Inspections, Compliance, Enforcement, and Criminal Investigations

Foreword 2014

The Investigations Operations Manual (IOM) is the primary source regarding Agency policy and procedures for field investigators and inspectors. This extends to all individuals who perform field investigational activities in support of the Agency's public health mission. Accordingly, it directs the conduct of all fundamental field investigational activities. Adherence to this manual is paramount to assure quality, consistency, and efficiency in field operations. The specific information in this manual is supplemented, not superseded, by other manuals and field guidance documents. Recognizing that this manual may not cover all situations or variables arising from field operations, any significant departures from IOM established procedures should have the concurrence of district management.

For 2014, the IOM contains some important changes which clarify or present new information and procedures. Of particular note Subchapter 8.3 - Investigation of Foodborne Outbreaks includes Farm Investigations, Approach, Sampling, Form 3623 Farm Investigation Questionnaire, Recording 483 Observations, and Reporting. As with each new edition of the IOM, please take time to review sections of the manual for changes which may apply to your work. Additions to the IOM are highlighted in gray.

Since December 1996, the IOM has been posted on ORA's Internet Website, The entire IOM is available there, with all graphics included. Future updates to the IOM will be performed periodically during the year to the on-line version. The hard copy is published annually. Remember, whether reviewing the "hard copy" or the "on-line' version of the IOM, the most recent version is the document of record.

We are committed to the continual improvement of the quality and usefulness of the IOM. Suggestions for the 2015 edition of the IOM or recommended changes, deletions, additions to the IOM may be sent to the Office of Operations, 12420 Parklawn Drive, Rockville, MD 20857 or via e-mail to IOM@FDA.HHS.GOV. If you are recommending a change or revision, please use the IOM Change Request Form available from the FDA web site.

Thank you for your continued hard work and dedication in protecting and promoting the health and well-being of the American people.
