Metal detector rejects: Is Root cause analysis necessary for every rejection?
Hi everyone,
I was wondering if for every rejection by the metal detector(MD), the rejected product should be taken through a root cause analysis.I think it should because the product with the metal contaminant has now become a non-conforming product hence the detection and rejection by the MD. The MD is supposed to detect and reject (actually means the control measure in place is working) but then should'nt we be conducting a root cause analysis to prevent recurrence of the presence of metal contaminants in the products?
What's your take on this.
Thanks.

Hello AngieGH,
You are aboslutely right about MD rejection but you won't get a root cause for the rejection itself, you will inspect the rejected quantity and then do root cause analysis for the FM that made MD did the rejection.
Example: your MD rejected specific quanityt of product and by inspection you found a metal piece 3mm, then you shall your factory team to get the root cause and know the source of this FM ( this step is a type of improvement for CAPA , preventive maintenance and monitoring itself of IPC plus HACCP).
Hope that i could help you!
Thanks M.Yusuf.
I get you right, the rejected product must be taken through root cause analysis.
Thanks.

Standard ??
Hello AngieGH.
yes! it is a deviation of a CCP,

Are we speaking of actual metal inclusion rejects or all rejects?
99.9% of our MD rejects are false positives. We deal with moisture and frozen form variances in our product which has been documented in our validation study for reject thresholds and verification standards. I can't imagine performing RCA/CAPA for all...

Hi, Leila;
If the metal detector is a monitoring instrument, and during this monitoring activity the MD rejects as it should by the challenged verification methods, how is this a deviation at this CCP?

A metal detector reject is not a deviation of a CCP. The metal detector functioned exactly how it is supposed to.
The only thing to do is investigate the FM source.

I suppose there is (somehow) a "deviation" of the validation of CCP if it continually, wrongly, rejects.

99.9% false positives ???
This is really terrible! This must be improved. I think such high false positives have actually caused MD to lose its meaning and greatly increase the intensity of your meaningless work.
Because in this case, MD itself will lose everyone's trust! Among our customers, this is absolutely intolerable and must be improved.
We are a service provider of equipment, which may be due to the following reasons:
1, Because you mentioned moisture and frozen, I guess the most likely reason is that your product is not sufficiently deep-frozen.
May I know what food you produce?
2, If deep freezing is not possible for any reason, the MD detection standard you set is actually not reasonable.
In other words, your MD cannot reach the current detection capability in this case.
3, There may also be reasons for the equipment itself, such as no professional maintenance.
This is actually very complicated, not to mention here.
4, As service providers or users, we should evaluate false positives.
If you can provide data of 200 or more signal values for your product, Fe, NFe and SS respectively, totaling 800 datas and the more the better, I can analyze it for you here!
Under normal circumstances, we help users achieve about one-thousandth of false positives.
This is our analysis method:

I don’t know if I have described this issue accurately, if anyone has further questions, I would be happy to discuss with you.
Many thanks.

I'm sorry, very sorry. I sincerely apologize for any offense or rudeness!
Since English is not my native language, I may not be able to describe my apology most accurately, including previous responses.
But anything that makes you uncomfortable, I'm really very sorry.
And it’s almost impossible for me to conduct any meaningful business here, because we are not in the same country.
But I do want to share my experience with everyone.
And in fact, almost all of my experience has benefited from my customers, who are almost all multinational factories from your country.
I am really grateful to these high-quality customers. It is precisely because of their extremely high quality control standards that they reversely promote my further thinking and improvement.
So I should also thank you and the excellent companies in your country!
Any offense, my sincere apology again! I'm very very sorry!
