Nestle India says it will destroy instant noodles worth 3.2 billion rupees ($50 million) following a sales ban imposed by Indian food safety authorities for unsafe levels of lead.

India's food safety panel says tests conducted across the country found that Nestle's Maggi noodles contained lead at levels far higher than legally allowed.

The tests also detected the chemical flavor enhancer monosodium glutamate, or MSG, which is not mentioned in the product's list of ingredients.

Nestle insists the noodles are safe and is challenging the ban in a Mumbai court.

Nestle said in a statement that the company was in the process of collecting stocks of the noodles from shops, factories and distribution centers and destroying them.
