Mumbai: Ever heard of a medical iron tablet actually containing free iron particles, that too in a huge quantity? State food and drug administration commissioner Mahesh Zagde initially did not believe it. However, when a Thanebased consumer presented him with the evidence, he was left both stunned and horrified. “The consumer walked into my office, and in the presence of officials showed how the iron tablet was attracted to a magnet,’’ Zagde told TOI.
