Food processors who fall under the Intentional Adulteration Rule (IA Rule) must conduct a vulnerability assessment as part of their food defense plan. A vulnerability assessment measures potential public health impact (e.g. severity and scale), degree of physical access to the product, and the ability of an inside attacker to successfully adulterate your products. In this blog, we’ll look at the easiest method to conduct the vulnerability assessment – by considering key activity types. Key activity types are FDA-identified categories of food manufacturing processes that are most vulnerable to intentional adulteration.
