TAMPA -- Officials say six passengers fell ill on a Frontier Airlines flight from Cleveland to Tampa.
WFLA-TV reports health officials boarded the plane when it landed at Tampa International Airport on Tuesday afternoon and the sick passengers were removed.
Officials say they are being held for observation. The sick passengers were not traveling together.
The remaining passengers were kept on the plane for about an hour after it landed. Those passengers deplaned around 4:30 p.m.
Authorities haven't provided information on the symptoms passengers were experiencing or their conditions.
Michele Dynia, communications manager at Cleveland Hopkins International Airport, told FOX 8 News they are taking "precautionary measures" and looking into the possibility that water fountains could be connected to the illnesses. Dynia said water fountains in Concourse A at Hopkins are shut off.
A source told the FOX 8 I-Team that the water quality will be tested Wednesday morning. The source adds there is no definitive link between the water fountain and the illnesses, only that all of the ill passengers may have used the water fountains before the flight.
Frontier released the following statement to FOX 8 on Tuesday evening:
"During Frontier flight 1397 from Cleveland to Tampa this afternoon, six passengers became ill. The aircraft was met by local emergency medical services upon arrival in Tampa. Those passengers displaying symptoms were evaluated by medical staff before being released. All other passengers were released after a brief holding period. The cause of the illness remains under investigation. Passenger safety is Frontier’s number one priority."
