Hyderabad: The special task forces formed by the state government's food safety department to monitor the rampant practice of food adulteration in the state, since September, sent notices to 20 eateries who were violating FSSAI norms, adversely impacting public health. In the latest case, officials inspected a food manufacturing centre in the Manoharabad area of Medak and found chips and other Namkeens (snacks) being manufactured with expired spices. While conducting checks in the past 90 days, officials observed several manufacturers obtaining licenses under one name and then selling products to retailers under some other famous brand.
