The Correct Option is D
Solution and Explanation
During a disease outbreak, it is crucial to ensure accurate bacteriological examination of water samples. Proper collection techniques help prevent contamination and ensure reliable results. Follow these steps for collecting water:
- Choose a proper tap or outlet, avoiding those that are already leaking. Existing leaks can introduce contaminants, affecting the sample integrity.
- Let the water flow for at least 1 minute before collecting the sample. This helps flush out stagnant water and contaminants that may have settled in the pipes.
- Hold the water sample container close to the tap but maintain a careful balance to avoid spillage and unnecessary exposure to external air contaminants.
- Most importantly, collect the water from a gentle stream to avoid splashing. Splashing can introduce external contaminants and disrupt the sterility of the sample.
This method ensures a higher accuracy in detecting bacterial pathogens, essential during an outbreak investigation.
