Epidemiological monitoring of bovine cysticercosis in France: situation in 2015

The French national meat inspection database (SI2A) was launched in all French cattle slaughterhouses on 1 January 2015. It has enabled the surveillance of annual bovine cysticercosis prevalence and incidence rates. In 2015, raw apparent prevalence was 0.123% [0.122-0.123] (95 CI) for both viable and degenerated cysts and 0.0096% [0.0095- 0.0098] for viable cysts. True prevalence was estimated 
at 1.07% [0.72-1.67] and 0.08% [0.06-0.13] for both viable and degenerated cysts and for viable cysts respectively. The comparison of raw apparent prevalence in 2010 and adjusted prevalence for age-sex in 2015 showed a slight but statistically significant decrease during this period. This decrease could be attributed either to an improvement in the bovine cysticercosis situation or to lower meat inspection  detection sensitivity in 2015 due to a difference in data collection methodologies. The implementation, in addition to the current surveillance system, of a method for identifying farms/areas at higher risk for infestation in France could enable the development of more appropriate prevention and control measures.
