A _______ is a quick reference guide that lists most of the important information regarding the HACCP plan.

The concept of a summary guide in the context of HACCP provides a condensed overview of essential information related to the HACCP plan. It serves as a practical tool to quickly access key elements, such as critical control points (CCPs), monitoring procedures, corrective actions, and record-keeping requirements. This quick reference is crucial for ensuring that all personnel involved in food safety are aware of important procedures and can adhere to the HACCP plan effectively.

In contrast, while a study guide is often designed for educational purposes and might cover broader topics, it wouldn't solely focus on the specific elements of the HACCP plan. A table of contents is typically a structural component of a document, outlining what sections are included but not summarizing their details. A thesaurus, which is used for finding synonyms, does not relate to the content or specifics about HACCP plans. Therefore, the summary guide is the most appropriate choice for a quick reference that encapsulates the main points of a HACCP plan.
