Abstract The objective of the present study was to determine the prevalence of fasciolosis and hydatidosis in slaughtered domestic ruminants based on records from different communal abattoirs in Bejaia province. All daily records for cattle, sheep and goats were used in the current investigation. Each animal carcass was inspected at least by one veterinarian. The data were collected from January 2009 to December 2016. The prevalences of fasciolosis (2.83%) and hydatidosis (2.49%) in cattle were significantly higher than in sheep (0.13% and 2.24%, respectively) and goats (0.12% and 1.82%, respectively) (P ≤ 0.05). In cattle, fasciolosis peaked in January, and then gradually decreased from March to September, while in sheep and goats fasciolosis was present at constant rates all around the year (Fig. 3). Regarding the rate of hydatidosis, the monthly prevalence did not vary significantly in cattle, sheep and goats except in October, when a high rate was recorded in cattle. In conclusion, the findings of the present abattoir study have provided baseline data for monitoring of domestic ruminant fasciolosis and hydatidosis in Bejaia province. However, we suggest that these parasitic diseases should be investigated further at the farms in order to determine the risk factors such as animal ages and breeds, and develop economic strategies for disease control at the farms. Key words: fasciolosis, hydatidosis, abattoirs, Bejaia province
