Abstract

A total of 235 frozen imported fish, 115 mackerel (Scomber scombrus) and 120 Atlantic horse mackerel (Trachurus trachurus) were collected from fish markets at Sharkia Province, Egypt, and examined for the presence of anisakid larvae. The obtained results revealed that the overall infection rate with nematodes larvae was 62.97%. The infection rate in mackerel (Scomber scombrus) and Atlantic horse mackerel (Trachurus trachurus) was 53.91 and 71.66% respectively. Four species of anisakid larvae were identified; Anisakis simplex, Phocanema decipiens, Porrocaecum decipient and Hysterothylacium aduncum with prevalence 52.76, 26.81, 9.36 and 4.25% respectively. The morphological characteristics of the recorded anisakid larvae and the best methods for prevention and control their potential risk were discussed.
