Which situation is considered a potential hazard in water supply and plumbing?

• A. Non-potable water contacting food
• B. Safe source and treatment
• C. Ice from potable water
• D. Suitable temperature and pressure

Answer: (A)

The key idea here is the risk of a cross-connection between non-potable water and food or food-contact surfaces. Non-potable water may carry pathogens, chemicals, or other contaminants. If it comes into contact with food or with equipment that touches food, those contaminants can transfer to the food and create a safety hazard. That’s why non-potable water contacting food is considered a potential hazard in water supply and plumbing. The other scenarios describe safe or acceptable conditions: a safe source and treatment means the water is properly treated and not a hazard; ice made from potable water uses drinking water, which is acceptable when produced under sanitary controls; and having suitable temperature and pressure are operational parameters that support safety but do not themselves introduce contamination.
