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

To ask His Majesty's Government, with regard to the independent report Chief Medical Officer’s annual report 2025: infections, published on 4 December 2025, what action they plan to take in response to the specific additional recommendation about the link between agricultural use of novel fungicides and the spread of resistant strains of fungi with the capacity to cause serious disease.

This Government recognises the importance of carefully managing pesticide use, including fungicides, to protect the environment and human health and address the risks of resistance.

During the plant protection product approvals process, the Health and Safety Executive considers the potential for resistance development in the target pest organism. Where resistance is known or anticipated, limitations are placed on product use to mitigate resistance developing. Defra is also funding work by the Agriculture and Horticulture Development Board which provides farmers best practice to minimise the risk of resistance emerging.

Through the National Institute for Health and Care Research, the Department of Health and Social Care has provided over £12 million in funding over the last five years for research into fungal infections and tackling antifungal resistance. Defra has also co-funded a research programme for UK Research and Innovation on ‘Transdisciplinary research to tackle antimicrobial resistance’.

The UK Health Security Agency (UKHSA) is routinely monitoring threats from antifungal resistance. The National Mycology Reference Laboratory performs antifungal susceptibility testing of fungi from human infections from across the UK. UKHSA also monitors antifungal susceptibility testing data for fungal yeast pathogens isolated from blood samples from local microbiology laboratories in England. Trends are published annually.
