Carnival Cruise Line has reason to be very happy. More reason than Cunard Line, who was highly embarrassed earlier this month when their flagship, the Queen Mary 2, failed a surprise health inspection in the port of New York.

For the first time ever, two cruise ships belonging to Carnival achieved perfect health scores during an inspection by the U.S. Public Health department – on the same day.

The guys over at Cunard are no doubt green with jealousy over their colleagues’ good luck.

The two lucky ships are Carnival Paradise and Carnival Glory, who both earned a 100% score during inspections carried out in Long Beach California and New York respectively.

Both cruise liners had to pass the 42-point comprehensive Vessel Sanitation Program checklist. What makes it even more tricky is that these inspections are unannounced and carried out twice a year. Every cruise ship that docks at a U.S. port as part of an international itinerary has to undergo such an inspection.

The inspectors look at issues such as proper food handling, storage and preparation procedures and the overall level of hygiene of the galley. They also evaluate the water supply in the ship’s pools and spas.

The 2,052 passenger Carnival Paradise is currently offering a range of three and four-night Baja cruises departing from Long Beach, California. The Carnival Glory, with a passenger capacity of 2,974 passengers, is sailing from New York on a series of four to seven-day cruises to New England and Canada.
