I have researched this issue in detail. As part of that research I watched a couple of SQF videos about the new requirements in Edition 8; these addressed both the new food fraud requirements and the other requirements.
The key takeaways are:
1) from an internal auditing perspective, all SQF facilities should start upgrading to Edition 8 now, as full compliance is expected by January 2018. And,
(2) SQF says that they are creating some training materials for the food fraud requirements but that they won't be launching anything specific until their conference in November. Which doesn't help much at all.
I totally feel your pain and am actually in the process creating some materials for SQF facilities to help understand the new requirements and create the required documents.
The free SQF webinar can be found here (as I said, it is very light on details):
Hopefully SQF will have some more information available sooner rather than later.
