To minimize the potential for gastrointestinal disease outbreaks, all passenger 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 accepted standard of sanitation. The latest $($as of

March $2019)$ sanitation scores for $211$ cruise ships are saved in the file $$Sanit$.$xlsx
