Nearly 100 workers at two north Wales food processing factories have tested positive for coronavirus.

Public Health Wales has confirmed 58 cases at the 2 Sisters chicken factory in Llangefni on Anglesey, with all staff now being told to self-isolate.

In Wrexham, 38 staff have tested positive at Rowan Foods, which makes food for supermarkets across the UK.

2 Sisters has suspended production and closed the Anglesey chicken factory, which supplies local authorities, hospitals, restaurants and small businesses.

Public Health Wales (PHW) said staff and contractors working at the processing plant, which has 560 workers, had been asked to self-isolate for 14 days.

It said staff at the factory would be tested, with all workers being contacted by the company to arrange the tests.
