It is thought that this way, Russia is carrying out a threat the country made to the US last month, for blocking its membership in the World Trade Organization (WTO).
Russia announced it would impose import barriers on US meat, if by October the country still be refusing to admit Russia’s to the global trade group.
For over ten years, Russia has been trying to join the WTO. Only the US is still blocking the entry, seeking more concessions on agriculture.
The ban comes days after Premium Standard agreed to be acquired by Smithfield, the world’s largest pork processor.
The Russian veterinary watchdog also said that poultry imports from three US factories based in Georgia and Indiana would also be limited, from the end of September onwards.
