The Enforcement, Investigations, and Analysis Officer (EIAO) Comprehensive Food Safety Assessment Methodology (FSIS Directive 5100.1) provides instructions to EIAOs on how to conduct FSAs using a new work methodology, so an EIAO can complete the in-plant portion of most FSAs in 5 to 7 production days. This directive also provides instructions on how to document FSAs using the FSA tools that are a series of questionnaires that an EIAO is to use to gather information. The new work methodology is designed to focus the FSAs on public health risk and to increase consistency in how EIAOs conduct FSAs.
