Around 1,000 people have been placed in quarantine after a mass coronavirus outbreak at an ice cream factory in the German city of Osnabrueck.
The people in isolation were employees at the factory and their relatives, a city spokesperson said.
People who tested negative in a first test on Tuesday are to be tested again, the spokesperson said.
Until now, 210 people have tested positive in connection with the outbreak, of which three are said to have caught the more contagious B117 variant that was first identified in Britain.
Production at the factory has been suspended until at least February 26.
