A public announcement was made a day before carrying out culling of birds asking poultry owners not to release the birds in the morning and that veterinarians would collect the birds the next morning against cash payment. Poultry owners were also advised to observe precautions such as cover face, nose etc. when handling the birds. The co-operation of the local bodies is necessary for backyard operations. A common ground was identified for the culling and disposal of the culled birds in consultation with the local bodies. The birds were collected by veterinarian / para-veterinarian in morning & carried to disposal sites.

Waste, organic and all other non-disinfectable material present on the farm -litter , eggs, egg products, hay, animal feed/feed materials, feathers and egg-trays must be destroyed litter can be either buried in the pit with animal carcasses or burnt. Eggs/ Egg products may be buried in the pit with the animal carcasses. Straw may be burnt. The crops grown in the farm should be uprooted and buried/ burnt. The protective clothing used by the staff should also be burnt. Feathers are to be disposed off by use of flame guns. Water should not be allowed to accumulate in the farm premises and particularly in and around disposal sites.

Washing and disinfection of walls, floors and ceilings of the infected . All sheds in the premises should be cleaned which includes washing of floors & walls with 3% calcium hydroxide solution; sprinkling of bleaching powder and lime on the floors of the sheds and farm areas; white-washing of concrete areas with lime; spraying the areas with 4% formalin; fumigation of closed chambers and sheds with KMnO4 and formalin; treating all equipments with 2% sodium hypochlorite solution for 48 hrs Metal structures such as cages may be decontaminated by heat treatment. All units connected to the establishment (i.e. hatchery, egg storage rooms, packaging rooms, egg trolleys, egg product plants) must be properly disinfected. Vehicles, used for transporting live animals, eggs and animal feed must also be disinfected. All equipment inside the house such as drinkers and food hoppers must be washed and treated with a disinfectant for at least 48 hours. Water reservoirs must also be emptied, washed and disinfected. Feed tanks (silos) need to be emptied, washed with a hot water-pressure pump and subsequently fumigated. After washing and disinfecting, all units must be fumigated twice with at least two weeks between fumigations.

Based on Post Operation Surveillance, the farms will be allowed to restock poultry. by keeping sentinel birds in each of the shed of the farms, for 21 days @ minimum 50 birds per shed up to the capacity of 8000 layers or 10,000 brooders or growers and a minimum of 100 birds per shed for more than 8000 layers or 10,000 brooders or growers. 1. On 0 Day Serum sample from 5 birds per shed are to be collected to know the initial antibody status of birds. 2. On the 12 day cloacal / pharyngeal /nasal swabs are to collected for virus isolation. One pooled sample of 5 birds from each shed is to be collected and sent to Bhopal for testing viral antigen/ virus isolation. 3. On 21 day again serum samples from the same birds are to be collected to assess the antibody status of such birds. 4. Any mortality is to be investigated and reported to Govt. of India immediately. 5. It is emphasised that if the farmer does not cooperate and does not follow the restocking protocol he/she will not be allowed to restock the birds. 6. During the restocking operation the local veterinarian is required to visit each farm at least once in a week.

Terminology Biosafety– – In the context of the BTWC, biosafety describes the containment principles, technologies and practices that are to be implemented to prevent unintentional exposure to pathogens and toxins, or their accidental release.
