Agriculture Minister Dara Calleary says his department is working on revising health protocols for meat processing plants.
SIPTU will meet with the Meat Industry later today to discuss the outbreak among workers at meat plants.
Three of four meat processing plants in the midlands are not reopening today, after recent outbreaks of Covid-19.
It's after hundreds of new cases at the facilities has led to a localised lockdown in Kildare, Laois and Offaly.
150 workers tested positive for the virus at Kildare Chilling, 86 at O'Brien Fine Foods in Timahoe and nine at the Irish Dog Food Factory in Naas.
Carroll Cuisine in Tullamore, which has reported nine cases, will re-open but is undergoing a deep-clean.
An additional 68 cases of Covid-19 nationally were confirmed yesterday with no additional deaths. None of the cases were in any county of Connaught.
Nineteen were located in Kildare, 17 in Dublin, 15 in Offaly, 12 in Laois and five in Donegal
