i have some processing lines which use Xrays... 7 of them and only 4 have Xrays.... and others because of need ( nature of products etc) they do not need xray.... and within those 4 lines with Xrays there is some targeted products that MUST pass thru an xray.. Best practice with Xray is to use stone from country of origin of the product.
Due to nature of the processing (high humidity and heat), the stone and glass do not pick up all the time and we tend to focus on the targeted products and put those on hold and the rest depending on COO and past experience, we let go without re-adjusting.We have tried to correct humidity and heat but we have failed.......To balance my Operational and HACCP needs i have some options which i hope the team will help me with. Due to the nature of the Foreign Object. removal by xray can it be designated as a CP even though you do not have enough for each line? how would you do it when there is constant failure to pick up some challenge test pieces.
Here are my options...
option 1 officially challenge X-ray with metal samples only ( and do stone and glass separately on a different form ) option 2 officially select few products that NEED to be X-rayed and have 2 forms - the official form and the "for reference use only" form which will be for all other products. Procedure will be for any other products we turn off Xray and follow that during the audit - but in real life keep challenging the X -ray
option 3 use market available stone (alumina) during audits, and our stones during any other time..
option 4 use a bigger stone/glass sample- validate your process and with the heat and humidity you can shift your standard as long as you can back it up with data
