Affected population The affected bovine, a Salers female born on April, 8th 2011, showed paresis and was euthanized on March, 1st 2016. Samples made on March, 4th 2016 during rendering were analyzed at the Department Laboratory of La Somme. The rapid test proved positive on March, 8th 2016 and the samples were then sent for further analysis to the National Reference Laboratory, ANSES, which confirmed a case of classical BSE on March, 21st 2016. The European Union Reference Laboratory confirmed those results on the basis of documentation on March, 23rd 2016.

  • Unknown or inconclusive
Epidemiological comments The last case of classical BSE was detected in 2011. The case detected in 2014 was atypical BSE. A by-law declaring infection was issued and prohibited any movements until sanitation. A traceability investigation is on-going to identify animals potentially at risk (cohort and offspring) that will be destroyed. An epidemiological investigation aimed at identifying the potential causes of infection was launched. The requirements applicable to the category of countries with a controlled BSE risk (SRM list) enter into force as of the date of March, 25th.
