Abstract
Trichinellosis is a worldwide zoonosis with genotypes affecting different domestic and wild animals and is widely distributed
throughout the world. Species and genotypes of this genus affecting different animals have been identified. Despite its occurrence
in Sub-Saharan countries, the presence of trichinellosis in Botswana is yet to be confirmed. The objective of this study was to
determine the prevalence of Trichinella infection in domestic pigs slaughtered at an abattoir in Gaborone, Botswana. Of the 111
pig carcasses selected, 5 g of crus of the diaphragmwas collected from each carcass, trimmed of all fat and fascia and then cut into
1- to 2-g samples. Themuscle samples were pooled into 100-g muscle sample and then processed by the OIE prescribed digestion
method. A stereomicroscope was used to examine each grid of the Petri dish for the presence of Trichinella larvae. No Trichinella
larvae were found in any digested muscle samples. Future studies should target a wider pig population and other host animals.
