Which method is recommended for cleaning surfaces to reduce cross-contamination?

• A. Use of disposable paper cloths or colour-coded cloths
• B. Reuse the same cloth across multiple surfaces
• C. Wash surfaces with cold water only
• D. Wipe surfaces with bare hands

Answer: (A)

Preventing cross-contamination comes from using the right cleaning materials and keeping cleaning tasks separated. The preferred method is to use disposable paper cloths or cloths that are colour-coded for specific areas or foods. This helps ensure the same cloth isn’t used on different surfaces (for example, raw meat vs. ready-to-eat areas), so any germs are confined to their designated zone and aren’t carried to other foods or surfaces. Using disposable or clearly labeled cloths makes disposal or laundering straightforward, reducing the chance of spreading contaminants. Why the other options don’t fit: reusing the same cloth on multiple surfaces can transfer germs from one area to another, defeating the purpose of cleaning; washing with cold water only may not remove oils and microbes effectively and won’t sanitize thoroughly; wiping with bare hands risks direct transfer of bacteria to surfaces and foods.
