A mushroom plant in Golden, Co Tipperary has suspended operations after a member of its staff tested positive for Covid-19.
Walsh Mushrooms Golden said that the staff member tested positive for the virus while in self-isolation.
The company said that close contacts of the staff member were tested, which resulted in "further positive cases".
It said it is working with the HSE and all relevant authorities in contact tracing and the testing of all staff. It also said that the plant will be deep cleaned during the temporary closure.
In a statement, the company said: "As a business, we have stringent measures in place to control Covid-19 since March and we have had no incidence of Covid-19 up to this point."
A local councillor has said that a Covid-19 test centre is being erected in the village of Golden.
Speaking on RTÉ's Drivetime, Cllr Michael Fitzgerald said there are 170 people working at the mushroom facility in the village.
The Fine Gael councillor said that the development is a "worry and a wake up call" to locals about the seriousness of Covid-19.
Cllr Fitzgerald added that his biggest fear is that the county of Tipperary would find itself in the same situation as neighbours Laois and Offaly and face a localised lockdown.
