Many studies have reported the prevalence of bacterial pathogens in food products and food processing environments; however limited data is available at primary production level, such as the farm environment. Such information can be key to understanding contamination patterns through food chains. This study examined the occurrence of 9 different bacterial species across the dairy farm environment, including: Bacillus cereus, Campylobacter species, Clostridium perfringens, Cronobacter species, Shiga-toxin producing Escherichia coli, Listeria species, Salmonella species, coagulase-positive Staphylococcus species, and Yersinia enterocolitica. Seven farms were included in this study: 3 bovine; 3 caprine; and 1 ovine. Samples (n=120) taken include milk filter, milk, faeces, feed, as well as environmental samples such as soil and water. B. cereus and Clostridium perfringens were the most common among samples tested, with 41% and 38% positive among all samples tested, respectively. Cronobacter was predominantly found in feed samples, with 38% positive. Coagulase-positive Staphylococcus were isolated from 38% of milk and milk filter samples, but were not detected in any other samples taken at any farms. Salmonella species were isolated from a single farm, with serotyping identifying multiple serovars, including S. Infantis and S. Javiana. Shiga-toxin producing E. coli were identified on 3 farms, including 1 serovar O26 isolate. Of the pathogenic Listeria species, 1 sample from a bovine farm was found to contain L. monocytogenes, and L. ivanovii was detected from 4 samples, originating from 2 farms. A single bovine faecal sample contained Campylobacter species, and Y. enterocolitica was not detected on any farms. These results provide insights into the ecology of pathogenic and spoilage bacterial species in the Australian dairy farm environment.
