Russia's ban on import of fresh vegetables from the European Union could be lifted, provided Europeans meet a number of conditions, head of the Russian consumer rights watchdog (Rospotrebnadzor) and country's chief medical officer Gennady Onischenko told Interfax.

"There are conditions under which Russia will again allow import of European vegetable products," Onischenko said.

"First, to establish the pathogen and causes that sparked the outbreak," he said.

"Second, to establish the transmission factor, the way in which the disease is being transmitted: which food products, water," Onischenko said.

"Third, to establish the place of origin of the contaminated products," the agency chief said.

"And the fourth condition, an objective confirmation that the situation is under control, that sick rates stopped rising," Onischenko said.

Russia banned import of fresh vegetables from the EU as of Thursday. The reason is the spread of a dangerous acute intestinal infection in Europe. Over 1,000 people have fallen ill and more than ten died in Germany.
