Russian officials said horsemeat has been discovered in sausages imported from Austria, the state-run news agency RIA Novosti reported.
Russia’s agriculture watchdog announced that although the sausages were labelled as 100 per cent beef "the presence of horse DNA was discovered".
The sausages are believed to have been supplied by an Austrian company, the agency added.
