At least 400 workers at a slaughterhouse in Gütersloh in western Germany have tested positive since Monday.
More employees at the Toennies plant are awaiting test results.
Germany has had nearly 9,000 deaths from Covid-19, which is significantly less than some other western European countries, including the UK, France and Italy.
But it is still dealing with localised outbreaks. Several schools and playgrounds in Magdeburg have closed, as more than 180 people have tested positive, 60 of them since Friday.
And in Berlin at least 300 households in Neukölln are in quarantine after an outbreak in a block of flats.
