View Complete Answer & Explanation
Question (English)
Animal should be bled within how many seconds after electrical stunning to avoid muscle splashing?
- 30 seconds ✓ Correct
- 10 seconds
- 60 seconds
- 120 seconds
Explanation:
Correct Answer: 30 seconds
The animal must be bled within 30 seconds after electrical stunning to avoid muscle splashing (petechial hemorrhages in subcutaneous tissue).
Why 30 Seconds?
- After electrical stunning, the cardiac function may still continue briefly.
- If bleeding is delayed, blood pressure build-up can rupture small capillaries, causing 'splash' or petechial hemorrhages in the muscle and subcutaneous tissue.
- Prompt bleeding (within 30 sec) drains the blood before capillary rupture can occur.
Sequence of Events in Humane Slaughter
- Stunning (creates unconsciousness) → within 30 seconds → Sticking/Bleeding.
Stunning Times (for memory)
- Stunning duration: 30 seconds to 1 minute.
- Post-stunning bleed time limit: 30 seconds.
- Electrical stunning current time: 10 seconds (through brain).
