MOSCOW, 5 Dec — the drinks served aboard the aircraft may be dangerous to human bacteria, because water tanks are not cleaned properly.
“The planes land, but after that tank nobody cleans because there’s no time. Again fill them to the brim. Everything that settles to the bottom, there”, — said the publication New York Post, Professor at Hunter College in new York Charles Platkin.
The passengers, fearing microorganisms such as Escherichia coli, do not drink coffee or tea prepared on Board, said the scientist. It is also recommended to use their own sanitizers after visiting the toilet.
