Bovine cysticercosis and taeniosis: The effect of an alternative post-mortem detection method on prevalence and economic impact

Publication date: Available online 12 October 2018Source: Preventive Veterinary MedicineAuthor(s): Famke Jansen, Pierre Dorny, Dirk Berkvens, Sarah GabriëlAbstractIn Europe, bovine cysticercosis (BCC) is detected by routine meat inspection (MI) at the slaughterhouse. The prevalence of BCC in Belgium based on MI is estimated at 0.23%. MI has a known low sensitivity for animals with localised infections and alternative detection techniques should be considered.A mathematical scenario-analysis model was built to determine the current prevalence of BCC in Belgium based on MI results combined with results of dissection of the predilection sites (PS) and the B158/B60 Ag-ELISA on serum of 614 carcasses found negative on MI. Additionally, the impact of the introduction of the B158/B60 Ag-ELISA at slaughter on the prevalence of BCC and taeniosis and on the economic impact related to Taenia saginata was estimated for Belgium. Data for estimating the economic impact where gathered from multiple sources within the meat and human health sectors and included value loss for infected carcasses, inspection costs, carcass destruction costs. cattle insurance costs and costs related to taeniosis (consultation physician, drugs and laboratory test).The model estimated the current prevalence of BCC to be 42.5% (95% CI: 32.4 - 60.7%) and the sensitivity of the MI for viable and degenerated cysticerci at only 0.54% (95% CI: 0.37 - 0.71%). A total of 213,344 viable cysticerci (95% CI: 122,962 - 386.2...
