Assessment of Routine Inspection Method for Diagnostic of Porcine Cysticercosis in South East Benin by Using Meat Inspection Records and Ag-ELISA Test

Abstract

In South East Benin, control of porcine cysticercosis is carried out by using meat inspection. To assess routine inspection method for diagnostic of porcine cysticercosis, two studies were carried out. The study 1 was conducted by using data collected from seizures records from 2006 to 2011. The most important organ condemned was tongue (0.54%, 95% CI: 0.48-0.60) and the most important proportion of carcasses seized was 0.74%. Prevalence of porcine cysticercosis estimated with meat inspection records was 0.87% (95% CI: 0.79-0.94). The study 2 was performed on thirty-six pigs and did not revealed porcine cysticercosis by tongue examination. Nevertheless, a case of porcine cysticercosis was observed at meat inspection and 72.22% of collected sera were tested positive by Ag-ELISA (26 positive on 36). The sensitivity and the specificity of meat inspection as performed by veterinary inspectors was (0.058, 95% CI: 0.003 to 0.307) and (1.00, 95% CI: 0.791 to 0.995), respectively and no relationship was observed between meat inspection diagnostic and Ag-ELISA. This study suggests permanent training of veterinary inspector and implementation of traceability system for efficient control of porcine cysticercosis.
