How Animal Food Facilities Can Prepare for Regulatory Inspections

By: Marissa Herchler, Adam Fahrenholz

Though they can be a source of worry, the fact of the matter is that many animal food facilities often think about preparing for inspections as the inspectors walk through their doors. One of the reasons for this is because the "what if" questions can be large in number, and so facilities get frustrated with trying to come up with a plan. With this in mind, we asked some regulators what advice they have for facilities in order to be proactive and help make the process go more smoothly. This document presents a number of practices that are not required, but might be useful as facilities prepare for, are subjected to, and evaluate the results of inspections.
