6. Description of content:  Chlormequat is an approved active substance in G reat Britain. 
An application was received by the Health and Safety Executive to reassess the continued 
validity of the temporary MRLs (tMRLs) for chlormequat residues in cultivated fungi, 
including oyster mushrooms.  
The tMRLs were previously established to address residues that may arise in cultivated 
fungi as a result of  being grown on cereal straw lawfully treated with chlormequat. 
The latest monitoring data show that the tMRL of 0.9 mg/kg is still valid for cultivated 
fungi and the decision has been taken to re -establish this for seven years (except oyster 
mushrooms). F or oyster mushrooms the latest monitoring data supports the decision to 
raise the tMRL from 6 mg/kg to 7 mg/kg and establish this for seven years.  
The Evaluation Report and Reasoned Opinion supporting the new tMRLs is available at the 
following link. A complete list of the new tMRLs is available within this document, see 
page 5: 
The evaluation of supplementary information to support the tMRL for chlormequat in or on 
cultivated fungi  
These re -established tMRLs should be reassessed in seven years with the submission of 
monitoring data to confirm their continued validity.  
7. Objective and rationale: [X]  food safety, [  ] animal health, [  ] plant protection,

[ ] Yes   [  ] No 
If no, describe, whenever possible, how and why it deviates from the 
international stand ard: There are no Codex MRLs (CXLs) for chlormequat in or on
