Cross contamination can occur when which condition exists?

• A. Use of separate cutting boards for raw and cooked foods
• B. A hose left submerged in the mop bucket
• C. Proper cleaning of surfaces
• D. Keeping raw and cooked foods separate

Answer: (B)

Cross contamination happens when harmful microorganisms are transferred from a dirty source to a clean surface or ready-to-eat food. A hose left submerged in the mop bucket creates a clear risk because the mop water is dirty and can flow back into the water supply or splash onto food-contact surfaces and utensils. This setup gives contaminants a direct route to foods, increasing the chance of transfer. The other practices—using separate cutting boards for raw and cooked foods, keeping raw and cooked foods apart, and thoroughly cleaning surfaces—are all ways to prevent contamination, not introduce it.
