Question (English)
Lime water (1:20) or suspension of bleaching powder (1:20) is mainly used in which method of carcass disposal?
- Burial
- Incineration
- Chemical method ✓ Correct
- Rendering
Explanation:
Correct Answer: Chemical method
Lime water (1:20) or suspension of bleaching powder (1:20) is used in the chemical method of carcass disposal. This method is employed when burial or incineration is impractical.
Chemical Method Details
- The carcass is placed in a pit and covered with quicklime (calcium oxide) or bleaching powder solution.
- Ratio: 1 part lime/bleaching powder to 20 parts water (1:20).
- Lime raises the pH drastically, destroying most pathogens and accelerating tissue decomposition.
- Less reliable than incineration for spore-forming organisms like Bacillus anthracis.
Comparison of Disinfectants Used in Meat/Abattoir Science
| Disinfectant / Chemical | Concentration | Use |
|---|---|---|
| Lime water / Bleaching powder | 1:20 | Chemical carcass disposal |
| Chlorine | 130–250 ppm | Abattoir sanitation |
| Formalin | 10% | Disinfection of anthrax surroundings |
| Phenol | 5% | Disinfection of anthrax surroundings |
