With the wet and humid conditions that we have seen this year, fungal diseases and problems like mycotoxins in grain have been a big issue. Climate models predict that wetter and more humid conditions are going to become more frequent in the future, and we are already seeing a trend in that direction, although 2020 is a wetter than usual year due to all the tropical activity we have seen and not just climate trends. This article from The Counter describes how molds produce mycotoxins when they are stressed by weather like high temperatures. It also describes the effects of these mycotoxins on livestock.
