We are a juice manufacturer and had a product transfer pump that was leaking. The seal was changed and seemed to be ok. The pump was taken a part a few weeks later and was noticed the impeller to be worn down about an inch. Now we are concerned of metal contamination and have about a weeks worth of product on hold. We have a screen in place for choking hazard <7mm >30mm along with a metal detector to detect 2.5 mm SS. The concern is infants and elderly, but I see no further sizes related to choking hazards for these. The main question I have is, if SS <2.5 mm enters into a finished product without our metal detector detecting it and are still within FDA guidelines for choking hazards, should this product be considered tainted and disposed of? We could put it through the metal detector again, but the chances of detection are slim I would think.
I greatly appreciate any and all advice!
