There are five agriculturally important mycotoxins in food and feed, aflatoxin (1961), ochratoxin (1965), deoxynivalenol (1974), zearlanone (1966) and fumonisin (1988). In the US and Canada, contamination by mycotoxins costs the agri-food system between $200 million and $2 billion in loss each year. This accrues from testing commodities, foods and feeds, crop losses to farmers and disruptions to the value chain. In China, two mycotoxins have historically had a large impact on public health: aflatoxin and deoxnivalenol. The WHO Global Burden of Disease FERG (2015) considered all relevant chemical contaminants of food. Aflatoxin accounted for more than half the cancers (~30% of liver cancer globally) and considering the contribution of aflatoxin to child stunting, aflatoxin has a health impact equal to all chemicals found in food. Over the past three decades, very significant reductions in human exposure to these aflatoxin and deoxynivalenol have been achieved in China with the associated reductions in disease. The presence of these toxins in export commodities from China results in economic loss. In the EU, the US and Canada, aflatoxin in products sourced from China for about 1/3rd of rejections at the border.
