Bread industry uses potassium bromate and potassium iodate, substances that are banned in many countries, but not in India; Indian regulators must act immediately and ban them CSE’s new study tests bread sold in Delhi. Finds residues of potassium bromate/iodate in commonly consumed varieties. Use of potassium bromate – classified as a category 2B carcinogen (possibly carcinogenic to humans) – is banned in most countries. India still allows its use.
