A four-hour purification ritual was carried out at the revered Sri Venkateswara temple of Tirumala in Andhra Pradesh's Tirupati district amid row over allegations of adulteration of laddus offered as 'prasadam' there. Temple sources cited in a news agency PTI report purification ritual was held to please the Lord Venkateswara Swamy after the alleged "sacrilegious practices such as mixing animal fats" in making Tirupati laddus (consecrated sweet) and others.
