Hello !!! We are a juice bottling facility. Our bottle filler gets manual clean, CIP (which includes sanitizer) and then it is ATP swabbed. We have a 9 RLU limit on ATP. As of recently we have been seeing a lot of failures in our ATP and I have been approving a few of them because it is time consuming. They would just re-spray with sanitizer and re-swab and the level would either go UP (despite spraying with sanitizer) or remain the same with a slight decrease. We use OXINE sanitizer at levels of 15-30oppm. As of recently they are failing wayy to much and it has been a hassle on identifying the root cause. We have been taking a few action plans as in replacing any brushes they manually clean with often. We obviously monitor the sanitizer as well. After reading a few online articles, I have come across as ATP readings can also come from product residue, especially organic. Has anyone fell into this? Also I read that ATP swabbing occurs BEFORE sanitizer and after cleaning. Some parts are not really CIPed with the filler bowl, rather they are manually cleaned and sanitized with Oxine. These parts are always HIGH in ATP almost all the time. I am thinking it is due to the sanitizer that is leaving organic residue, affecting ATP counts? Here is what I am reading, from this article linked below. If anyone has been through this, I would love some feedback and what did they do. "If a sample has an increase in organisms or organic residues, there will be an increase in ATP, and therefore an increase in RLUs." https://food-safety-...handling-areas/
