RESUMEN
Prevalence, morphological and molecular characterization of Anisakid larvae in smoked herring fish (Clupea harengus) from five governorates that represent Northern, Middle, and Southern Egypt which include; Menofia, Alexandrina, Qaliubiya, Sohag, and Assiut were elucidated in this study, smoked herring fish samples were collected from local markets during 2020, 384 positive (42.7%) out of 815 examined samples, the highest prevalence was observed in middle and southern Egypt (Sohag (139/230, 60.43%), and Menofiya (123/215, 57.20%), they were found to be naturally infected with Anisakis simplex larvae as free in peritoneal cavity, Based on morphological, morphometric by SEM, and molecular analyses of ITS-2 ribosomal DNA targeted gene and phylogenic analysis, these nematodes were identified as third- stage larvae of Anisakis simplex.
