I am working in a frozen food processing facility that manufactures frozen dough. We perform in house rapid allergen tests for milk, soy and egg allergens as well as ATP. Based on our most recent SQF audit we were told that we should implement an allergen validation utilizing a 3rd party lab. We sent out one round of swabs for all 3 allergens from processing equipment and 1 came back positive for soy. We then sanitized the line again and sent out another round of swabs. This time the results came back positive for milk and soy. Do any of you have any ideas as to how we may be able to revamp our sanitation or allergen programs? Also what would the next steps be? Our current practices do not seem to be helping with the elimination of the allergens. Any information or resources that anyone knows of would be greatly appreciated. Thank you very much!
