The reopening of the Carroll Cuisine meat processing plant in Tullamore, Co. Offaly has been approved by the HSE and Health and Safety Authority.
Both have reviewed and approved the extensive measures Carroll Cuisine have put in place to prevent the spread of Coronavirus.
Nine employees at the facility had tested positive for the disease.
This led to operations at the facility being suspended as the processor awaited the results of testing on hundreds of other staff members.
210 out of its 330 staff were tested over the weekend.
All of those results came back negative.
In a statement, Carroll Cuisine says "The tests provide confidence that the actions we’re taking are effective. Taking into account the approval we have received, and the rigorous prevention measures we have in place, we will begin carefully and gradually resuming operations on a phased basis over the coming week."
