Investigations Operations Manual

2024 Investigations Operations Manual (IOM)

The Investigations Operations Manual (IOM) is the primary operational reference for FDA investigators and other field employees to perform investigational activities in support of the agency's public health mission. Although primarily used internally by FDA staff, it is available publicly so that regulated industry and other external stakeholders can better understand FDA operations.
