We clean and pack seed products like, sesame seeds, pumpkinseeds etc.
During our BRC last audit we have got a NC because we do not have a magnet procedure.
We have magnets in our process to protect the machines and a good extra the magnets catch the iron dust that is on the product, because of this we never paid much attention to the magnets.
The auditor noted that because we remove the iron dust from the product we use the magnets to increase the quality of the product and we need to have a magnet procedure and need to check the magnet more often and do strength tests. And he is right we need to give it more attention.
Because of this NC I am wondering the following; how hazardous is the iron dust in our product for the food safety?
We can never remove all the dust from the product, even if we let it go through 10 magnets there is still dust left on the magnets, this is also because the dust is so small that when product passes it there is a possibility that the dust comes off the magnet.
I have also included a picture of the 6th magnet in our process, as you can see there is still a lot of product on the magnets (the dust on all around the seeds so this is why even a pumpkinseed can be stuck to a magnet), this product is also cleaned with magnets at our supplier.
Are there some additional actions we need to take to remove more iron dust from the product or is this not a food safety issue?
