Seven crew members aboard a cruise ship headed to Baltimore on Saturday were sickened by carbon monoxide poisoning, rescue officials said.
Fire department crews and a hazmat team met the Celebrity Mercury when it docked in Baltimore to treat the victims and search the 12-year-old ocean liner for the cause of the leak, fire department spokesman Chief Kevin Cartwright said.
The crew members were poisoned while the ship was in transit, Maryland Port Administration spokesman Richard Scher said.
"Obviously, it is being looked at carefully," Scher said.
Further details on the conditions of the crew members were not available Saturday. Representatives of Celebrity Cruise Lines could not be reached for comment.
