As with many dairy companies around the world (such as Parmalat in Italy, Arla in Sweden and Express in the UK) Vivartia has been subject to accusations of collusion. In December 2007 Vivartia was initially found guilty of colluding with other milk producers (Nestlé, Fage, Mevgal and Olympos) to fix milk prices in Greece to the disadvantage of the consumer. A contested decision as milk prices are regulated by the European Union (and Greek authorities) as well as the unlawful actions of certain Greek civil servants. Management have never been charged with wrongdoing. Yet the State's Prosecuting agent investigating this case against Vivartia and Mevgal, Panayotis Adamopolous, was jailed for bribery and extortion attempts against the companies.
