Heating food and water will check diseases except

Options

A. Salmonella infection
B. Cholera
C. Hepatitis -B
D. Botulism.

Answer

To solve the question "Heating food and water will check diseases except," we need to analyze each option provided and determine which disease is not prevented by heating food and water.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which disease cannot be prevented by heating food and water. Heating is known to kill many pathogens, but not all diseases are transmitted through food or water.

2. **Analyzing the Options**:
- **Option A: Salmonella infection**: This infection is caused by the bacteria *Salmonella typhi*, which is transmitted through contaminated food and water. Heating food and water can effectively kill this bacteria, thus preventing the disease.

- **Option B: Cholera**: Cholera is caused by the bacteria *Vibrio cholerae*, which is also transmitted through contaminated water and food. Boiling water and cooking food properly can prevent cholera, making it controllable through heating.

- **Option C: Hepatitis B**: Hepatitis B is a viral infection that primarily affects the liver. It is transmitted through contact with infected bodily fluids (such as blood, semen, etc.) and is not a food or waterborne disease. Therefore, heating food and water will not prevent Hepatitis B.

- **Option D: Botulism**: Botulism is caused by the bacteria *Clostridium botulinum*, which can be found in improperly canned or preserved foods. Heating food properly can kill this bacteria, thus preventing botulism.

3. **Conclusion**: After analyzing all the options, we find that Hepatitis B is the only disease that cannot be prevented by heating food and water. The other three diseases (Salmonella infection, Cholera, and Botulism) can be controlled through proper heating.

### Final Answer:
**Hepatitis B** is the disease that will not be checked by heating food and water.
