Never order iced cocktails on an airplane: flight attendant gave a reason
No matter how tempted you are on board an airplane, don't put ice in your drink, drink coffee, tea or hot water in the lavatory, or touch anything in the toilet.
This was stated by a Reddit user who pretended to be a flight attendant in her viral video. "Ice is put in the tray with a scoop, and the trays are not cleaned very often. Every surface on the plane is touched by hundreds of people every day, and it is not often disinfected. We don't have the opportunity to wash our hands while serving drinks at all," she explained, according to Travel + Leisure.
The fact is that airplanes rarely have ice machines on board, they get ice from third-party services. And, according to a 2017 peer-reviewed study published in the Annals of Microbiology, the ice on board is, frankly, not of the best quality.
The researchers took samples from 60 ice cubes from both domestic and industrial facilities that contained more than 50 different strains of bacteria.
"A constant percentage of the microorganisms found on the ice are known agents of human infections, and their presence is indicative of environmental contamination," the scientists said in their report.
This means that the cubes are probably picking up a dirty substance somewhere along the way from the ice factory to your cup, which brings us to the next point - the ice trays on board an airplane are probably very contaminated.
