As of November 2019, CWA 15793 Laboratory biorisk management standard has been converted to ISO 35001: 2019 Biorisk management for laboratories and other related organizations.

This ISO standard defines a process for identifying, assessing, controlling and monitoring the risks associated with high-risk biological materials. This document applies to all laboratories or other organizations that work with, transport and / or remove hazardous biological materials. The ISO standard is intended to supplement existing international standards for laboratories.
The document is not intended for laboratories testing for the presence of microorganisms and / or toxins in food or foods. Nor is this document intended to control risks from the use of genetically modified crops in agriculture.
