| Summary: | While a study on the presence of foodborne pathogens in in-line milk filters of Italian dairy farms authorized for production and sale of raw milk was in progress, we fortuitously detected and isolated some Arcobacter spp. during routine analysis for thermotolerant Campylobacter. This observation suggested that extraordinary and non-standardized growth conditions for detection and identification were needed to provide more information and data on this poorly known emergent zoonotic pathogen. The presence of Arcobacter butzleri and Arcobacacter cryaerophilus in milk filters of dairy farms authorized for production and sale of raw milk poses a risk for public health and rather suggests that raw milk samples should also be examined for Arcobacter contamination. While the role of Arcobacter spp. in human disease awaits further evaluation, a precautionary approach is advisable and control measures to prevent or to eliminate the hazard of Arcobacter spp. in food and from the human food chain should be encouraged as well as more epidemiological studies. With this article, we review the literature of this organism in order to focus the relevant information to food safety.
