Using NACMCF Parameters for Challenge Study Protocols for Retail Food Operators and Regulators

These documents provide guidance for how to design, review and approve challenge studies per the National Advisory Committee on Microbiological Criteria for Foods. These documents can be used by both the food establishment operator when they need to submit a challenge study for review, as well as state and local health officials when reviewing and approving the documents. Along with the guidance document, there is a checklist and a worksheet to assist in design, review and approval.
