These MLVA types of S. Typhimurium were also isolated from free-range farms sampled in this study. Three MLVA types (03 14 10 12 523, 03 14 11 12 523, and 03 12 09 10 523) were not isolated from human cases in 2013 or 2014. However, these MLVA types started to appear in humans in 2015. This underlines the connection between the free-range layer industry and the potential threat of Salmonella to public health. Data are from quarterly reports of the Australian Salmonella Reference Centre (2013, 2014, and 2015), Institute of Medical and Veterinary Sciences, SA Pathology, Adelaide, Australia.
