Answer 1

The Correct Option is B

Step 1: Concept
Cleaning and Disinfection in Food Processing

Step 2: Meaning
Cleaning involves the removal of visible soil, organic matter, and other contaminants from surfaces. Disinfection is the process of reducing or eliminating microorganisms on surfaces.

Step 3: Analysis
- Cleaning before disinfection ensures that any visible soil and organic matter are removed first. - Visible soil can shield microorganisms, making them harder to eliminate with just a disinfectant. - Removing this soil makes it easier for the disinfectant to reach and effectively kill microorganisms. - Options A, C, and D do not directly address the primary purpose of cleaning in relation to disinfection.

Step 4: Conclusion
The primary purpose of cleaning before disinfection is to remove visible soil that shields microorganisms from being properly disinfected. Final Answer: (B)
