Panaji: Five out of thirteen fish-laden trucks checked for formalin were sent back from the border by Goa authorities for lack of proper documentation, an official said on Sunday. The trucks were checked at Patradevi and Pollem borders in the north and south of the state late Saturday night, officials said.

"Three of five trucks at Patradevi and two out of eight trucks in Pollem were sent back because they did not have proper documentation. No formalin was found in any of the fish tested during the check," an official stated.
