RSP state secretary Khisti Goswami said that a politician should guard against hurting the sentiments of a community.
"We may have our personal choices and preferences, but when you are a politician and in public life, you need to take precaution before hurting sentiments of the people of a community," Goswami said.
He, however, told PTI that Bhattacharya was learnt to have apologised to his party in the matter.
The participants included, among others, former West Bengal minister Abdur Rezzak Mollah, Bikash Ranjan Bhattacharya and writer Subodh Sarkar.
"I can eat anything in my personal life, but making that public is not a good thing when I am in public life," Goswami observed.
