Poland has not provided enough guarantees of its ability to control shipments of food products for Moscow to end its bans on imports, Russia's chief animal and plant safety officer said on Friday.

"So far, I see no evidence of improvement of the situation in the veterinary sphere. As far as phytosanitary control is concerned ... we do not have a clear vision of how they [Poland] are going to make it," Sergei Dankvert said after meeting Poland's chief vet, Krzysztof Jazdzewski.

Last November, Russia banned 15 Polish products, including flowers, grain, fruit and vegetables, meat and meat products, after finding shipments accompanied by forged safety certificates.

Some Polish politicians have interpreted the bans as politically motivated, but Russian officials have repeatedly rejected that suggestion.

Dankvert said illicit shipments of Polish meat products into Russia continued through third countries, primarily Belarus.

He said the Russian animal and plant health control service had installed a post on one of the roads that link Belarus to Russia last month and stopped some meat shipments from Poland without the necessary certificates. "It means that we have discovered a stable channel of illegal imports, and ... we told the Polish vet about it," Dankvert said.
