My facility is interested in beginning production of a 70% organic ("made-with-organic...") version of our product along side our non-organic product (parallel operation). We use a salt in our non-organic product that contains YPS, a prohibited substance in organic products. We mix the salt into a slurry in a mix tank that would also be used to mix the organic slurry. To perform a change-over currently, we empty the lines & perform a water rinse of the tank & lines, followed by a rinse with oil, an then another water rinse. After speaking with a certifying agency, they said that that same change-over process would likely be okay for changing over to organic product as long as we validate it. This is where I get stuck.


Would ATP swabbing, considering the ingredients going into the tank (refined oil + others), be applicable for this situation or is there another rapid test that can be performed to ensure no prohibited substances remain for organic production?


Thank you!

Hi Bailey39,


I would look to validate your changeover procedure by having the first organic product off analyzed for YPS whilst at the same time recording your ATP results & rinse setting (times/flow/volumes etc.).


This way in the future you can verify rinse is satisfactory using ATP knowing you have analysis that proves the rinse is effective. I am assuming that product residues will be detected effectively by ATP?


Also if you CIP then organic would normally be the first product off to further reduce the risk of cross-contamination.


Kind regards,
