According to Article 12 of Regulation (EC) No 396/2005, the European Food Safety Authority (EFSA) has reviewed the Maximum Residue Levels (MRLs) currently established at European level for the pesticide active substance ethoxyquin. Although this active substance is no longer authorised within the European Union, an MRL was established by the Codex Alimentarius Commission (CXL). Based on the assessment of the available data, EFSA assessed the CXL, and a consumer risk assessment was carried out. The CXL was found not to be adequately supported by data and a possible risk to consumers was identified. Hence, further consideration by risk managers is needed.
