Coca-Cola has faced numerous controversies and allegations over its business practices in India since 1977. When the Indian government ordered Coca-Cola to reveal its secret formula that year, the company refused and left India. Upon returning in 1993, Coca-Cola took over popular Indian soft drink brands but was later accused of excessive water usage, toxic waste dumping, and selling drinks with pesticide levels above safety limits. While Coca-Cola denies wrongdoing, many Indian communities and environmental groups have continued to protest the company's operations.
