OIE animal welfare killing of poultry for disease control

IMPROVED ANIMAL WELFARE PROGRAM (IAWP)

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

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)

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

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

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

8

Prepare coherent national and state contingency plans

Example:

Prepare species- and killing method-specific standard operating procedures

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

Known or established killing methods

Two separate presentations:

• Poultry species – Mohan Raj• Red meat species – Rasto Kolesar

Poultry: Neck dislocation

12

Waterfowl: neck dislocation

Poultry: Captive bolt

Cartridge

Compressed air

14

Head-only electrical stunning followed by bleeding or neck dislocation

15

Mobile electrocution (water bath)

16

Gas mixtures

Carbon dioxide has been used in,

Skips and waste bins

Modified Atmosphere Killing (MAK) Carts

Containers

17

Dry ice in a bag

18

Gaseous CO2 in skip and bin

19

Containerised Gassing Unit (CGU)

20

Mobile gaseous killing units

21

Mobile CO2 system

22

Whole house gassing (WHG)with CO2

23

WHG battery cage

24

Carbon monoxide

Whole house gassing with CO has been tested in the Netherlands and Belgium

Used in South East Asia

There are serious animal welfare concerns
