Case Study• Nestlé has found itself in hot water in India after the local food safety

regulators said the company’s instant noodles contained unsafe levels of lead and traces of monosodium glutamate (MSG).

• The first sign of trouble emerged on 30 April when the local food safety regulator in Lucknow, the capital of the most populous state of Uttar Pradesh, demanded the company recall a batch of Maggi noodles.

• However, a disaster was brewing. Alarmed by the public anger, several states ordered tests and started issuing bans on the sale of Maggi noodles. It had became a full-blown crisis by the first week of June.

• The Sale of Maggi came to a stagnation and the Supply of Maggi was Zero• After its meeting with the national food safety regulators, Nestlé said it

was withdrawing Maggi noodles from stores “despite the product being safe”.
