Question

At what point is a sanitized surface no longer sanitized, Harris Teeter?

A. Immediately after cleaning
B. After 24 hours
C. After contact with a contaminated surface
D. When visually dirty

Answer 1

A surface is no longer sanitized once it contacts a contaminated surface, because it can be immediately recontaminated. Visual cleanliness does not guarantee sanitation. Regular and thorough cleaning protocols are essential.

Step-by-step explanation:

A sanitized surface is considered to no longer be sanitized once it comes into contact with a contaminated surface. This is because the surface can be immediately recontaminated by pathogens or debris from the contaminated object or substance. The surface may still look clean visually, but if it has been contacted by bacteria, viruses, or other harmful microorganisms, it needs to be cleaned again to ensure that it is truly sanitized. Despite using disinfectants at standard concentrations, surfaces can become quickly recontaminated, thus maintaining a strict cleaning protocol is crucial in environments, especially where bacteria cultures are handled.

Answer 2

The correct answer is option C. After contact with a contaminated surface

Step-by-step explanation:

When considering when a sanitized surface is no longer sanitized, the key point is that it becomes non-sanitary at the moment of contact with a contaminated surface or substance. This could happen immediately after cleaning if something contaminated touches the surface or after a variable amount of time depending on the environment and usage, but there is no exact time such as 24 hours to define it.

Surfaces may look clean visually, but they can still harbor microbes if they have been re-contaminated. It's also important to note that some pathogens are not killed by disinfectants used at standard concentrations, which implies that a risk may persist even after cleaning, depending on the pathogen and the disinfectant used.
