The new Costco audit guidelines require that companies use X-ray as part of the foreign material program. However, in our process we use metal detector because based on the ingredients and process is the most likely hazard to occur. If there any potential of plastic contamination are thin plastic bag pieces that I read can't be detected with a x-ray and for which we have controls to ensure minimize the risk.
So, for the following audit I need to find an expert on this matter to have the letter before the next audit. sooner the better.
Thank you for your help.
