The aim of this literature review of 51 scientific papers was to answer the question - "What is the mislabelling rate in seafood products sold on the Italian market?“. Samples were considered mislabelled when the species found by DNA analysis did not correspond with the description on the label. The most sampled seafood taxa were fish (83.8%): mackerels, cods, herrings, flatfishes and jacks were the most represented species. Unprocessed fillet/slice was the most analysed retail form (61.4%), and samples were collected at retail premises (76.5%) in 10 Italian regions. The overall weighted mislabelling rate was 28.4%, with the highest levels of mislabelling reported in samples of jellyfishes, European perch, European grouper, Atlantic mackerel and samples labelled as “spinarolo”, “baccalà” or “palombo”. There were also geographical differences and type of retail channel.
