Harmonization of EHEDG guidelines and 3-A standards

Aiming to enhance food safety by promoting hygiene in the production and processing of food, EHEDG and the U.S. American 3-A Sanitary Standards organization have many common goals and a similar mission. Both organizations exchange their draft guidelines and standards for expert review and comments before publication. The EHEDG Glossary was developed in co-operation with 3-A and can be downloaded from the Free Documents section.
Matrix: The contents of all EHEDG guidelines have been cross-referenced with those of 3-A Standards Inc. and are summarized in a matrix available for download.

Download the EHEDG presentation held at the 3-A Annual Meeting 2016.

NOTE: Reproduction or further distribution of EHEDG guidelines is strictly prohibited! All documents downloaded or purchased are intended to be exclusively used by the EHEDG Member or the guideline customer.
