Queen Mary 2 fails sanitation inspection

Failing grades for ships, especially the larger vessels, are extremely rare, according to CruiseCritic.com. There have been no failing scores since Albatross, a private ship, received a score of 69 in February 2010, the site reported

The kind of violations found on board the Queen Mary 2 are unacceptable, especially the dirty pool water, said Carolyn Spencer Brown, editor in chief of CruiseCritic.com.

“I’ve been chronicling the CDC scores for 14 years and this one is unusually bad,” Brown said. “What really bothered me was the use of the word ‘filthy’ five times.”

So should you worry if you have a cruise coming up on the Queen Mary 2? Brown said you shouldn’t have second thoughts.

“I’m sure after this, it’s probably the cleanest ship out there,” she said.
