Prevalence and economic losses resulting from parasitic zoonosis on swine and ruminants in Ouagadougou abattoir (Burkina Faso)

Abstract

Cysticercosis and fasciolosis are zoonosis with public health and economic importance. A retrospective study was conducted with the objective to determine the prevalence and economic losses associated with meat condemnation in Ouagadougou abattoir due to two parasitic zoonosis: fasciolosis and cysticercosis. The meat inspection register was sifted through to collect data on animals slaughtered in the abattoir between 2007 and 2013. Prices of carcasses and organs have been requested from stakeholders in the meat industry. The prevalence and economic losses associated with animal fasciolosis and cysticercosis were calculated. The overall prevalence of fasciolosis and cysticercosis were 0.41% and 0.17%, respectively. The highest prevalence of fasciolosis was observed in cattle (0.82%), while the highest rate of cysticercosis was observed in pigs (0.22%). For both fasciolosis and cysticercosis, the highest number of condemnation was observed during the dry season. Total economic losses due to fasciolosis stemming from seizure of liver and carcass weight loss were estimated at XOF 142 068 284 ($258,423) while losses related to cysticercosis-infected organs and carcasses was estimated at XOF 6 286 000 ($11,434 USD). This study highlights the impact of these diseases in Burkina Faso and proves that the country’s population is facing riks of contamination.
