The monograph contained in this volume was prepared following the ninety-third meeting of the Joint Food and Agriculture Organization of the United Nations (FAO)/World Health Organization (WHO) Expert Committee on Food Additives (JECFA), which met virtually online from 24 March–1 April 2022. This monograph summarizes the data on the contaminant group trichothecenes T-2 and HT-2 toxins reviewed by the Committee. A monograph on the other features of this contaminant group, which were discussed at a previous meeting in 2001, are published in WHO Food Additives Series 47.
