Disinfectant for FMD Outbreak
Disinfectant of choice at the time of FMD outbreak is:
- 4% Na₂CO₃ — Correct Answer
- 5% NaCl
- KOH
- HCHO
Explanation:
Correct Answer: 4% Na₂CO₃ (Sodium Carbonate)
4% Sodium Carbonate (Na₂CO₃) is the disinfectant of choice during Foot and Mouth Disease (FMD) outbreaks. It is also known as washing soda or soda ash.
Other Disinfectants/Chemicals Used in Animal Management
- 4% Na₂CO₃: FMD outbreak disinfection
- KOH (Caustic Potash): Chemical dehorning in calves
- 30% Tincture Iodine: Navel cord treatment in newborns
Note on FMD
FMD is a highly contagious viral disease affecting cloven-hoofed animals (cattle, buffalo, sheep, goat, pig). Foot-bath with disinfectant is provided at the entrance of the farm to control spread.
Why Other Options Are Wrong
- 5% NaCl: Common salt solution — not effective against FMD virus.
- KOH: Used for chemical dehorning, not FMD disinfection.
- HCHO (Formaldehyde): Used as a preservative/fumigant, not the primary choice for FMD.
