OIE animal welfare killing of poultry for disease control


Published on

In January 2012, the OIE gave in Japan an update on the latest developments in killing animals for disease control purposes. The Anoxia method was one of the presented techniques. Today, one year later, the Anoxia technique is commercially available worldwide. Inhumane killing of animals is not longer necessary and the risks of getting infected has been reduced to a minimum.

OIE animal welfare killing of poultry for disease control

  2. 2. Intensions of killing animals for disease control purposes • Protecting human health • Eliminating suffering in diseased animals • Preventing suffering in susceptible animals • Maintaining healthy national heard or flock • Sustaining viable farming / food supply chain 2
  3. 3. Killing methods • Lethal injection of anaesthetics • Maceration – newly hatched chicks / unconscious poultry • Neck dislocation / decapitation of poultry species in small numbers • Electrical stunning and bleeding / electrocution • Gas mixtures – containerised and whole house gassing systems for poultry • Exposure to gas mixture followed by maceration of poultry • Fire fighting foam for poultry • High expansion foam with gases for poultry • Anaesthetics in feed or water - poultry and other birds followed by killing (maceration) 3
  4. 4. During the kill • Staff rotation and counselling • Counselling to animal owners • Interaction with other departments – Transport to deal with traffic diversion – Police to maintain exclusion zones – Weather forecast from met office • Cleaning and maintenance of stunning / killing equipment 4
  5. 5. After the kill • Check all animals are dead Know the important signs of effective stunning and killing methods used in all farm animal species 5
  6. 6. Scientific reports and guidelines Consult American Veterinary Medical Association (AVMA) European Food Safety Authority (EFSA) World Organisation for Animal Health (OIE) 6
  7. 7. Method selection criteria • Nature of disease (e.g. notifiable, zoonotic) or disaster (e.g. floods) • Location of farm • Species, number, size and age of animals • Operators’ health and safety • Availability of resources and expertise • Biosecurity • Cost and efficacy of method 7
  8. 8. Prepare coherent national and state contingency plans Example : Prepare species- and killing methodspecific standard operating procedures 8
  9. 9. Staff training and education • Nationwide planning, co-ordination and execution of control measures during outbreaks • Inform people of their responsibilities and provide necessary training • Mock exercise – like fire evacuation drill in public offices • Identify gaps / inadequacies • Provide education to acquire skills, if necessary 9
  10. 10. Known or established killing methods Two separate presentations: • Poultry species – Mohan Raj • Red meat species – Rasto Kolesar 10
