Worldwide, over 80 plant species are known to cause poisoning from nitrate accumulation. But droughts are exacerbating this for many staple crops. Even after a drought, the growth in water-stressed crops can result in the build-up of other toxins. Global warming is also helping to spread mycotoxins, with 25 per cent of cereals worldwide estimated to be contaminated and 4.5 billion people exposed to uncontrolled levels. We will need an aggressive strategy to ensure the safety of agricultural yields and food in the future especially in drought- prone and even temperate zones.
