Gastrointestinal Parasites of the Domestic Pig (Sus scrofa) in Enugu State, South East Nigeria

This study investigates the prevalence and intensity of gastrointestinal parasites in domestic pigs in Enugu State, located in Nigeria's South East geopolitical zone. Pork is an economically important protein source in the South East zone, and helminthiasis in pigs poses both production and public health risks, particularly through Taenia solium and Trichinella infections. Gastrointestinal tracts were collected from 200 pigs at two abattoirs in Enugu and Agbani over five months. Each tract was examined by total worm count after washing contents through standard sieves. Worms were identified morphologically. Data on pig age, sex, weight, and rearing system were recorded. Overall helminth prevalence was 71.5 percent. Six helminth species were identified comprising four nematode species and two cestode species. Ascaris suum was the most prevalent (54%), followed by Oesophagostomum dentatum (38%) and Hyostrongylus rubidus (26%). Taenia solium cysticerci were found in the musculature of 4.5 percent of examined carcasses, representing a significant public health hazard. Higher prevalences were recorded in free-range pigs compared to confined animals. Younger pigs (under six months) had significantly higher infection intensities. The study underscores the need for meat inspection strengthening at Enugu abattoirs, mandatory anthelmintic treatment programmes, and public health education campaigns about the zoonotic risks of Taenia solium in pork.
