Food Minister Pralhad Joshi on Friday called for an investigation into allegations made by Andhra Pradesh Chief Minister Chandrababu Naidu regarding the use of animal fat in Tirupati laddus, a claim that has sparked concern among devotees.

“Whatever the Andhra Chief Minister has said is a matter of serious concern. A detailed enquiry is required and the culprit should be punished,” Joshi told reporters on the sidelines of a global food regulators summit here.

During an NDA legislative party meeting on Wednesday, Naidu claimed that the previous Y S Jagan Mohan Reddy-led government did not even spare Sri Venkateswara Swamy temple in Tirupati and used substandard ingredients and animal fat for making laddus.
