This report presents the results of surveillance on transmissible spongiform encephalopathies (TSE) in bovine animals, sheep, goats, cervids and other species, and genotyping in sheep, carried out in 2018 by 28 Member States (MS) according to legislation, and by Iceland, North Macedonia, Norway and Switzerland (non‐MS). In total, 1,181,934 cattle were tested by MS, a 10% decrease from 2017 and 20,402 by the four non‐MS. One case of classical bovine spongiform encephalopathy (BSE) was reported in 2018 by the UK, born after the enforcement of the total feed ban. Three atypical BSE cases (2 L‐type/1 H‐type) were reported by France. Over the year, a total of 325,386 sheep and 138,128 goats were tested in the EU, an increase of 3.4% and 17.8%, respectively, compared to 2017. In sheep, 934 cases of scrapie were reported: 821 classical (99 index cases and 97.8% with genotypes of susceptible groups) by 7 MS and 113 atypical (105 index cases) by 14 MS. Twenty‐nine ovine scrapie cases were reported by Iceland and Norway. Random genotyping was only reported by eight MS and after excluding Cyprus showed that 18.7% of the genotyped sheep carried genotypes of the susceptible groups. In goats, 523 cases of scrapie were reported: 517 classical (38 index cases) by seven MS and six atypical (all index cases) by four MS. The heterogenous enforcement of a 3‐year surveillance programme for chronic wasting disease (CWD) from 1/1/2018 in six MS (Estonia, Finland, Latvia, Lithuania, Poland and Sweden) resulted in the testing of 5,110 cervids and the confirmation of the first case of CWD in the EU: a wild moose in Finland. Other six MS tested 3,075 cervids with no positive results. Norway tested 33,037 cervids in 2018, resulting in seven new cases: six reindeer and one moose. In total, 105 animals from three other species were tested by two MS, with negative results.
