The Dáil has heard that some meat processing plants were inspected this week by the Health and Safety Authority and a high level of compliance was found.
Minister for Business Heather Humphreys said the authority conducted over 240 onsite compliance workplace inspections between Monday and yesterday and these include meat processing plants.
She said a high level of compliance had been found.
Ms Humphreys said the clusters in the plants were first and foremost a public health issue.
Minister for Agriculture Michael Creed said the situation was constantly evolving and he would not agree that mistakes were made.
The two ministers are taking questions from the opposition on outbreaks of Covid-19 in meat plants.
Fianna Fáil agriculture spokesman Charlie McConalogue said it was disappointing that the Minister for Health, Simon Harris, was not taking questions as had been planned.
Mr Creed said the Mr Harris addressed the outbreaks during questions on health matters in the Dáil h earlier today.
Several opposition TDs have called for factories to be deep cleaned when cases are confirmed.
Mr Creed said this would be decided by the outbreak control team.
Sinn Féin Agriculture spokesman Brian Stanley said that assurances that all was OK in meat processing plants was "a load of bull".
The Laois/Offaly TD said those promising that everything was OK must be wearing blindfolds.
He also pressed Minister Humphreys to disclose the exact number of HSA inspections in meat plants.
In response Ms Humphreys insisted the information is confidential and the authority does not tell her.
Sinn Féin TD Claire Kerrane said it was very concerning that inspections only began this week as some cases of Covid-19 were detected in meat plants in April.
