When planning a vacation at sea, cleanliness is one of the most important factors to consider. With thousands of passengers and crew members on board, cruise ships must maintain the highest hygiene standards to ensure the safety and comfort of everyone. In this article, we will discuss the top cleanest cruise ships and cruise lines, helping you make an informed decision before you book your next sea getaway.
Why does cleanliness matter on cruise ships?
Cruise ships are essentially floating cities. They house restaurants, pools, spas, gyms, and even hospitals. Given the closed environment, cleanliness is crucial to prevent the spread of illnesses such as norovirus or the flu. The CDC's cleanest cruise ships are consistently ranked based on how well they maintain hygiene standards through the Vessel Sanitation Program. These inspections ensure that ships follow the strictest health guidelines, making them some of the safest cruise ships to travel on.
Advanced sanitation methods, strict cleaning protocols, and trained staff keep the steps aboard the cleanest cruise ships in the world spotless, from kitchens and dining rooms to pools and children’s activity areas. For passengers, choosing the cleanest cruise line isn’t just about comfort; it’s about peace of mind, knowing they’re sailing on one of the safest cruise ships with the highest standards of hygiene and health protection.
Vessel sanitation program
Also known as stomach flu, norovirus is the most common virus to afflict cruises, as they provide an ideal setting for the highly contagious bug to spread fast, often through contaminated food, water, people and surfaces. The predominant symptoms of stomach flu are diarrhea, vomiting, nausea, and stomachache.
Under its Vessel Sanitation Program (VSP), the Centers for Disease Control and Prevention (CDC) regularly conducts a health inspection of cruise liners to help mitigate the incidents of bacterial and viral outbreaks. CDC checks heavily trafficked areas like pools and children's activity centers without any prior notice. Also, inspectors look for vermin, improperly stored food, the dishwasher's water temperature, and the frequency at which the pool's hair and lint strainer is disinfected. Cruise lines are then rated with the lowest scores and the highest scores depending on how well they meet sanitation standards.
Criteria for determining the cleanest cruise ships
The cleanest cruise lines and ships are usually judged based on several factors, including:
- Vessel Sanitation Program inspection scores from CDC
- Staff-to-guest ratio
- Passenger feedback and reviews
- Frequency of cleaning procedures
- Availability of hand sanitizers and hygiene stations
- Quality of food storage and preparation practices
- Maintenance of pools, spas, and recreational facilities
- Air filtration and ventilation systems onboard
- Training and certification of crew in hygiene protocols
- Waste management and water treatment systems
- Response time to illness outbreaks or health incidents
