( CNN ) -- Federal health officials are investigating another possible norovirus outbreak aboard a cruise ship that just ended a Caribbean voyage . The U.S. Centers for Disease Control and Prevention reported that 114 passengers and 10 crew members on the Holland America cruise ship ms Veendam suffered vomiting and diarrhea during a week-long voyage that ended Saturday . A CDC Vessel Sanitation Program environmental health officer and an epidemiologist boarded the ship when it arrived in Fort Lauderdale , Florida , on Saturday , the agency said . The investigators will `` conduct an environmental health assessment and evaluate the outbreak and response activities . '' The CDC is also testing stool samples from the sickened passengers and crew , the agency said . Holland America officials did not immediately respond to requests for comment . The Veendam carried 1,273 passengers and a crew of 575 , the CDC said . Hundreds of people aboard two cruise ships in the Caribbean fell ill with norovirus last month . The CDC reported that norovirus hit more than 600 passengers and crew on Royal Caribbean 's Explorer of the Seas in January , making it one of the biggest such outbreaks on any cruise ship in the past two decades . The Caribbean Princess , operated by Princess Cruises , cut short its seven-day Caribbean itinerary last month after 178 passengers and 11 crew members were stricken with norovirus . CDC staffers helped sanitize that ship . The Veendam got a failing grade from CDC inspectors who found multiple sanitation violations , including brown liquid dripping on clean dishes and a fly on the buffet , in September , the CDC said . `` While unacceptable for Holland America Line , the unsatisfactory score is highly unusual and an aberration , '' Holland America 's Sally Andrews said last year . Inspectors do n't tell cruise lines when they 're going to show up , but they visit twice a year as part of the CDC 's vessel sanitation inspection program . The CDC grades ships on a 100-point scale . An 85 or lower is considered a failing grade . The Veendam received a grade of 77 . `` Since 1996 , Veendam has received passing scores on 32 inspections , '' Andrews said . The Veendam is a 16-year-old ship , christened by actress Debbie Reynolds , that can carry 1,930 passengers and crew , according to Holland America .
