Following an intensive inspection by a team of U.S. Public Health officers, Crystal Cruises’ ultra-luxurious, award-winning Crystal Symphony received a “perfect” score of 100 from the Center for Disease Control and Preventions (CDC). The audit occurred during Crystal Symphony’s October 21 call in Boston, Massachusetts.

Scoring is based on 41 inspection items of the potable water system; food preparation and storage areas; waste management systems, including filters, ventilation devices and sanitizing temperatures; cleaning sequences and standards of accommodations and public areas; and general environmental health issues. Swimming pools and spas are also inspected.

The CDC developed its Vessel Sanitation Program (VSP), which operates under the U.S. Public Health Service Act, to inspect all cruise ships that offer foreign itineraries with U.S. ports, and assist the cruise ship industry in the implementation of systems to protect the health of travelers. Under the VSP, cruise ships are subject to unannounced health inspections.

Crystal Serenity also received a perfect 100 during her most recent call in Canada in May.

“Crystal Cruises’ record of perfect scores is indicative of our efforts to meet the highest standards of excellence in all areas of our cruise operation,” says Joe Valenti, Crystal Cruises’ senior vice president, marine operations.

Earlier this month, Crystal Symphony emerged from drydock with freshly redesigned Crystal Penthouses and Penthouse Suites, elegant Lido Café and Prego Italian restaurant and completely transformed pool deck, among other transformations. The $25+ million makeover reinforces Crystal’s commitment to delivering a product that consistently earns the industry’s top accolades. Likewise, the Public Health recognition comes just weeks following the line’s record 16th year voted “Best Large-Ship Cruise Line” by the readers of Condé Nast Traveler.
