Dear kittyk,
Thks for info. I only know about icecream as a consumer but I presume must be classified as a “high” risk product.
The selection of supplier / ingredient can IMO be made qualitative, eg by listing various minimum requirements for the supplier as a function of the product risk category, eg signed agreement to specs / acceptable audit / possessing appropriate certifications such as ISO etc, etc. But not so sure if supplier performance evaluation can be done that simple. ISO 9000- type scoring systems certainly exist (I think I hv some in my archives if you are interested) but not so easy to use for HACCP safety type defects IMO. The last item will, IMEX, also require some (external ?) micro.analysis data at a minimum and possibly chemical also, (perhaps this is already legally required ??)
Maybe someone can offer a more minimalist solution.
