Russia’s consumer protection agency Rospotrebnadzor is planning to impose a ban on Sazerac’s Kentucky Gentleman Bourbon imports citing possible toxic chemical contamination.

The move comes after the agency has found traces of phthalates, organic chemicals, in the bourbon which may cause cancer and fertility problems.

Consumption of products contaminated with phthalates may also pose a threat to nervous and endocrine systems.

According to Rospotrebnadzor, the bourbon imports are also not compliant with the Customs Union technical regulations.

The agency is currently examining products from the Barton 1972 Distillery, where Kentucky Gentleman is produced.

No other bourbons from the US will be effected by the ban, The Los Angeles Times reported.

Earlier this month, Rospotrebnadzor also imposed a ban on Ukrainian juice product imports as they did not meet Customs Union technical regulations.

The moves by Russia are in response to the santions imposed on it for its support to the pro-Russian rebels in the ongoing unrest in Ukraine.
