The central food safety regulator has cautioned all the states to keep a hawk’s eye on edible oil, Milk, and on packaged drinking water.

In a recent meeting, the central regulator has ordered food inspectors across the nation to collect the samples of the above and send them for comprehensive testing, one of the official said.

"State food departments have been asked to be more vigilant to increase surveillance activities, especially on milk, water and edible oil. Serious violations of labeling requirements have been observed," the official said.

With the recent Maggi fiasco, several packaged food products including instant noodles, pasta, macaroni, have already come under stringent scrutiny of the FSSAI (Food Safety and Standards Authority of India) in the past one month. While the regulator banned all nine variants of Nestle's Maggi instant noodles on finding added monosodium glutamate (MSG) and excess of lead than the prescribed limit, letters were also sent to companies like Kellogg's and Heinz asks them to explain labeling etc.

Adding to the loss of Nestle, a man from Tamil Nadu's Coimbatore has alleged that he found larvae in a Nestle milk powder box from the company. He has alleged that his baby fell sick after consuming the milk.

Maggi row has thrown the Indian Consumers into a state of ambiguity.

Also recently, the UP food safety regulator had raised an alarm on allegedly finding detergent in samples of milk produced by Mother Dairy. However, the company condemned the charges saying that the company has conducted "stringent quality tests", and the complaints on the milk were part of blame game and only rumors to defame the brand.

Having dealt with enough trauma, The FSSAI has asked all food safety commissioners to "increase surveillance activities" with a special focus on these packaged products, an official source said. Putting the orders to a deaf ear will result in firm consequences, the authority warned the companies.
