A recent study by Squaremouth Travel Insurance analyzing CDC health and hygiene inspection data has revealed the top 10 cleanest cruise lines, challenging the perception that the cruise industry is a breeding ground for germs. The findings show that age doesn't necessarily impact a cruise line's ability to achieve high cleanliness scores, with a mix of older and newer ships ranking among the best. The study highlights the industry's focus on sanitation and transparency, providing a more positive outlook on cruise ship cleanliness.

Why it matters

The cruise industry has long faced criticism for its lack of transparency and accountability when it comes to health and safety. This study offers a more nuanced perspective, suggesting that the industry is taking steps to address these concerns and improve sanitation standards. The findings could help alleviate passenger concerns and reshape the public's perception of cruise ship cleanliness.

The details

The Squaremouth study analyzed data from the CDC's annual health and hygiene inspections, which require cruise ships to score 86 or above on a 100-point scale. The top 10 cleanest cruise lines include a mix of independent brands and larger conglomerates, such as Viking Ocean Cruises, Crystal Cruises, and Royal Caribbean International. Interestingly, the age of the ships did not appear to be a significant factor, with both older and newer vessels achieving high scores. This suggests that the cruise industry's focus on strict cleaning protocols and sanitation practices has been effective in maintaining high standards across the board.

  • The Squaremouth study was conducted in 2026, analyzing data from the CDC's most recent annual inspections.

What’s next

The cruise industry should continue to monitor and evaluate its progress in maintaining high sanitation standards, ensuring that all lines adhere to the same strict protocols. Ongoing transparency and accountability will be key to building passenger trust and improving the industry's reputation.

The takeaway

The Squaremouth study's findings suggest that the cruise industry is making strides in addressing concerns about cleanliness and sanitation. While the perception of cruise ships as breeding grounds for germs persists, the data shows that many lines are prioritizing strict cleaning protocols and achieving high scores on CDC inspections, regardless of the age of their vessels. This positive development could help alleviate passenger concerns and reshape the public's view of the industry.
