TSE (transmissible spongiform encephalopathy) has been found in a moose or European elk (Alces alces) for the first time ever in Finland. The disease was diagnosed in Kuhmo in a 15-year old moose that had died naturally. The results of the analyses carried out by Finnish Food Safety Authority Evira have been verified by a EU reference laboratory. Species of the deer family, known as “cervids”, can suffer from TSE, and it is always fatal. The disease is not known to have been contracted by people.

Norway was before this case the only European country where TSE has been diagnosed. The monitoring of the occurrence of the disease was intensified from the beginning of 2018 in Finland and five other EU Member States.

In Finland, the occurrence of the disease has been studied already since 2003. None of the ca. 2 500 samples analysed so far had tested positive for the disease. The monitoring of the disease will now be further intensified in the Kuhmo and Kainuu region. Hunters are going to be provided with more instructions before the start of the next hunting season, if appropriate.

Cervid TSE is not known to have been contracted by people. Moose meat is safe to eat and no restrictions are imposed on the sales and exportation of meat of animals of the deer family. As a precautionary measure the export of live animals of the deer family to other countries will be discontinued for now.

Cervid TSE is a slowly progressing disease of deer, elk, reindeer, and moose which always leads to death. Cervid TSE is a prion disease and related to the BSE (bovine spongiform encephalopathy) and other TSE diseases (transmissible spongiform encephalopathy).The moose found in Kuhmo did not suffer from the North American, transmissible form of the chronic wasting disease (CWD), but from the form diagnosed in Norway, which is found incidentally in individual animals of the deer family.

Updated 27.5.2020: The name of the disease has been changed from CWD to a TSE in a moose based on a recommendation from  the opinion of the EU reference laboratory in 2018 not to use the term CWD for the TSE-case found in a moose in Finland.
