A study by Roskachestvo has found that out of the sour cream products manufactured in 20 Russian regions and Belarus, 95% met quality standards, while 5% were counterfeit. The study also uncovered sanitary violations in five brands, including the presence of Escherichia coli bacteria and excessive yeast. The price increase of 22.3% over the year due to rising production costs has resulted in a decrease in consumption. The National Union of Milk Producers has reported a 24% decrease in sour cream imports last year.
