Abbreviations: ADIS, Animal Disease Information System; ECDC, European Centre for Disease Prevention and Control; EFSA, European Food Safety Authority; ELISA, enzyme‐linked immunosorbent assay; MSs, Member States; PCR, polymerase chain reaction.

^a Data from the United Kingdom are taken into account for 2017–2019, because the United Kingdom was an EU MS, but it became a third country on 1 February 2020.

^b One case reported from the EU was later found to have originated in Mayotte.

^c Samples tested using an unspecified analytical method are not included.

^d PCR: polymerase chain reaction.
