Workers at mechanical-biological waste treatment plants in Poland are routinely breathing in air laden with dozens of bacterial species and antibiotic-resistance genes, as revealed by DNA sequencing of their vehicle cabin filters — posing serious occupational health risks that existing safety standards may not adequately address.
34 bacterial species were detected at meaningful levels across 9 vehicle air filters sampled at Polish waste treatment facilities in summer 2024
Antibiotic resistance genes (ARGs) were found covering drugs used exclusively in human medicine, in both human and veterinary medicine, and drugs not approved for human use at all
DNA next-generation sequencing revealed high bacterial species diversity even in this small sample, suggesting the threat is likely broader than previously measured
