, all scoring an average of 99 out of 100. When you look at parent corporations rather than individual brands, Viking, Virgin, and Norwegian ranked highest, with sanitation scores of 98.75, 97.67, and 97.39, respectively.
One detail in the 2025 data consistently surprised industry analysts. Perhaps the most surprising trend among the top-scoring ships is that age does not appear to be a factor in cleanliness. Royal Caribbean’s Adventure of the Seas, which debuted in 2001, sits alongside the Utopia of the Seas, which debuted in 2024, with both receiving the top score of 100, and over a quarter of the ships that earned perfect scores are at least ten years old. Sanitation is a matter of daily habits and crew culture, not a function of how new the carpets are.

Why Clean Ships Still Have Outbreaks
Here is the part most travelers find counterintuitive: a top sanitation score does not guarantee an illness-free voyage. Cruise ships are frequent settings for norovirus and other gastrointestinal illnesses – the CDC reported 23 onboard outbreaks in 2025, a 28% increase over 2024. Critically, the data shows no correlation between the number of onboard viral outbreaks and sanitation scores, proving that viral illness can easily spread on the cleanest of ships.
This is a biology problem, not a cleanliness failure. Norovirus (a highly contagious virus that causes inflammation of the stomach and intestines, known as gastroenteritis) spreads primarily through direct person-to-person contact and contaminated surfaces. The virus can survive on surfaces for days and is not killed by many alcohol-based hand sanitizers – handwashing with soap and water is the best way to reduce transmission. On a ship carrying 4,000 passengers and 1,500 crew, a single infected traveler who boards before showing symptoms can expose dozens of people within hours. The VSP inspects the ship’s systems. It cannot inspect every passenger.
This is why public health experts emphasize that sanitation scores and outbreak data measure two genuinely different things. A ship can have perfect food storage protocols and still have a passenger who got sick two days before embarkation and infected others at the first dinner seating. Cruise lines are the only part of the travel sector that routinely report illnesses to the federal government, and as one public health expert noted, it is very important not to confuse the wider availability of cruise health data with a higher incidence rate on cruise ships compared to settings like restaurants, hotels, and planes.
The Cruise Lines International Association (CLIA) reports that the chance of a cruise passenger experiencing a gastrointestinal illness is about 1 in 5,500 – compared to roughly 1 in 15 on land. That comparison needs context – the heightened reporting requirements for ships make their numbers more visible – but it does illustrate that cruise ships are not uniquely dangerous environments.
The Outlook for 2026: Staffing Cuts and What They Could Mean
The 2025 results come with a significant caveat for the year ahead. Mandatory CDC staffing cuts issued by the Trump Administration are expected to put strain on the VSP program in the coming year, which further highlights the need for travelers to consider the health risks associated with cruises and to protect themselves with cruise medical coverage.
The VSP has operated since 1975 as a joint effort between the federal government and the cruise industry. Reduced staffing means fewer inspectors available to board ships at U.S. ports, which could translate to longer gaps between inspections or a reduction in the total number of ships inspected annually. As Gavin Macgregor-Skinner, an infection prevention expert and epidemiologist, noted, the federal Vessel Sanitation Program is “critical for the health and safety of passengers, staff and the locations that cruise ships visit.” If inspection frequency drops, the competitive pressure that drives cruise lines to maintain high standards year-round could also ease.
This is precisely why travelers who care about cruise ship cleanliness ratings should check scores actively rather than assume ships are being regularly evaluated. The CDC’s VSP public database shows the date of each inspection alongside the score. If a ship you are considering has not been inspected recently, that is worth noting.
What to Know Before You Book: Using Inspection Data Wisely
Knowing how to read the VSP data turns it from a headline into a genuinely useful planning tool. A single perfect score is meaningful, but a pattern of consistently high scores across multiple inspections tells you more. A ship that scored 97, 98, and 100 across three inspections demonstrates a sustained operational culture, not a lucky day when inspectors arrived.
You can look up cruise ship sanitation scores directly on the CDC’s inspection query tool in about 60 seconds. Search by the name of your ship, review the most recent score, and click through to the full report to see exactly which areas – if any – had points deducted and why. A 92 that lost points only on paperwork issues reads very differently from a 92 that had food temperature violations in multiple galleys.
For the health-conscious traveler, combining the VSP score check with a few practical personal habits closes most of the remaining gap that inspection scores cannot cover. Norovirus is very contagious, but you can take steps to stop it from spreading – wash hands well with soap and water, since hand sanitizer alone does not work well against norovirus. Carry your own hand soap in travel size and use it before every meal, every time you return from a shore excursion, and after touching elevator buttons, railings, or buffet serving utensils. These are the contact surfaces that the VSP cannot police, and they are where passenger-to-passenger transmission most commonly occurs. You can read more about how norovirus can linger on surfaces and fabrics and what you can do to reduce your risk of exposure.
Travel insurance with medical coverage is also worth securing before a cruise, particularly for anyone over 60 or with a pre-existing health condition. People with preexisting medical conditions or special needs considering cruise travel should prepare accordingly – medical facilities on cruise ships can vary widely depending on ship size, itinerary, cruise duration, and passenger demographics.
What This Means for Your Next Voyage
The 2025 CDC vessel sanitation program results are genuinely good news for anyone planning a cruise. The industry’s overall average score landed near 96 out of 100. Only one ship failed outright. And the 24 ships that reached a perfect 100 – roughly 13 percent of all vessels inspected – did so by maintaining consistent daily standards across every area an inspector evaluates, from water quality to kitchen hygiene to crew health protocols. That takes real effort, and it matters for passenger wellbeing.
At the same time, the data is a starting point, not an endpoint. Check the CDC inspection score for your specific ship before you book, look at how recently the inspection was conducted, and read the full report rather than just the number. Pack real soap alongside your hand sanitizer. If you feel unwell in the days leading up to embarkation, contact your cruise line about your options – bringing norovirus on board puts everyone else at risk. A cruise ship with a score of 100 is an impressive achievement. Keeping it that way, voyage after voyage, is a daily commitment by thousands of crew members. Your own habits on board are the final variable in that equation.
