    Press release

    Suspect case of avian flu (bird flu) at Lancashire farm

    From Department for Environment, Food & Rural Affairs
    First published:10 July 2015Last updated:10 July 2015 , see all updates Part of:Animal and plant health

    We are investigating a case of suspect avian flu (bird flu) in Lancashire and movement restrictions have been put in place.

    A temporary control zone has been imposed at a poultry farm in Lancashire in light of a suspect case of avian flu.

    All birds at the premises will be humanely culled as a precautionary measure to limit the risk of disease spread.

    The advice from Public Health England is that the risk to public health is very low. The Food Standards Agency has said there is no food safety risk for consumers.

    The restrictions mean that all poultry farms within the 10 kilometre temporary control zone around the affected premises are not allowed to move poultry and other birds.

    The decision to take precautionary action has been taken based on the clinical symptoms displayed by birds at the farm and emerging laboratory findings. The investigation into the suspect case and laboratory tests are ongoing.

    We have a strong track record of controlling and eliminating previous outbreaks of avian flu in the UK. The outbreaks in Yorkshire last year and Hampshire in February were both successfully contained, allowing restrictions to be lifted at the earliest opportunity.

    Chief Vet Nigel Gibbens said:

    We have taken swift precautionary action to limit the risk of disease spreading. These measures to control the movement of poultry and humanely cull birds at the farm are part of our tried and tested approach to deal with such incidents.

    The advice from Public Health England is that the risk to public health is very low. The Food Standards Agency has said there is no food safety risk for consumers.

    I would urge bird keepers to be vigilant for any signs of disease, report suspect disease to their nearest APHA office and to ensure they are maintaining good biosecurity on their premises.

    Anyone suspecting avian flu (bird flu) should immediately contact their nearest Animal and Plant and Health Agency (APHA) office.

    Up to 170,000 chickens set to be slaughtered after suspected bird flu outbreak

    A control zone has also been set up 10km around a Lancashire farm to prevent any risk of the disease spreading but up to 170,000 laying hens are expected to be humanely culled as a precautionary measure.

    Scientists have yet to discover what strain of flu is involved...
    ...
    The decision to impose a ban on all animal movements around the un-named farm is on based on “the clinical symptoms displayed by birds at the farm and emerging laboratory findings”, say the Department for Environment, Food and Rural Affairs.

    Laboratory tests are ongoing.

      Culling gets under way on Lancs bird flu farm

      Saturday 11 July 2015

      Culling is due to commence on Saturday afternoon (11 July) to take out two layer flocks in Lancashire, following an outbreak of avian influenza on a farm to the north-east of Preston.


      Some 120,000 colony birds and 50,000 free range have been affected and Defra has confirmed that the strain is a H7. But it says it will not be able to confirm the sub-type until tests are completed over the weekend.

      Given that mortality is said to have reached 20% in some of the free-range sheds, and 5% in the colony unit, expectations are that it will be confirmed as a highly pathogenic strain.

      Culling is due to commence on Saturday afternoon (11 July) to take out two layer flocks in Lancashire, following an outbreak of avian influenza on a farm t

        Avian flu confirmed in Lancashire



        From: Department for Environment, Food & Rural Affairs First published: 10 July 2015 Last updated: 13 July 2015 , see all updates Part of: Animal and plant health

        A case of H7N7 avian flu has now been confirmed in Lancashire.






        A case of H7N7 avian flu has now been confirmed in Lancashire.
        A temporary control zone imposed on Friday at the affected farm has now been replaced by a 10 kilometre surveillance zone and an inner 3 kilometre protection zone. Restrictions remain in place and the humane culling of all birds at the farm is continuing.
        Public Health England has confirmed that the risk to public health from this strain is very low. The Food Standards Agency has said there is no food safety risk for consumers.
        The restrictions mean that all poultry farms within the 10 kilometre control zone around the infected premises are not allowed to move poultry, captive birds or other mammals except under licence.
        Chief Veterinary Officer, Nigel Gibbens said:
        Final tests results have confirmed a case of avian flu at a farm in Lancashire. Restrictions put in place last week will continue and the humane culling of all birds at the site is progressing. These actions are part of our tried and tested approach to dealing with previous outbreaks.
        Public Health England has confirmed that the risk to public health from this strain is very low. The Food Standards Agency has said there is no food safety risk for consumers.
        Bird keepers should remain alert for any signs of disease, report suspect disease to their nearest APHA office immediately and ensure they are maintaining good biosecurity on their premises.

            Wild birds believed to be ‘the most likely source’ of Lancashire’s avian flu outbreak

            10:07Thursday 13 August 2015
            ...
            A report issued late last week by a vet working for DEFRA, which also coincided with the lifting of the Protection Zone restrictions imposed around the farm in the wake of the outbreak, states: “The epidemiological investigations indicate that the most likely source of infection was contact with wild species infected with LPAI (low pathogenic avian influenza) followed by a subsequent mutation event to HPAI (high pathogenic avian influenza) that took place on the holding.”

            The report by Dr Nigel Gibbons, Chief Veterinary Officer of the Food and Farming Group, London, also reveals 34,604 birds were infected and died as a result of the virus and a further 145,261 birds were destroyed....
