| contents | Determinants of Ascaridoid Nematode Infection and Anisakis-Related Zoonotic Exposure Risk in Eastern Mediterranean Gadiformes Fishes. Occhibove, Flavia López-Verdejo, Alejandro Mazzella, Valerio Cusano, Luigi Maria Palomba, Marialetizia Aco-Alburqueque, Renato Mattiucci, Simonetta Núñez-Pons, Laura Santoro, Mario Animals Gadiformes Zoonoses Anisakis Anisakiasis Fish Diseases Mediterranean Sea Ascaridida Infections Ascaridoidea Larvae of ascaridoid nematodes, particularly spp., are common parasites of commercially important marine fishes and may represent a zoonotic hazard following ingestion of raw or undercooked seafood. We investigated the ascaridoid fauna of the sympatric European hake () and greater forkbeard () from the Ionian Sea (Eastern Mediterranean), integrating host biometric and seasonal drivers with molecular identification and quantitative risk assessment (QRA) for the zoonotic . was the dominant species in both hosts, followed by ; other detected taxa included , , , and . In both hosts, the larval abundance exhibited marked seasonal peaks in summer and correlated more strongly with host liver and gonad condition indices, suggesting that seasonality, togheter with host physiological state, rather than size alone, modulates infection levels. Most larvae were found in the visceral non edible parts of the fish, while only a small proportion of these were detected in skeletal muscles (2.6% in hake and 0.6% in forkbeard), primarily in the anterior ventral fillet portion. QRA indicated a low per-meal probability of anisakiasis from untreated hake (~1 case per 52,609 meals). These findings highlight species-specific, trophically mediated infection patterns and reinforce that European hake and greater forkbeard represent minor but nonnegligible sources of zoonotic risk. Preventive measures, including immediate evisceration, proper freezing or cooking, and selective fillet trimming, are recommended to minimize human exposure. |
