Based on these studies, Australia carried out a study on aflatoxin forecasting and successfully developed a model as part of the Agricultural Production Systems Simulator (APSIM) peanut module to monitor aflatoxin risks in pre-harvest peanuts using climate factors including the temperature, accumulated heat, and soil water (Chauhan et al., 2010). America established a hybrid genetic algorithm/backpropagation neural network (GA/BPN) that could predict aflatoxin contamination levels in peanuts based on environmental data.
