- Bone darkening
Explanation:
Correct Answer: Splash
Splash (also called 'muscle splashing') refers to the appearance of petechial hemorrhages (tiny pinpoint bleedings) throughout the subcutaneous tissue of pigs, caused by too high electrical current during electrical stunning.
Defects of Electrical Stunning at a Glance
- Splash: Too high current → petechial hemorrhages in subcutaneous tissue of pigs.
- Missed shock: Too low current → animal inadequately stunned, regains consciousness.
Prevention
- Use correct parameters: 250 mA, 75 volts, AC, for 10 seconds.
- Bleed the animal within 30 seconds of stunning to prevent splash.
Context: Physical Changes in Stored Meat
- Shrinkage: loss of weight during storage.
- Sweating: condensation of water vapour on meat brought from cold store to room temperature.
- Loss of bloom: loss of bright red colour of fresh meat.
- Splash — occurs at slaughter stage, not storage stage.
