Cruise Carnival Triumph graded 'unsatisfactory' after sanitation inspection By Tom Stieghorst / January 02, 2018 Share 1 Photo Credit: cdrin/Shutterstock -- The Carnival Triumph was graded 78 on a sanitary inspection by the U.S. Centers for Disease Control in November, receiving an "unsatisfactory" rating from the agency. Cruise ships must score 86 or above on a scale of 1 to 100 to receive a satisfactory rating.It is relatively rare for large cruise ships that sail regularly in the United States to grade out unsatisfactory. The Carnival Triumph had never before earned a failing grade in inspections dating back to 1999.The report cites backflow prevention devices that were corroded, water dripping from ceilings onto food boxes, hand washing stations where the water isn't warm enough and dead flies in several food and beverage areas, among other infractions.The crew said that there was a waterline break on the day of the inspection, the report said.In a statement, Carnival Cruise Line said it took steps to fix the cited problems immediately and has filed a corrective action report with the agency. "On the extremely rare occasion when one of our ships has an unsatisfactory score, we initiate immediate and aggressive corrective action and closely examine the factors involved to ensure full understanding among all team members," a Carnival statement said.Carnival added it has requested a re-inspection as soon as possible.Other ships graded unsatisfactory this year by the CDC are much smaller than the 3,140-passenger Triumph. They include Ponant's Le Boreal, which received a score of 84 in an October inspection, and Victory Cruise Line's Victory I, which was graded 78 in June.
