We shred a case of block cheese using our Hobart with a shredding wheel directly into our bus buckets - 4 loaves to a bin, with a lid. I found if we put a baking parchment sheet on the top before the lid goes on, if any moisture condenses on the top, the parchment keeps it from dripping back in. We use it up within 4 days, but there are some times we are away up to 5 or even 6 days. The only time we had any problems was in a replacement cooler where we keep the dough next to our dough table, the cheese bins were kept in the bottom, it just seemed to not hold cold enough and it tended to spoil within 3 days. We moved the bins to a different (better regulated cooler) and we’ve not had an problem since. Check your storage temp.
