Safety of Airline Metal Cutlery
Received an email from Qatar on how they disinfect the aircraft and associated materials used inflight for our safety in light of the virus outbreak.Came across this section :
All meal service utensils and cutlery are washed with detergents and rinsed with demineralized fresh water at temperatures that kill pathogenic bacteria. All the sanitized equipment are handled by staff with wearing hygienic disposable gloves, while cutlery is individually re-packed.
However, I do recall some airlines, such as Singapore, using polishing machines to "clean" their metal cutlery and not actually using detergent or hot water. Can virus transmission happen as polishing isn't proper disinfection?
