2)  Current activities in  Europe:  Sweden - Elements and their speciation  (Barbro Kollander,  Division of Science, National Food Agency, Sweden)

  • Ongoing activities  in Europe
    • News regarding the European  Reference Laboratory on Heavy Metals: 
      • New name  The EURL  for Metals and Nitrogenous Compounds in Feed and Food (EURL-MN) 
      • Now in Copenhagen, Denmark 
      • Hosted by Jens Sloth, Food  Institute DTU 
      • First workshop 13-15 November 
      • http://www.eurl-mn.eu/ 
    • Activities in The EURL  for Metals and Nitrogenous Compounds in Feed and Food (EURL-MN) 
      • Implement efficient methods for determination of metals and nitrogenous  compounds in feed and food.
      • Boost the communication in the EURL/National Reference Laboratories  (NRL)/ Official Laboratory network.
      •      (Each of EUs 28 countries have  NRLs)
    • Activities in The EURL  for Metals and Nitrogenous Compounds in Feed and Food (EURL-MN) Cont. 
      • Strengthen education and training
      • Address knowledge gaps
      • Ensure harmonization in analysis
      • Arrange Proficiency tests (PT) 
      • EURL-MN PT-2018-01: 
      •      Ni, Cd, Pb, Hg, As, iAs in  mixed corn poultry feed
      • EURL-MN PT-2018-02:
      •      Ni, Cd, Pb, Hg, As, iAs in  chili powder
    • NMKL. New method published: Methylmercury,  determination by isotope dilution  GC‐ICPMS in foodstuffs, NMKL method No. 202,  2018 
    • CEN. New method published: Determination of   calcium, copper, iron, magnesium, manganese, phosphorus, potassium,  sodium,  sulfur and zinc by ICP-OES, EN 16943:2017 


The second half of  the meeting discussed the future work of the group moving forward.
    

 Next we had Susan  Audino from the Cannabis working group talk   with the community about the need for a Cannabis ICPMS metals method. We  need  to ask the main working group to add for a call for methods for  Cannabis.  Laura Wood from NIST asked if Hemp could be a  possible SRM  for Cannabis. Susan agreed it would work for a metals method.
    

AOAC Official  Method 2015.01 (Heavy  metals in foods

 Next we discussed the results of the ERP that happened on Sunday  with data  from the multi-laboratory testing (MLT) of AOAC Official  Method 2015.01 (Heavy  metals in foods).  The director of the  study,  Rick Reba (Nestle) asked for members to let us know if anyone uses the method.
