Hi Kelly,
The FDA guidance is here:
FDA's "Adulteration Involving Hard or Sharp Foreign Objects"Their range is 7mm - 25mm. The thing is, try arguing this with a customer or auditor. You have to determine what the maximum acceptable size of
metal contamination allowed based on risk analyses at each step in you process flow (should be done not just by yourself, but a cross functional
HACCP team). There are a lot of variables involved; what's your product, wat's your process flow; how do you control metal (metal detectors, screens/seives, rare earth magnets?), is it a Control Point or
Critical Control Point, etc?
Regarding your question about determining corrective action/product disposition after finding a piece of metal after running 30K bottles; assuming it exceeds your critical limit set in your
HACCP plan (if the step is a
CCP), the action you would take would be dependant on the last time you ran a
CCP check and whether or not your
CCP is capable of detecting the size of the piece you found
If you find metal in your product that's "very tiny like a grain of sand" I'd have to say that if it's over your maximum critical limit set in your
HACCP plan you're going to have trouble. What corrective action was taken? Was questionable product put on hold and was a disposition decision made? If so, by whom? Based on what facts?
If it's below you critical limits how would you even find it (and a peice of metal the size of a grain of sand might get caught by a fine mesh screen, but not likely by a
metal detector)? Again, if it's above your set Critical Limit, the response would be the same as the example above.
HACCP is not an easy subject!
Good Luck,
