Salam and hello,
I would like to ask about sterilization method in drinking water in relation to it being CCP in HACCP system.
From what I understand uv-light and ozonation are both sterilization method in drinking water, and a manufacturer can choose either one. However, if a manufacturer have both uv and ozonation in the water treatment system, which one shall be CCP? Can both be CCP if according to decision tree? or ozonation as CCP since it comes after uv?
In terms of validation, the manufacturer need to validate both method or the one identified as CCP?
Also, would having a uv & ozone together is better than having either one?
Thank you very much for your attention!
