The nutritional value of seafood products and the health benefits associated with their consumption are well known; however, they are often involved in cases of food poisoning, as potential sources of specific health hazards to consumers, arising from the marine environment in which they live.

Il valore nutrizionale dei prodotti ittici e gli effetti benefici sulla salute associati al loro consumo sono ben noti; tuttavia, sono spesso coinvolti in casi di intossicazione alimentare, in quanto potenziali portatori di pericoli specifici per la salute dei consumatori, derivanti dall’ambiente marino in cui vivono. In particolare, sono un substrato favorevole alla proliferazione microbica e attraverso la catena trofica sono in grado di accumulare e metabolizzare diversi tipi di contaminanti ambientali, tra cui le biotossine algali. Le biotossine algali sono sintetizzate da microalghe tossiche e sono responsabili di diverse sindromi da biointossicazione. I consumatori sono esposti al pericolo da biointossicazione attraverso il consumo di prodotti ittici, in particolare molluschi bivalvi, contaminati. Tale elaborato fornisce una panoramica delle principali classi di biotossine algali, con un richiamo alle sindromi da biointossicazione che queste possono scatenare nell’uomo, e un approfondimento in merito alle attività di controllo ufficiale svolte dall’Autorità Competente in conformità alla normativa europea e nazionale, con particolare riferimento alla Regione Veneto.

Abstract
The nutritional value of seafood products and the health benefits associated with their consumption are well known; however, they are often involved in cases of food poisoning, as potential sources of specific health hazards to consumers, arising from the marine environment in which they live. In particular, they are a substrate conducive to microbial proliferation and through the trophic chain are able to accumulate and metabolize different types of environmental contaminants, including algal biotoxins. Algal biotoxins are synthesized from toxic microalgae and are responsible for several biointoxication syndromes. Consumers are exposed to the danger of biointoxication through the consumption of contaminated seafood products, in particular bivalve molluscs. This paper provides an overview of the main classes of algal biotoxins, with a reference to the syndromes from biointoxication that these can trigger in humans, and a study on the official control activities carried out by the Competent Authority in accordance with European and national legislation, with particular reference to Veneto Region.File | Dimensione | Formato | |
