Exploring arcobacter risk to the food industry and human health
A research team from the University of the Basque Country has conducted a study into the prevalence and characterisation of bacteria of the Arcobacter genus using a large number of samples of different foods (seafood, vegetables, meat products and fresh cheese), including some that have never been analysed in our environment previously. In addition, they have studied the ability of these bacteria to adhere to various surfaces frequently found in food processing environments.

Several species of the Arcobacter genus are regarded as emerging food pathogens and may cause gastrointestinal disorders.

A total of 220 samples were analysed from three major food groups: farm animals, marine animals and vegetables. Arcobacter were detected in 22.3 % of the samples analysed and the most abundant species in all of them was A. butzleri, the one most often associated with human disorders, although other species also appeared, all of them had genes associated with pathogenic potential. Squids have been found to be the major source of Arcobacter.

Their results confirm the formation of biofilms caused by foodborne Arcobacter bacteria on different food contact surfaces, e.g. glass.
