Current status of trichothecenes pollution and risk assessment in cereals and related products in China

Abstract

Wheat， corn and rice， as the main body of grain production in China， are easily contaminated by trichothecenes （TCT）. Therefore， it is necessary to investigate the pollution status of TCT and assess the exposure risk of residents from these three kinds of grains and their related products. This study reviews the published studies about TCT pollution and exposure risk assessment of residents from wheat， corn， rice and their related products in China from 2011 to 2021. It is found that most of the grains and related products were polluted by TCT， and excessive TCT content was found in some studies. From a regional point of view， the pollution in the South was more serious than that in the North. The pollution of wheat and its related products was more serious than that of corn， rice and their related products. Exposure risk assessment of residents was mainly aimed at deoxynivalenol and its derivatives. The result showed that the average exposure level of residents in most areas was within the acceptable range， but some people were at risk. In the future， the prevention and control of all kinds of TCT in grains and related products should be strengthened， as well as the exposure risk assessment of residents.
