Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government what assessment they have made of (1) agricultural composting facilities, (2) green waste, and (3) crop residue piles, as potential reservoirs for azole-resistant Aspergillus fumigatus; and what plans they have to improve surveillance of that issue.

In support of antimicrobial resistance (AMR) national action plan commitments, the Environment Agency (EA) actively carries out research into environmental transmission and risks associated with antimicrobial resistance. This includes research on monitoring antifungal resistance and bioaerosols.

The EA recognises the potential human health impacts of bioaerosols, particularly on the respiratory system. The EA actively regulates bioaerosol risks from waste treatment, including open composting of green wastes and digestate fibres. Regulated activities must hold a permit. Higher risk facilities monitor bioaerosol emissions including aspergillus fumigatus. These controls developed from over a decade of research collaboration with the EA, academia and industry.

External crop residue storage (non-waste) at anaerobic digestion (AD) sites does not require a permit. However, Defra has recently concluded a consultation on regulatory reform to include non-waste AD facilities. The reform has potential scope to align non-waste AD with regulated waste AD under the Environmental Permitting Regulations.
