Walsh Mushrooms in Golden, Co Tipperary, remains closed today after it emerged that 29 staff members have tested positive for Covid-19.
The company employs 170 people at its premises outside the village of Golden but after one staff member tested positive last week, further testing was carried out.
That resulted in another ten staff being told on Friday that they had Covid-19, while more tests over the weekend at a temporary facility in the village has led to, it is understood, 18 more people testing positive.
The news has caused concern in the area, but local Fine Gael Senator Garret Ahearn said it is hoped that the outbreak has been contained within the factory. "The indications are positive that it has been," he told RTÉ News.
