MOSCOW, April 30. /TASS/. Russia's agriculture watchdog, the Federal Service for Veterinary and Phytosanitary Surveillance, will limit apple supplies from Serbia, head of the service Sergey Dankvert said on Thursday.

"We have to introduce a prior notice procedure in respect of apples from Serbia. Products will not be authorized to cross the border without inspection," Dankvert said. Toughening of measures is related to a large-scale falsification of Serbian phytosanitation certificates, he added.

"The Europeans arranged a large-scale production of falsified documents for Russia. We checked 33 Serbian apple certificates and only one of them was the authentic," the head of service said.

An investigation completed by Rosselkhoznadzor showed the similar situation relatively to transit phytosanitation certificates from Bulgaria, Dankvert said. Rosselkhoznadzor had already limited the import of apples from Bulgaria, he added.
