United Kingdom
the relevant metabolite is stable outside the micro-organism, see point 2.8, and
a toxic effect of the relevant metabolite is independent of the presence of the micro-organism, and
the relevant metabolite is expected to occur in the environment in concentrations considerably higher than under natural conditions.
