Apologies for digging up an old thread.
we are a company which does puddings in ceramics and unfortunately metal detector won't work for us. We are using X ray, but we don't send all products currently through it.
we have sieving as CCP with a fine mesh 1mm. Can we consider the above Canadian link as scientific evidence for the critical limit?
also, how do we check the integrity of sieve?. we check it on a daily basis in opening and closing checks.will this be enough or do we need to check it for every batch?.
also, it will be a manual visual check for the sieves. will this be enough?.
