One more staff member has tested postive for the coronavirus at the Wensleydale Creamery, bosses say.
The Hawes company confirmed on Tuesday that five staff had the virus.
There have since been one further positive tests, the creamery said on Saturday.
The employees with the virus all work in the production area at the site in Gayle Lane.
All production staff have been tested for Covid-19.
Several members of staff are isolating as a result of their colleagues’ positive tests.
There have been no confirmed cases in the visitor centre, which remains fully open, the company says.
