Which cleaning materials help reduce cross-contamination?

• A. Disposable paper cloths or colour-coded cloths
• B. Regular cloth towels
• C. Wooden cloths
• D. Metal brushes

Answer: (A)

The main idea is using cleaning materials that minimize transferring contaminants from one surface to another. Disposable paper cloths and colour-coded cloths help with this because each cloth is either single-use (reducing residue that could be carried to other surfaces) or clearly designated for a specific area or task. The colour-coding means you won’t reuse the same cloth across different zones (for example, raw meat vs. ready-to-eat foods), which lowers the chance of cross-contamination. Disposable towels remove the risk of leftover microbes lingering on fabric that gets reused. Regular cloth towels can spread contaminants because they’re reused, so pathogens can be carried from one surface to another. Wooden cloths are porous and harder to sanitize, which lets bacteria persist. Metal brushes can trap debris in bristles and be difficult to sanitize between uses, potentially spreading contamination.
