New Delhi, May 21 (IANS): While Nestle has been asked to recall a batch of its popular snack "Maggi" after some samples reportedly tested positive for higher-than-permissible levels of lead and monosodium glutamate, in recent past some food processing companies and brands have been similarly embroiled in controversies.

The incidents were:

December 2014: In a report submitted to the Delhi High Court, the Delhi government's food safety department deemed rice dishes sold by KFC and Sagar Ratna "unsafe" due to the presence of harmful artificial colouring.

Days later, the Central Food Technological Research Institute, Mysore, reported that "cooked rice" sold by KFC "conforms" to the general provisions of food safety and standards.

June 2014: A businessman from Coimbatore found a worm in a piece of chicken bought from KFC. While the franchise restaurant refused to comment, Genesis Burson Marsteller, on behalf of KFC India, acknowledged receiving the complaint.

October 2012: Similar incident of worms being found in KFC chicken were reported from Kerala by the Food safety Department, leading to the closure of the outlet in Thiruvananthapuram.

October 2003: A few instances of worms in Cadbury dairy milk chocolate bars were reported in Maharashtra.

December 2006: Cadbury paid a compensation of Rs.15,000 to a man who found worms and fungi in his chocolate.
