Under current restrictions, pubs are not allowed to open unless they serve a substantial meal, worth at least €9, with alcohol.
Where potential breaches are identified and where a person does not come into compliance with the regulations, a file is submitted to the Director of Public Prosecutions (DPP) for a direction as to how to proceed.
A Garda statement said the vast majority of licensed premises continue to comply with regulations and licensing laws.
Deputy Commissioner John Twomey said: “An Garda Síochána continue to carry out intensive visits of licensed premises which have opened for business in accordance with Covid-19 public health regulations.
“An Garda Síochána continues to see high level of compliance, [which] is welcome and [gardaí] will continue to enforce the public health guidelines, which have now been extended until August 10 2020.”
