Hmmm, i've never had an inspector not give a reason for something. I can see problems with maybe items that are warm being vac packed, like plastic wrapping a container with warm contents. Maybe cross contamination with raw vs. ready to eat. I pack anything from vegetables to raw chicken in my machine. On my HACCP sheet for the chicken (Sous Vide) I have a check box that says "Vac Pack Machine has been Cleaned and Sanitized". Interested in seeing what you come up with Josh
