Whole Flock Health Scheme

Poultry farmers must operate under a Whole Flock Health Scheme (WFHS). Find out what a WFHS is and what it needs to have.

What is a Whole Flock Health Scheme?

A Whole Flock Health Scheme (WFHS) is a written programme for health surveillance. It includes information about any actions taken to control or eradicate disease and to manage:

  • agricultural chemicals
  • veterinary medicines
  • feed and environment contaminants. 

What you need to record

Your WFHS should record:

  • any medications or immunisations given to the flock or individual birds
  • feeding regimes
  • visits by veterinarians or ante-mortem examiners (people who test live poultry for safety, suitability, and disposition)
  • other individual or flock diagnostic results that establish and verify the health status of the individual or flock
  • any microbiological results (including for Salmonella and Campylobacter)
  • any other information that helps establish and verify the health status of your flock.

Sample WFHS 

You can find an example of a WFHS in Appendix C of the Generic RMP for slaughter and dressing of broilers [PDF, 644 KB]

Note that farmers don't need to have a risk management programme (RMP), just a WFHS.

For maximum permissible levels of residues (pesticides, antibiotics, and contaminants), refer to the Animal Products Notice: Contaminant Specifications 2016 [PDF, 864 KB]
