Abstract:
Fasciolosis is a major zoonosis of ruminants which causes great economic losses to breeders. Given the economic and public health importance of this pathology, it is necessary to establish the current situation in a perspective of animal and ruminant meat consumer health protection. Therefore, the present study was conducted at the slaughterhouse of Dédougou in order to identify the species of fluke that caused this pathology in the Boucle du Mouhoun region and to estimate the prevalence, the risk factors and the economic losses associated with this pathology. For this purpose, 820 cattle and 6360 small ruminants were diagnosed through post-mortem examination over a five-month period from March to August 2018. Out of the 6360 small ruminant livers examined, no cases of infestation were observed unlike cattle in which the prevalence of infestation was 2.07%. These infestations were all due to Fasciola gigantica. Regarding the risk factors, a slight effect of the month and a high influence of animals' origin were observed. March, with a prevalence of 0.25%, was the most favorable infestation month (P-value=0.05) and Sourou (19.51%), was the highest infestation risk area (P-value<0.0001). The estimated financial loss associated with the infestations was XOF 22,200.29 per infested animal. The situation is particularly worrying insofar as some populations, especially rural populations, consume meat from uncontrolled slaughter areas. Appropriate precautions should therefore be taken to ensure both consumer and animal health, given the zoonotic nature of the disease.
