Six passengers fell ill on a Frontier Airlines flight departing from Cleveland with health officials fingering a drinking water fountain as the likely reason.
The passengers became ill en route to Tampa and health officials boarded the plane after it landed .
Airport spokesperson Janet Scherberger said the passengers were not traveling together.
None required hospital treatment, she said.
Meanwhile Cleveland Hopkins International Airport said the drinking water fountains are possibly the source of the illness.
"While the cause of the illness is unknown, an early report from Frontier indicated each of the passengers may have used a public drinking fountain before the flight. Cleveland Department of Public Health is contacting each of the six affected passengers. We are also working to confirm if all six passengers did in fact drink water from the fountain," the City of Cleveland said.
The fountains on the Frontier concourse at the airport were shut down as a precaution.
"The cause of the illness remains under investigation. Passenger safety is Frontier’s number one priority," Frontier said in a statement.
Meanwhile Spirit Airlines is taking no chances and has stopped taking water from the airport.
"Spirit Airlines will not be putting any potable water from the airport on our aircraft until this situation has been resolved," the airline said in a statement.
