(Natural News) No matter how much you love coffee or tea, you might want to avoid asking for it during flights. This is because an unnamed flight attendant for a major American airline claimed that the hot water used for coffee on flights may be unhealthy and unhygienic.

"Don't drink the coffee on airplanes. It's the same potable water that goes through the bathroom system," the unknown flight attendant told the website Vice.com.

The flight attendant further explained that their airline had a test for E.coli in their water and it did not pass.

"And then maintenance came on and hit a couple [of] buttons and it passed," the flight attendant said.

The anonymous flight attendant advised to avoid any hot water or tea, and to instead ask for bottled water or ice.
