How testing plane toilet waste could detect emerging threats
Aircraft toilets could hold key to fighting superbugs
A study has found that testing aircraft toilet waste can help monitor the global spread of drug-resistant superbugs, often referred to as the “silent pandemic”.
Scientists analysed lavatory wastewater from 44 international flights arriving in Australia, detecting nine high-priority pathogens and superbugs.
An antibiotic-resistance gene, not previously found in Australia’s urban wastewater, was detected on 17 flights, suggesting its likely entry into the country through international air travel.
Flights originating from Asia, particularly India, showed higher concentrations of antibiotic resistance genes compared to those from Europe and the UK.
This research indicates that aircraft wastewater monitoring could serve as a valuable early-warning system for emerging superbug threats, complementing existing public health surveillance.
