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.

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.
