  • All the farm should adopt a vigilance system for early detection of suspected cases of the disease and for appropriate follow up action. It would be desirable that different teams are constituted to visit different pans of the farm.
  • These teams should adopt strict disinfection procedure along with protective clothing, gloves, mask & caps etc. during their visit and undergo a complete disinfection procedure before moving into the next pan.
  • Any suspected case detected by the vigilance team should be reported to the farm authority and to the state veterinary department immediately for any support needed by the farmer, breeder or farm.
  • The suspected flock should be quarantined in-situ by imposing all the disinfection procedure and stopping any exchange of material from that locality to other parts of the farm and outside of the farm. Follow up action may be taken as per the advice of the department of veterinary services or animal husbandry or a qualified veterinary officer of the state department.
  • In the event of detection of infection in the flock of the suspected disease the entire operation of the farm in terms of marketing of produce, birds, eggs etc. should be stopped completely till the disease passes off. This regulatory mechanism will be in force till one month of the last case detected in the said farm.
  • All such poultry farms, breeders and farmers should stop immediately entry of new birds in the flock from outside sources and from sources of unknown diseases status. Before allowing entry of new stock it should be ensured that similar type of disease has not occurred in the supply farm at least within 3 months period.
  • The farm which has encountered this disease and no clinical cases have been detected should not move the birds out of the farm before expiry of thirty days period with verification of the fact by the state government veterinary officer.
  • In order to provide immediate help and support to the farms, poultry breeders and farmers the State authority should gear up the emergency responsive system as per exigencies under intimation to the Chairman of National Animal Disease Emergency Committee and Secretary, Department of Animal Husbandry & Dairying, Government of India.
  • The state government should draw up a plan to monitor and regulate the movement of birds and other produce from this poultry farm located in the infected belt so as to minimise the risk of spread of the infection to the other parts of the country.
  • If necessary, state government should take recourse to the state legislative provision/ Act available for this purpose. In the event of detection of infection / outbreak in any farm the follow up action will be taken as per direction of the state authorities. The cullers should use goggles, impervious aprons, gloves, gum boots and face masks. State Government should organise awareness camps related with various poultry diseases.
