No one wants to be stricken by a nasty gastrointestinal virus on a cruise. So to keep the traveling public informed, the Centers for Disease Control and Prevention inspects ships and publishes the results. A score of 85 or lower is consider a “fail.”

Some of the ships on this list are obscure charter operators, but others are familiar to anyone who cruises.

So, without further ado, here are the winners … I mean, losers. (I’ve included an excerpt from the report for your reading enjoyment.)
