Statement on the dietary risk assessment for the proposed temporary maximum residue level for chlormequat in oyster mushrooms

The European Commission requested EFSA to provide a statement in the framework of Article 43 of Regulation (EC) No 396/2005 on the dietary risk assessment for the proposed temporary maximum residue levels (MRLs) (6 and 7 mg/kg) for chlormequat in cultivated oyster mushrooms. The MRL proposals were derived by the evaluating Member State (EMS) Germany. Chlormequat residues can be found in mushrooms due to cross‐contamination from cereal straw lawfully treated with chlormequat chloride which is used as cultivation substrate. EFSA concluded that the exposure to residue levels at the proposed MRLs is unlikely to pose a risk to consumers’ health. However, EFSA recommended to take appropriate risk management actions to avoid contamination of cultivated oyster mushrooms and other fungi cultivated on straw.
