Methidathion is no longer an approved active substance in GB and there are no plant protection product authorisations. As harmful effects on human health cannot be excluded, it is proposed to lower all maximum residue levels (MRLs) for methidathion to the limit of quantification.  The draft reasoned opinion of the review of the MRLs for methidathion is available to view on HSE's website:  Published MRL reviews list  To meet the UKâs international trade obligations, the measures have been notified to the World Trade Organization (WTO).  View this notification  The proposed date of adoption/publication of the new MRLs will be confirmed after the WTO process and the proposed date of entry into force of the new MRLs will be 6 months after the date of adoption/publication.  On completion of this process, an update on the final MRLs agreed, along with the date of entry into force, will be communicated via HSEâs ebulletin service.  View more information and guidance on the MRL processes for GB.
