2.24 Sanitation inspection of cruise ships. To minimize the po- tential for gastrointestinal disease outbreaks, all passenger SANIT cruise ships arriving at US ports are subject to unannounced sanitation inspections. Ships are rated on a 100-point scale by the Centers for Disease Control and Prevention. A score of 86 or higher indicates that the ship is providing an ac- cepted standard of sanitation. The latest (as of March 2019) sanitation scores for 211 cruise ships are saved in the accom- panying file. The first five and last five observations in the data set are listed in the accompanying table.
