Mycotoxins, the unknowns: trends in food availability and consumer perceptions

Food consumption habits have been changing rapidly over the last decades, and the impact of these changes on the levels of dietary exposure to mycotoxins could be relevant. In this paper, trends in availability of specific foods that are most affected by mycotoxins were analysed, and comparisons were made among different world regions. The food commodities that have been registering very high availability levels and annual increases over the last 20 years are groundnuts and nuts in Africa and Asia, and maize in Africa, which represent an important part of the diets in those regions. Other foods, which are regularly consumed only by subgroups of populations, show increasing trends in many high- or medium-income regions. Eastern Europe, Northern Europe, Australia & New Zealand, Western Africa and Eastern Asia are the regions experiencing the most dynamic changes in availability for selected foods. As individual food consumption is determined, among others, by personal risk perceptions, a literature review on the level and drivers of awareness and perception of mycotoxin risks was conducted. The scarce evidence found show a very low level of awareness and a generally moderate perception of risks derived from mycotoxin exposure, lower than risk perceptions associated with other foodborne hazards. Among the determinants of perceived risks, the education level emerges as being inversely related to the risk perception. More research is needed on these aspects, in order to better inform risk management and communication strategies related to mycotoxins.
