Russian state news agencies say government officials have issued a total of $600,000 in fines for alleged food safety violations at Burger King and French supermarket chain Auchan.

Anna Popova, head of Russian consumer protection agency Rospotrebnadzor, was quoted by media outlets including RIA Novosti as saying Auchan’s fines totaled over 25 million rubles ($372,000) and that “several hundred” employees were suspended from work.

Specific reasons for the fines were not immediately clear and Auchan declined to comment.

Auchan is also the target of allegations from Russia’s agricultural agency, which claims some Auchan meat products tested positive for bacteria such as E. coli and Listeria. The allegations have reportedly led Auchan to close down some facilities for cleaning.

The inspections come at a time of tension between France and Russia over the extension of European Union sanctions and France’s decision to cancel a deal to provide warships to Russia.
