(11:10 a.m. EDT) -- Cunard's Queen Mary 2 Queen Mary 2 has passed its vessel sanitation re-test, some six weeks after suffering a failing score when inspectors found a human hair in the ice machine, dirty water in the pools and chemicals stored near napkins.

The Cunard Line flagship earned a 92 during the July 27 re-inspection in New York, conducted as part of the Centers for Disease Control and Prevention's Vessel Sanitation Program. The CDC conducts surprise cleanliness exams twice a year; 86 is considered a passing score.

"The company has corrected all issues highlighted by the original inspection, and has subsequently successfully addressed the small number of issues raised by the re-inspection," said Cunard in a statement. The full CDC report, which lists infractions, is not yet live on the government Web site.

Apart from the 84 the Cunard flagship received on June 10, 92 is still the lowest score QM2 has earned since 2004. Last July, the ship nearly aced the exam, earning a 98. "Historically, Cunard ships have achieved high scores and are now on course to re-establish that norm," the line added.

Failing grades for ships, particular the larger mega-vessels trawling the seas, are exceedingly rare. In May, Norwegian Epic came close, scoring a lowly 89, while Carnival Glory squeaked by with an 87 after a January inspection.
