Attached may be help you for reference.
Thks for the DOD/NACMCF (2015) (192 Pgs!) lengthy statistical analysis/data compilation on, particularly safety-related, micro.food specs.
Includes a vast amount of cross-refs to particularly (but not exclusively) US related official documentation.
I fear the SPC and related stuff would need a batallion of employees/Statistics Dept to implement in detail but very interesting nonetheless.
Some of the compiled limits are as usual debatable but nonetheless a very useful and comprehensive category-based approach.
Recent authoritative articles on this topic seem quite rare. Thks again.
PS - One negative comment (unless i missed it) is that there seems no mention/reference to the UK/HPA micro compilation (ca 2010) for RTE foods (or its PHLS predecessors) which is/are utilised in several other National collections (eg Post4).
