The CDC just released the results of the public health inspection of P&O's Oceana on March 1, and the ship failed with a score of only 82. A ship must have 86 to pass.
All of the ship's past inspections have scored at least 95, but the ship isn't in the US often, and it has only been inspected eight times since November 2002. The last inspection before the one in March was January 31, 2012, and it scored 95, but that was more than four years ago. Things have changed since.
The complete story appeared in the April 1 edition of Cruise News Daily.
