The president of the Research Center for Independent Consumer Expertise "Test", Valentin Bezruky, has warned consumers about the risk of purchasing counterfeit food products, particularly oil and butter, through small markets and bazaars. He pointed out that supermarkets are more regulated and less likely to sell counterfeit goods. Bezruky cautioned that counterfeit products can now cost almost as much as real ones, and that consumer methods for detecting counterfeit food, available online, may be misleading. He also highlighted that counterfeiters are now using animal fats, instead of palm fats, in their products, which can be difficult for consumers to detect. Therefore, he recommended buying butter only from trusted brands to avoid falling victim to counterfeit products.
