Holland America’s ms Oosterdam joins her sister ship Eurodam this year by earning a perfect health score during a routine inspect conducted by the CDC.

Oosterdam‘s unannounced United States Public Health inspection was held on March 3 during a turnaround in Tampa at the beginning of a seven-day cruise to the Caribbean.  Sister ship Eurodam recently achieved her 11th perfect score in January, making industry history with the most consecutive 100s.

Along with Eurodam, six Holland America ships received perfect scores in 2016, including Koningsdam, Maasdam, Veendam, Noordam, and Westerdam.  The year before, seven ships in the fleet received perfect 100s.

CDC inspections are always unannounced and are required for all passenger ships that call in a US port.  They’re performed twice a year for each ship, and scores are given based on a checklist involving dozens of areas of assessment, including food storage, galley cleanliness, water, onboard crew, and the ship as a whole.
