Employees of the Tyumen customs office have prevented the import of approximately 40 tons of unknown origin and quality butter into Russia. The Rosselkhoznadzor administration has also uncovered many non-existent dairy production enterprises that have supplied hundreds of tons of domestic dairy products. The case involves a 'phantom' company, LLC "Raf", which issued fake electronic documents for large quantities of raw milk. A supply chain of counterfeit 'Krestyanskoye' butter to kindergartens and social institutions has also been uncovered, involving five Ural companies. These schemes were made possible through the use of false information in the federal state information system, 'Mercury'.
