| 2022 | The present Meeting continued the evaluation of omethoate on the basis of data provided in 2019, new data on the genotoxicity of omethoate and new data on other metabolites of dimethoate. The ADI and ARfD for omethoate are 2.5-fold and 10-fold respectively lower than those established for dimethoate in 2019. |

| 2021 | Some data were submitted for metabolites, however the sponsor indicated that although further new studies had been performed, the results were still not ready for submission. No further information from the above studies on metabolites of dimethoate were received in time for the September 2021 meeting. In view of the above, and in the absence of complete study results, the Meeting re-affirmed the decision of the 2019 JMPR regarding the metabolites of dimethoate including omethoate. |
