*TSE, transmissible spongiform encephalopathy; MPL, minimum prevalence level (upper limit of the percentage of positives in the population, given no positives found in the sample); HB, hunting bag (cervids >18 months estimated for the 3 study years); EPS, estimated population size (cervids >18 months in the 3 study years).
†Animals were considered at increased risk if >1 risk factor applied.
‡Animals were considered at normal risk if no risk factors applied.
§Data analysis was possible for 6,440 animals; information on risk factors was lacking in 616 cases.
