Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, what steps his Department is taking to improve the regulation of wastewater treatment processes to reduce the levels of (a) pharmaceuticals, (b) microplastics and (c) per- and polyfluoroalkyl substances entering the (i) environment and (ii) food chain.
Answered by Emma Hardy - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
The Environment Agency works with the water industry on the Chemicals Investigation Programme (CIP). This is funded through the water industry price review and considers chemicals in sewage effluent, including some pharmaceuticals and Per- and polyfluoroalkyl substances (PFAS). The fourth CIP has just started.
Regulation does not currently cover microplastics from treated wastewater. 99% of microplastics are removed by sewage treatment processes. The EA and water industry are commencing six investigations under CIP considering generation of microplastics within wastewater treatment works through attrition of plastic equipment, emerging sewage treatment technologies and path of microplastics from biosolids applied to land to soils and groundwater.
The EA sits on the Pharmaceuticals in the Environment Group. Pharmaceuticals are not required to undergo an environmental impact assessment, but a few have ecotoxicological thresholds that inform an assessment of potential risk. The EA Is currently investigating potential ecological risks of mixtures of pharmaceuticals in the aquatic environment.
CIP4 is looking at PFAS from wastewater treatment works. CIP2 identified domestic sewage as a significant source of PFAS. On-going work includes identifying sources of or Perfluorooctanesulfonic Acid (PFOS), a type of PFAS, in catchments to inform approaches to permitting discharges, and to reduce/eliminate PFOS at source.

Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, what steps he is taking to (a) help prevent the dairy-cattle H5N1 virus strain from (i) entering and (ii) spreading among the UK population and (b) prepare for potential outbreaks of that virus in UK cattle.
Answered by Daniel Zeichner - Minister of State (Department for Environment, Food and Rural Affairs)
The Government is in close contact with counterparts in the United States on the incidents of influenza of avian origin in cattle in the USA. We know that the strain of virus (Highly Pathogenic Avian Influenza (HPAI) strain B3.13) involved has not been detected in the UK from our bulk milk testing and wider surveillance.
Defra is working closely with the Department of Health and Social Care (DHSC), the UK Health Security Agency (UKHSA), the Food Standards Agency (FSA), the Cabinet Office and with international partners to consider the potential routes of incursion, evidence of animal-to-animal spread and risks of animal-to-human spillover and to reviewed our well-tested surveillance and preparedness activities to detect and respond to any infection of cattle from influenza of avian origin in the future.
The Animal and Plant Health Agency (APHA) has assessed the risk to livestock in Great Britain from this outbreak of Influenza A (H5N1) of avian origin in livestock in the USA, as very low (event is very rare but cannot be excluded) (Avian influenza in cattle in USA (publishing.service.gov.uk). The FSA have assessed the risk to UK consumers from HPAI strain B3.13 in imported milk, dairy products, colostrum and colostrum-based products originating from US dairy cattle as very low with medium uncertainty (Rapid Risk Assessment: Risk to UK consumers from Highly Pathogenic Avian Influenza (HPAI) H5N1 B3.13 in US dairy products | Food Standards Agency). The Human Animal Infections and Risk Surveillance group (HAIRS) consider that the HPAI B3.13 strain presents at most a very low risk with regard to spread from animals-to-humans in the UK HAIRS risk statement: Avian influenza A(H5N1) in livestock - GOV.UK (www.gov.uk).
Defra has funded a research consortium at led by The Pirbright Institute and Imperial College to understand this unusual situation. In addition, we have published an Influenza A (H5N1) infection in mammals: suspect case definition and diagnostic testing criteria’ on gov.uk to support veterinary professionals and others in knowing when to report suspicion.
