Carnival Dream scored 100 during its most recent United States Public Health (U.S.P.H.) in Port Canaveral, Fla., marking the third time that a Carnival ship has earned a perfect score this year.

To earn a 100 score, cruise ships must receive perfect marks on all 42 items that comprise the U.S.P.H.’s comprehensive Vessel Sanitation Program checklist. The unannounced inspections, which are conducted twice a year and required for any cruise ship with an international itinerary calling at a U.S. port, evaluate vessels in a wide variety of areas, including adherence to proper food handling, preparation and storage procedures, and overall galley cleanliness. Ships’ potable water supplies used in spas and pools are evaluated, as well.

The 3,646-passenger Carnival Dream will operate five- to eight-day Caribbean departures from Port Canaveral before repositioning to New Orleans for year-round seven-day Caribbean cruises beginning in April 2014.
