I received a customer complaint from a customer that indicated they found glass in product. The object was returned and it is in fact glass. We are a frozen dough manufacturer. We have a glass and brittle plastics registry and aside from lights that are encased in shatter proof casing we do not have glass in the facility. We determined that we would recall all lots for that dough produced on the production date in question. I can't clearly define root cause and don't see a way the contaminant originated in our facility. (I reached out to our suppliers and they have indicated that they have not received any customer complaints and records of sifting/ foreign object detection are in order) I have to complete an FDA report defining root cause, action plan and verification of effectiveness. I also have to submit this information to SQF. I am at a loss as to how to come to a root cause and corrective action to put into place when we still don't know how it entered the facility. Any guidance or assistance would be greatly appreciated!
Thank you for your time,
