The Karnataka government has banned the use of artificial colours in foods like Gobi Machurian and cotton candy due to health concerns over poor quality. The move follows similar bans imposed by Goa, Tamil Nadu, and Puducherry last month. Health minister Dinesh Gundu Rao cited the artificial colours as harmful and warned of serious consequences. Violations could result in imprisonment for up to seven years and a fine of up to Rs 10 lakh.
