The ban continues in spite of the fact that India's Federal Health Ministry has dismissed allegations that the beverages contain pesticide residues.
The sale of the soft drinks made by Indian subsidiaries of Coca-Cola and PepsiCo has been banned at schools, colleges and government offices in at least seven Indian States. One state went as far to ask the companies to shut down their plants there.
The Center for Science and Environment in New Delhi said levels of pesticides in the drinks made them unsafe for human consumption.
In an attempt to settle the issue, India's health minister told parliament that his ministry found the center's data flawed.
