Which condition can lead to contamination from overhead plumbing?

The correct answer highlights a critical concern in food safety related to plumbing systems. Grease condensation and leaking pipes can create an environment conducive to contamination. When grease condenses, it can create a sticky residue that can harbor bacteria and other harmful microorganisms. Furthermore, if pipes are leaking, contaminants from the surrounding area can infiltrate the water supply or sanitary system. This situation poses a direct risk, particularly in food preparation areas, where any form of contamination can compromise food safety and public health.

In contrast, clean and well-maintained pipes are essential for ensuring that water systems remain free from contaminants, while insulated piping systems significantly reduce the risks of condensation and temperature-related issues. Low-pressure water systems, while they could pose certain challenges, do not inherently create conditions for contamination in the same way that grease condensation and leaks do. Understanding these risks is vital in maintaining food safety standards and ensuring compliance in a food handling environment.
