Recently I have been invited to participate as an expert in the annual meeting of FAO/WHO on Microbiological Risk Assessment (JEMRA), associated with Shigatoxin-producing Escherichia coli, September 2017, Rome, Italy.
Furthermore, in 2018 I have been invited to participate as an expert in Shigatoxin producing Escherichia coli topic, for a period of five years in the FAO/WHO Microbiological Risk Assessment (JEMRA) group.
In 2018, part of our work was published and described in the FAO/WHO/JEMRA Report 31 of the meeting held in Rome. ( http://www.fao.org/documents/search/en/?jobnumber=Q0EwMDMyRU4= ), also has been added Report 32.
