One of Britain's biggest food companies, 2 Sisters Food Group, has suspended production at a poultry processing plant in North Wales for 14 days after a COVID-19 outbreak.
2 Sisters Food Group, which produces around a third of all poultry products consumed in the UK, said it would transfer production to the company's other plants until 2 July.
It said a first member of staff at the plant at Llangefni on the Isle of Anglesey tested positive for COVID-19 on 28 May.
Public health Wales said in a statement that there had now been 58 confirmed cases at the plant and all employees and contractors had been asked to self-isolate for 14 days.
The plant employs 560 people.
There have been a series of COVID-19 outbreaks at meat processing plants across Europe and the Americas.
An outbreak at an abattoir in northern Germany prompted one of Germany's largest meat processors, Tönnies, to stop slaughtering.
