Overview of Sanitation Rankings
A recent study conducted by Squaremouth Travel Insurance has identified the cleanest cruise lines based on data from the Centers for Disease Control and Prevention's (CDC) annual health and hygiene inspections. The study highlights that independent cruise brands tend to achieve higher sanitation scores compared to larger conglomerates, and notably, the age of a ship does not significantly impact its cleanliness rating.
Cruise ships are evaluated on a 100-point scale, with a passing score set at 86 or above. The top three cleanest cruise lines, each scoring 99 out of 100, are Viking Ocean Cruises II Ltd., Viking Expedition Operations, and Crystal Cruises. Other notable mentions in the top ten include Oceania Cruises, P&O Cruises, Japan Grace, Virgin Voyages, Norwegian Cruise Line, Celebrity Cruises, and Royal Caribbean International, all of which scored above 97.
Importance of Sanitation Protocols
The CDC's Vessel Sanitation Program (VSP), established in 1975, plays a crucial role in maintaining health standards on cruise ships. Gavin Macgregor-Skinner, an infection prevention expert, emphasized the importance of this program for the safety of passengers and crew. Ships participating in the VSP undergo two unannounced inspections annually, focusing on various aspects such as medical facilities, potable water systems, and dining areas.
Brian Sansoni, senior vice president of communications at the American Cleaning Institute, noted that cruise ships are shared environments where numerous individuals frequently touch the same surfaces, increasing the potential for germ transmission. He stated, "Without strong cleaning and hygiene practices, germs can spread quickly, increasing the risk of illness among passengers and crew."
Discrepancies in Health Data
Despite the high sanitation scores, the study revealed an unexpected finding: there is no direct correlation between cleanliness and the occurrence of viral outbreaks, such as norovirus, which are common on cruise ships. In 2025, the CDC reported 23 onboard outbreaks, yet the data indicated that viral illnesses can spread even on the cleanest vessels. Macgregor-Skinner clarified that cruise lines are unique in their obligation to report illnesses to the federal government, which may lead to a perception of higher incidence rates compared to other sectors like restaurants and hotels.
Criticism of Cleaning Protocols
While the study underscores the effectiveness of sanitation protocols, critics argue that inadequate cleaning can still pose risks. Sansoni warned that when cleaning practices falter, germs can linger on high-touch surfaces, leading to rapid spread in close quarters. This highlights the ongoing need for vigilance in maintaining hygiene standards across the cruise industry.
Conclusion
The findings from the CDC's sanitation inspections reveal that while certain cruise lines excel in cleanliness, the risk of viral outbreaks remains a concern. The cruise industry, as a whole, is deemed cleaner than other travel sectors, but continuous adherence to strict cleaning protocols is essential to safeguard the health of passengers and crew.
