Abstract
AiV-1 is considered an emerging human enteric pathogens and foodborne transmission has been documented as an important source of exposure for humans, chiefly in relation to non-safe, risky food habits. We surveyed the presence of AiV-1 in retail shellfish, including oysters and mussles, identifying the virus in 3/170 (1.8%) of the analysed samples. The AiV-1 positive samples were of different geographic origin. Upon sequence analysis of a portion of the 3CD junction region, two AiV strains identified from harvesting areas in Northern Italy were characterised as genotype B and displayed 99-100% identity at the nucleotide level to other AiV-1 strains detected in sewages in Central Italy in 2012, suggesting that such strains are stably circulating in Italian ecosystems. Interestingly, a strain identified from mussles harvested in Southern Italy could not be characterised firmly, as inferred in the Bayesian analysis and by sequence comparison, indicating that different AiV strains are also circulating in Italy. Viral contamination in retail shellfish challenges the microbiological guidelines for food control and requires the development and optimization of additional diagnostic and prevention strategies.
Conclusion
The observed increase in food-borne diseases related to the consumption of raw or lightly cooked mussels, requires continuous monitoring of common, emerging and neglected enteric viral agents, including AiV-1, in order to assess more precisely the risks for human health. In polluted environments, shellfish can play an important role as reservoirs and/or vehicles of enteric viruses. We were successful to identify AiV-1 RNA in shellfish at retail, i.e. in products at the end of the production chain and destined to direct human consumption without any further action/control by the health bodies. Monitoring of viral contamination in shellfish can be useful to gather, indirectly, information on the circulation of human enteric pathogens in local population. This will also be important to improve safety of food products and to plan more effective campaigns in consumers.
