　　This report presents the results of surveillance on transmissible spongiform encephalopathies in cattle, sheep, goats, cervids and other species, and genotyping in sheep and goats, carried out in 2023 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 (the data reported by Switzerland include those of Liechtenstein) and Türkiye. In total, 948,165 cattle were tested by EU27 and XI (3%, compared with 2022), with five atypical BSE cases reported (four H-type: two in Spain, one in France and one in Ireland; one L-type in the Netherlands); and 46,096 cattle by eight non-EU reporting countries with two atypical BSE cases reported by Switzerland. Three additional atypical BSE cases were reported by UK (1), USA (1) and Brazil (1). In total, 284,686 sheep and 102,646 goats were tested in the EU27 and XI (3.5% and 5.9%, respectively, compared to 2022). In the other non-EU reporting countries 26,047 sheep and 589 goats were tested. In sheep, 538 cases of scrapie were reported by 14 MS and XI: 462 classical scrapie (CS) by 4 MS (104 index cases (IC) with genotypes of susceptible groups in 93.4% of the cases), 76 atypical scrapie (AS) (76 IC) by 12 MS. In the other non-EU reporting countries, Iceland reported 70 cases of CS while Norway reported 7 cases of ovine AS. Ovine random genotyping was reported by six MS and genotypes of susceptible groups accounted for 6.9%. In goats, 183 cases of scrapie were reported, all from EU MS: 176 CS (47 IC) by seven MS and 7 AS (7 IC) by five MS. Three cases in Cyprus and one in Spain were reported in goats carrying heterozygous alleles at codon 146 and 222, respectively. In total, 2096 cervids were tested for chronic wasting disease by ten MS, none tested positive. Norway tested 14,224 cervids with one European moose positive.
