EFSA guidance on the assessment of microbial biomasses for use in animal nutrition

EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) has published guide lines for applicants on the preparation of dossiers related to biomasses for which a formal assessment is requested to EFSA by the European Commission, the European Parliament or a Member State. For biomasses containing, consisting of, produced from or produced with genetically modified microorganisms (GMM), this document complements the ‘Guidance document of Scientific Panel on Genetically Modified Organisms for the risk assessment of genetically modified microorganisms and their derived products intended for food and feed use’ produced by the GMO Panel’.9 For the purpose of this document the term ‘product’ refers to ‘microbial biomass’ and includes:

- The total product (cells with/without spent medium) of a microbial fermentation/cultivation process.

- The residue of a microbial fermentation/cultivation process left after the primary product(s) has(have) been removed (e.g. the residue left after enzyme or amino acid extraction).
