We trained the model by using whole-genome multilocus sequence typing data from 18,661 <em>Salmonella</em> isolates from collected single food sources and used feature selection to determine the subset of loci most influential for prediction. The overall out-of-bag accuracy of the trained model was 91%; the highest prediction accuracy was for chicken (97%).
