Division 3.3.2.2 Toxicological studies
United Kingdom
These are required for fermentation products and additives not already authorised. For fermentation products, genotoxicity and subchronic toxicity studies must be provided unless:
- 1..
the active substance is separated from the crude fermentation product and is highly purified; or
- 2..
the production organism has a history of apparent safe use and there is sufficient knowledge of its biology to exclude a potential for the production of toxic metabolites.
Where the production organism belongs to a group in which some strains are known to produce toxins, their presence shall be specifically excluded.
