Surface sampling is an important practice in various environments, particularly in pharmaceutical and healthcare settings, to ensure cleanliness and to monitor for contamination. The correct answer indicates that surface sampling should be conducted periodically.

This approach allows for flexibility in the frequency of testing, which can be adapted to the needs of the specific environment. Periodic testing ensures that surfaces are being evaluated at regular intervals without the logistical burden of daily or weekly assessments. This can help in identifying trends in contamination over time and enabling timely interventions if contamination levels rise.

In settings where high cleanliness is crucial, such as sterile compounding areas, periodic testing could be defined by the specific risk levels determined by a facility’s policies. This may mean monthly or quarterly sampling based on factors such as the volume of operations, types of procedures conducted, and prior contamination history.

In contrast, sampling every day or weekly may be excessive for environments that do not have a high risk of contamination, leading to unnecessary expense and resource allocation. Monthly testing might not provide enough data to ensure consistent cleanliness, thus underpinning why 'periodically' serves as the most balanced and context-sensitive choice.
