In Europe, one estimate is that the risk of aflatoxin contamination will increase in maize in a +2℃ temperature scenario in Europe, with nearly 40% of Europe exceeding the current legal limits . In Malawi, maize aflatoxin levels above European Union  legal thresholds are possible for most of the country by mid-21st century . The occurrence of toxin-producing fungi will increase and expand from tropical and subtropical areas into new regions and where appropriate capacity for surveillance and risk management is lacking  . The increase in toxigenic fungi in crops, and consequent contamination of staple foods with mycotoxins, will increase the risks of human and animal exposure  .
