Looking for some input on environmental testing after a sample comes back positive, an investigation is completed, and a corrective action is completed (in this case a deep clean):
Should you re-swab the impacted area immediately or wait to re-swab until after a predefined time into production?
I understand that swabbing immediately poses a risk to indicate the organism has been removed even though it hasn't, but waiting a predefined amount of time may allow the impacted area to be recontaminated again from another source. I'm thinking like an area on the floor that is being impacted by boot traffic from another area that has yet to be discovered. Resulting in expending resources in an area while allowing the actual problem to go unchecked.
Again, I also understand the allure of sampling immediately as it will certainly have a higher likelihood to pass even if the organism hasn't been completely destroyed. Thoughts?
