Maximum likelihood phylogenetic tree of Salmonella Typhiurium strains based on single nucleotide polymorphisms determined from whole genome sequences. The scale represents the number of nucleotide substitutions per site. Bootstrap support values, given as a percentage of 1000 replicates, are shown on the branches. The tree shows conclusively that myonaise (marked with arrows) is the source of outbreak
