A comprehensive dataset including price data and weather data affecting food safety risks was collected and used to train and test the models. Performance metrics such as accuracy, precision, and recall were used to evaluate the models. The results showed that all algorithms performed well, but the polynomial regression model achieved the best correlation coefficient for prediction models, while the decision tree achieved the highest accuracy for classification models. This research highlights the effectiveness of machine learning in predicting and classifying food safety risks and underscores the importance of leveraging advanced techniques to mitigate these risks and ensure food safety for consumers.enFood securitymachine learningfood safetyrisk predictionregressionclassificationThesis
