Hazard | Welfare consequence/s occurring to the cattle due to the hazard | Hazard origin/s | Hazard origin specification | Preventive measure/s of hazards (implementation of SOP) | Corrective measure/s of the hazards |
---|---|---|---|---|---|
Restraint | Pain, fear | Staff, equipment | Lack of skilled operators, immobilisation of the animal and presentation of the head of the cattle to the operator are required |
Careful selection of operators, staff training Use of passive head restraint or use optimum pressure according to the size of animal |
Keep the duration of restraint to the minimum |
Incorrect shooting position | Pain, fear | Staff | Lack of skilled operators, operator fatigue, poor restraint, wrong target area or angle of shooting, inappropriate placement of the gun due to the shape of the head | Staff training and rotation, appropriate restraint of the animal, proper placement of the gun | Stun in the correct position or apply a different killing method |
Incorrect captive bolt parameters | Pain, fear | Staff, equipment | Lack of skilled operators, wrong choice of equipment, inappropriate cartridge and power, poor cleaning and maintenance of the equipment, too narrow bolt diameter, shallow penetration, low bolt velocity | Staff training, appropriate restraint of the animal, ensuring equipment is fit for the purpose, regular cleaning and maintenance of equipment | Stun with correct parameters and/or apply a different killing method |
Overheating of the gun | Pain, fear | Staff | Lack of skilled operator, lack of sufficient number of captive bolt guns, lack of resting of captive bolt gun to cool | Staff training, ensuring sufficient number of captive bolt guns are available and rotation of captive bolt guns | Rest overheated captive bolt gun for the barrel to cool off |
Prolonged stun‐to‐kill interval | Pain, fear | Staff | Lack of skilled operators, too long time between stunning and killing | Staff training, prompt and accurate application of a killing method | Re‐stun and apply a killing method |
Sublethal dose of chemical used as a killing method | Pain, fear | Staff | Lack of skilled operator | Training of staff, ensure lethal dose of chemical | Apply lethal dose |
Disposal of cattle while alive | Pain, fear | Staff | Lack of monitoring, too fast operation | Ensure death by proper monitoring of signs of life before disposal | Re‐apply a killing method |
ABMs: signs of consciousness, attempt to regain posture (consciousness), signs of life (not dead), escape attempt (pain, fear), injuries (pain), vocalisations (pain, fear) |
