Hi Charles,
This link should work and bring you to a free food fraud vulnerability assessment questionnaire.
http://www.pwc.com/foodfraud
As it relates to food fraud USP's food fraud mitigation guidance is free and provides an ingredient based approach to performing a vulnerability assessment. USP also has other tools to help organizations ensure food integrity including a book of standards defining food grade for various food ingredients (food chemicals codex), reference materials, the food fraud database and training and consulting.
Economically motivated adulteration (EMA) I believe is a US FDA term as stated in the FSMA Preventive Control rule. I see the term "EMA" more analogous to the term "food fraud" which GFSI uses. I have not seen GFSI use the term EMA.
Best Regards,
Peter
