A regional branch of Russia's food regulatory agency Rospotrebnadzor claims U.S.-made whiskey Jack Daniel's contains a substance also used for insect poisoning.
The Sverdlovsk region branch of Rospotrebnadzor also said on August 22 that Jack Daniel's and Jim Beam whiskey are improperly labeled as meeting sanitary requirements and ordered regional companies to stop selling them.
Jack Daniel's has said it will challenge any accusations about its quality.
The charges come after the national food regulatory agency ordered the temporary closing at least three McDonald's restaurants in Moscow on August 21 for "numerous sanitary violations."
Pressure against U.S. products in Russia has mounted since Moscow on August 7 announced a one-year ban on most foods from the United States, the European Union, Australia, Canada, and Norway in response to Western sanctions over Ukraine.
