The zoonotic parasite, Taenia solium, is a serious public health threat in countries where it is endemic. The larval stage of this parasite is responsible for porcine cysticercosis and neurocysticercosis in humans, which is one of the leading causes of seizures and epilepsy in developing countries. While documented studies have only been conducted in western areas of Kenya, other areas, including Nairobi, have not been investigated to fully understand the epidemiology of the parasite. Seven hundred blood samples were collected from randomly selected pigs presented for slaughter at the largest porcine abattoir supplying unprocessed pork to butcheries within Nairobi city and its surroundings. The samples were tested using an antigen ELISA to determine the prevalence of cysticercosis. Information regarding the pigs’ age, sex and source was obtained from the traders and pork destinations recorded.
