I am up against the same issue - we have a warehouse that holds our products that is not audited by any outside source (they pretty much store our stuff exclusively). Our products are not considered high risk and are stored at room temperature.
As I can not expect to pull them up to SQF standards overnight I am writing an audit guideline based on basic AIB standards. I do not expect them to have all the programs in place right away - but thought I would give them an action list based on risk and return every 3-6 months until they have all in place.
I will check out the referenced sites to see if I can find any checklists - as that would be most helpful.
