The Agriculture and Horticulture Development Board (AHDB) is warning UK livestock farmers to be on the lookout for ergot and fusarium fungi in grain harvested this summer, following wetter than average weather during the 2024 growing season. Ergot is highly toxic and can cause severe health issues in humans and livestock, including seizures and death, while fusarium can reduce feed intake and damage the immune system in cattle. Farmers are advised to identify signs of these fungi and take preventive measures, although some solutions may be too late for the current harvest.
