Public Health Minister Anutin Charnvirakul is pushing to delay the reopening of night entertainment venues.
Numerous businesses were found to have not implemented disease control measures which resulted in major outbreaks in many provinces.
Mr Anutin said it was clear that many Covid clusters were linked to bars and restaurants where alcoholic drinks were served.
He said their repeated failure to implement disease control measures has forced the government to reconsider its plan to reopen certain entertainment venues, such as nightclubs.
The minister said "the lack of conscience" has again put the country at risk of a new wave of Covid-19 infections, adding that he has asked the local communicable diseases committee to pursue legal action against businesses that violated public health guidelines.
According to the Department of Medical Science, there were a total of 2,062 Omicron cases as of Tuesday, with major clusters reported in Kalasin (231 cases), Roi Et (180), Chon Buri (70) among many others.
