EFSA is consulting on its statement on how to conduct and describe the whole genome sequence (WGS) analysis of microorganisms added to food and feed. The document provides guidance to applicants who wish to place such products on the market. The use of these microorganisms, such as bacteria, in food and feed requires authorisation, which is based on EFSA’s risk assessment. In some areas the use of WGS-based data is a requirement for risk assessment and therefore applicants need to use this new tool to prepare their applications. The deadline for submitting comments is 28 February 2020.
