It is essential for poultry farmers to maintain biosecurity practices to prevent the introduction of the virus. Some of these measures include: - prevent contact between poultry and wild birds - minimise movements around poultry enclosures - maintain strict control over access to flocks by vehicles, people and equipment; clean and disinfect animal housing and equipment. - avoid the introduction of birds of unknown disease status - report any suspicious case (dead or alive) to the veterinary authorities - ensure appropriate disposal of manure, litter and dead animals - vaccinate animals, where appropriate.
