Présence de larves d'Anisakidae dans les rougets (Mullus barbatus) de la mer Ligure

The exposure to parasitic nematodes (Anisakidae) is usually through consumption of contaminated fish, eaten raw, undercooked, or prepared without treatment able to inactivate the larvae infectivity (eg. marinating or cold smoking). Human beings are only accidental hosts that do not allow the normal evolution of the larva. However Anisakids may affect the human health in two ways: by means of a severe intestinal immune response and by an allergic reaction to chemicals released by worms in fish flesh. The objective of our work was to assess the potential risk associated with the consumption of fish from the Ligurian Sea. The sampling was carried out in the Ligurian Sea from October 2010 to February 2013; 902 red mullets were analyzed. Nematodes of the genus Anisakis (subfamily Anisakinae) and Hysterothylacium (subfamily Raphidascarinae) were isolated. Thus, in some fish of the Mediterranean Sea, Anisakids may be a risk for the food safety.
