The European Union summary report on surveillance for the presence of transmissible spongiform encephalopathies (TSE) in 2022

This report presents the results of surveillance on transmissible spongiform encephalopathies (TSE) in cattle, sheep, goats, cervids and other species, and genotyping in sheep and goats, carried out in 2022 by 27 Member States (MS, EU27), the United Kingdom (in respect of Northern Ireland [XI]) and other eight non‐EU reporting countries: Bosnia and Herzegovina, Iceland, Montenegro, North Macedonia, Norway, Serbia, Switzerland and Türkiye. In total, 977,008 cattle were tested by EU27 and XI (−4.3%, compared with 2021), and 52,395 cattle by eight non‐EU reporting countries, with one case of H‐BSE in France. In total, 295,145 sheep and 109,074 goats were tested in the EU27 and XI (−5.2% and −7.9%, respectively, compared to 2021). In the other non‐EU reporting countries, 25,535 sheep and 633 goats were tested. In sheep, 557 cases of scrapie were reported by 17 MS and XI: 480 classical scrapie (CS) by five MS (93 index cases [IC] with genotypes of susceptible groups in 97.6% of the cases), 77 atypical scrapie (AS) (76 IC) by 14 MS and XI. In the other non‐EU reporting countries, Norway reported 16 cases of ovine AS. Ovine random genotyping was reported by eight MS and genotypes of susceptible groups accounted for 7.3%. In goats, 224 cases of scrapie were reported, all from EU MS: 216 CS (42 IC) by six MS, and 8 AS (8 IC) by four MS. In Cyprus, two cases of CS were reported in goats carrying the heterozygous DN146 allele. In total, 3202 cervids were tested for chronic wasting disease by 10 MS. One wild European moose tested positive in Finland. Norway tested 17,583 cervids with two European moose, one reindeer and one red deer positive. In total, 154 animals from four other species tested negative in Finland.
