I work for a coffee roasting and packaging facility, and we are SQF Level 2 Certified. When packing coffee, we hang a super sack above a ground hopper to feed the machine, and our HACCP Consultant mentioned we should find a way to cover the exposed product from settling dust during production. We will have the sack hang for about 2 or 3 hours before it empties. This is NOT something that we think poses a risk to our food, as our product is filter brewed before consumption, on top of us having NO Allergens present in the entire facility. What do you guys think? I have watched as many videos as possible of the inside of other (billion dollar) factories, all of whom have exposed product being fed into the filling machines, why was my consultant worried about our single machine in such a low risk environment?.
