Gut microbiota fingerprinting as a potential tool for tracing the geographical origin of farmed mussels (Mytilus galloprovincialis).

ABSTRACT: Identifying the provenance of seafood is critical to combat commercial fraud, enforce food safety regulations and ensure consumers' confidence. Hence, the current study aimed to determine if the bacterial composition present in the digestive gland and stomach of M. galloprovincialis mussels could be used as traceability approach to discriminate their geographic origin. The microbiota of 160 mussels collected seasonally in 2019 from five different mussel farms located in three regions in Spain (Galicia, Basque Country and Catalonia) was characterized using 16S rRNA targeted amplicon sequencing. Results showed that the bacterial community composition/fingerprint was significantly different between harvesting locations and seasons, with the effect prompted by the origin exceeding the seasonal
