An anti-gay group in Russia has accused a milk vendor of promoting homosexuality to children.

The St. Petersburg chapter of the group People's Council claims Wimm-Bill-Dann's Jolly Milkman (which also translates to “gay milkman” but is not a reference to homosexuality) marketing, which includes a colorful rainbow, is in violation of a local ordinance which prohibits the “promotion of homosexuality to minors.”

“A rainbow appeared on the cartons, a world-renowned symbol of the gay movement,” said the group's Anatoly Artukh. “That immediately put me on alert.”

The group filed a complaint with city officials and prosecutors are investigating the claim, Artukh said.

Wimm-Bill-Dann is Russia's largest food and beverage company. It was purchased by PepsiCo in 2010 for $3.8 million.

“I have no doubts about Pepsi Cola,” he said. “This is a company renowned for actively and aggressively financing and promoting homosexuality.”

Artukh earlier told Reuters that the group is planning protests against the company.

“In the near future we are planning to picket the shops and hand out leaflets informing people that the money they spend on this milk will be used to finance gay propaganda,” Artyukh is quoted as saying.
