Following activist Shiv Shankar Gupta’s claims of alarmingly high levels of potassium ferrocyanide in top Indian brands including Tata Salt, the company has assured in a recent statement that its product is safe for consumption. They also claimed that the level is within permissible limits. Found as E536 on the ingredient label, Potassium ferrocyanide is often used as an anti-cakeing agent. India is one of the few countries along with US, Europe, New Zealand and Australia that has allowed its use, but some countries have banned it. The level permitted by regulator FSSAI is 10 mg/kg, but the Codex Alimentarius, an authoritative guideline on food safety, has declared potassium ferrocyanide as safe for consumption at levels of 14 mg/kg.
