An outbreak of COVID-19 cases at a meat processor in northern England owned by British supermarket Asda has caused the plant to close temporarily, the retailer says.
Asda said it had been working with public health authorities to ensure staff were tested, and that while the factory in Cleckheaton, West Yorkshire, had not been forced to shut, it had been closed as a precaution.
It did not confirm how many cases had been found.
"As soon as we became aware that some colleagues at our Kober site may have COVID-19, we responded swiftly and worked collaboratively with the local authority and Public Health England to test all colleagues," a joint statement by Asda and Kober Limited, the firm which runs the plant, said.
The closure is the latest in a series of outbreaks linked to meat processing plants across Europe and the Americas.

British trade union Unite said it had received reports of five more suspected outbreaks at different meat processing factories, without providing further details.
The union said employers had to do more to protect their staff while academic experts outlined risks of working in a factory environment.
"Factories and, in particular, indoor areas which are cold and damp are perfect environments for coronavirus to linger and spread," said Lawrence Young, Professor of Molecular Oncology at the University of Warwick.
"The virus survives on cold surfaces and, in the absence of ventilation and sunlight, virus-containing droplets from infected individuals are more likely to spread, settle and stay viable."
The death toll from confirmed cases of COVID-19 in the United Kingdom rose by 173 to 42,461, health officials said on Friday.
