Rhodamine B usage in food coloring

Rhodamine B has been found in food samples like Gobi Manchurian and cotton candy from Karnataka. It is predominantly used in smaller cities by smaller vendors like those selling ice creams and cotton candy in non-commercial vehicles. Larger cities typically use food-grade colorings like in chicken dishes. Rhodamine B is not considered safe for consumption, and its usage is mainly due to lack of awareness among vendors. Experts have expressed concerns about the potential harm that Rhodamine B can cause in humans, including its carcinogenic properties.
