The 2020 GA meeting which normally takes place in May was postponed to November 4th due to the global pandemic. The November 4th meeting which was virtual saw 20 attendees and lasted an hour as most of the GA mandated task/decisions were addressed by way of votes prior to the meeting. Chaired by Interim Chairman Dr Bernd Friede, the meeting though brief was effective with some key decisions taken as follows:
Some highlights:
- Executive Committee: A new Executive team was endorsed with the 2nd Vice-Chairman becoming the Chairman and Secretary General maintained to ensure continuity
- Non-EU letter of Access Fees: Letter of Access fees and administration fees for non-EU REACH-Like regulations per substance, per legal entity for non-MARA members was established
- Members involvement in Non-EU regulations: MARA members wishing to register substances in non-EU REACH-like regulations will only pay administration fees as they own the data generated by MARA
- Technical update: Three dossiers updated this year lead to a new classification for manganese based UVCB’s
- 2020 Workplan and budget were ratified in Q1, 2020 via round robin votes.

LOCAL LYMPH NODE ASSAY IN THE MOUSE/ MnO (Manganese Oxide)/ OECD 429/ GLP
Introduction. A study was performed to assess the skin sensitisation potential of the test material in the CBA/Ca strain mouse following topical application to the dorsal surface of the ear. The method was designed to meet the requirements of the following:
- OECD Guideline for the Testing of Chemicals No. 429 "Skin Sensitisation: Local Lymph Node Assay" (adopted 24 April 2002)
- Method B42 Skin Sensitisation (Local Lymph Node Assay) of Commission Regulation (EC) No. 440/2008
Conclusion. The test material was considered to be a non-sensitiser under the conditions of the test.
