Proposed Future GB maximum residue levels (MRLs) amendment

Indoxacarb is no longer an approved active substance in GB and there are no PPP authorisations.

HSE has reviewed the MRLs and identified a number of MRLs which do not result in consumer exposures exceeding the toxicological reference values and therefore harmful effects on human health are not expected.

It is proposed that these MRLs are retained in the GB MRL Statutory Register. The full range of commodities for which this applies is detailed in the draft reasoned opinion.

For a number of these retained MRLs, HSE has identified that there is missing data, supplementary information to support the continued validity of the affected MRLs should be provided within 5 years of the date of enforcement of the new MRLs.

If no data is provided to support the MRL or an alternative MRL, the MRL will be lowered to the commodity specific LOQ.

The remaining MRLs are proposed to be lowered to the limit of quantification.

View the draft reasoned opinion on HSE's website.

The proposed date of adoption and publication of the new MRLs is 25 July 2026 and the proposed date of entry into force of the new MRLs will be 6 months after the date of adoption and publication.

To meet the UK’s international trade obligations, the measures have been notified to the World Trade Organization.

On completion of this process, an update on the final MRLs agreed, along with the date of entry into force, will be communicated via HSE’s ebulletin service.
