Assessment of enteric helminth parasites in bushmeat in Ghana.

Anthropogenic activities, such as hunting wild animals for food, increase the risk of zoonotic transmission of infective stages of parasites to humans. The handling, processing and consumption of wild animal meat, popularly known as 'bushmeat', as well as exposure to wildlife habitats, can pose a significant risk to human health through the transfer of parasitic infective stages. This study sought to assess the enteric helminth parasite burden and potentially zoonotic helminths in fresh, wild animal carcasses being processed for food. Parasitological analysis of samples of rectal and intestinal contents collected from a total of fifty (50) wild animal carcasses belonging to eight (8) different species at the Atwemonom Bushmeat Market in Kumasi showed nine (9) genera of enteric helminth parasites with an overall prevalence of 71.0%. Individual parasite species prevalence was assessed, with sp. showing 25% and 87.5% by coprological and molecular assessment, respectively. Molecular analysis showed a higher parasite species prevalence in all samples analyzed. Species-specific analysis indicated the presence of two potentially zoonotic parasites, and , in wild animals, indicating the need to intensify one health approach in wild animal parasitic infections. Data from this study suggest that wild animals in addition to being natural hosts, may also serve as reservoirs for numerous parasites of medical and veterinary importance.
