A recent study by the Russian department of consumer rights, Roskachestvo, has found that a brand of sour cream from the Moscow region, marketed as high-end, is a fake with the use of vegetable fats instead of natural ingredients. The study also found that 17% of the sour cream samples failed safety tests, with Escherichia coli bacteria found in some, indicating sanitation issues in production. Additionally, 26% of the samples had issues with taste, smell, and consistency, suggesting low quality raw materials.
