EU reduces MRLs for metazachlor on radishes, broccoli, cauliflowers, kales and swine liver
Commission Regulation (EU) 2023/377 of 15 February 2023 amending Annexes II, III, IV and V to Regulation (EC) No 396/2005 of the European Parliament and of the Council as regards maximum residue levels for benzalkonium chloride (BAC), chlorpropham, didecyldimethylammonium chloride (DDAC), flutriafol, metazachlor, nicotine, profenofos, quizalofop-P, sodium aluminium silicate, thiabendazole and triadimenol in or on certain products
Update
The European Commission has lowered the MRLs for metazachlor on radishes, broccoli, cauliflowers, kales and swine liver.
Impacted Products
radishes, broccoli, cauliflowers, kales, swine liver
What is changing?
The MRLs for metazachlor have been decreased as listed in Table 1.
Why?
New data relating to certain products has enabled the metazachlor MRL for kales and swine liver to be set (EFSA 2019). On the basis of this data, existing MRLs for radishes, broccoli and cauliflowers have been reduced to the limit of determination.
Timeline
The new MRLs for metazachlor will apply from 14 September 2023.
Recommended Actions
Suppliers of radishes, broccoli and cauliflowers currently using metazachlor should seek alternative solutions.
Suppliers of kales and swine liver should evaluate current metazachlor residues to assess whether changes are needed to existing good agricultural practices (GAP) in order to ensure compliance with the new MRLs by September 2023.
Background
MRLs are set in accordance with the rules set out in Regulation 396/2005. For information on current MRLs for other substances, please consult the EU Pesticide Residues database.
