Really interesting discussion and an excellent checklist.
However, I was told an interesting quote regarding food defence, though it was specifically in relation to TACCP. It related to comparisons between HACCP and TACCP.
For HACCP you need a highly developed, flexible technical mind. For TACCP you need to think like a highly developed, flexible criminal mind!
Checklists are great, but they need to be forensically questioned not taken as minimum standards.
