Dear Erodart,
According to the standard that you are working for and When you do your food safety plan (HACCP, HARPC or any other plans) you shall mention your refrences that helped you to design these plans, in your inquiry CGMP according to FDA website "The CGMP regulations for drugs contain minimum requirements for the methods, facilities, and controls used in manufacturing, processing, and packing of a drug product." this means that you can put more programs to make your product and facility safe.
When you put it as a refrence, you can add it as a hyperlink, the person who want to check will take him/her to the site and read what is this regulation about.
Hope tht i could help you!
