I have an issue and i need some help.......
I am currently trending my forign body findings and i am currently running at 78% of findings in metal contaminated product rejected by the metal detector. What my issues are: I have probably located the source to the mixer on the mince lines, the blades are chipping off due to using frozen blocks of vl @ a temperature of -6 to -8. I have made engineering and production aware and the answer i get is " good job we have a metal detector then" also the business is aware of the issue but nothing is going to happen until something happens i.e. complaints etc.
Surely with turning a blind eye, section 3.8 Corrective actions & preventative actions requirement of BRC could be effected when it comes to audit in 8 weeks time.
Please advise
Thanks 
The way I read this and correct me if i am wrong is that knowingly 22% of metal that comes off the blades is going out for consumption?.
What standard do your metal detectors work to in relation to test pieces, IMEX in mince its hard to get better than 2.5mm SS and given you might get wire type shavings you could have some large pieces of metal going out.
You could wait for the corrective action or consumer complaints, which could be quite nasty. Personally I would try to build a case to win over the senior leadship on site. I would try to get some big examples of metal that cannot be found by the
metal detector to present. If you are working on 2.5mm SS the
metal detector would struggle with wires 2.0m x 6.0mm IMO.
IMO metal detectors are there to alert you of an issue, not clean the product as so many think. Some examples of what cannot be found may hit home.
Good luck
