A study found Wednesday that organic milk products cost up to three times more than standard milk products despite containing no fewer harmful substances or bacteria . Consumers Korea released its study on organic milk products of three major diary companies including Namyang Diary Products Co . and Pasteur Milk . “ There was actually no difference between organic and standard milk products , ” the group said in a news conference at the building of the Fair Trade Commission in southern Seoul . The group conducted the study between June and August and was sponsored by the state - run antitrust regulator . According to the group , standard milk products surveyed did not contain bacteria , colon bacillus , antibiotics or pesticide residue when compared to organic milk products . However , the prices of organic milk products were 1 . 8 to 2 . 6 times higher , the study found . Even though companies often cite the high costs for organic feed , the group said they are making excessive profits . “ Producers say that organic feed costs are 50 to 60 percent more expensive than ordinary ones paying an additional 540 won ( 5 cents ) per liter to diary firms , ” the group said . “ However , that cannot be an excuse for them to double or triple the product prices , ” the group said , urging a price reduction in organic milk products . The group also found no difference in the composition of other specialty milk products claimed to contain more vitamins or calcium . A vitamin A - enriched milk product manufactured by Seoul Milk actually contained 65 percent less of the nutrient compared to the company ’ s standard milk product . Based on their findings , the group plans to request that the FTC take follow - up measures . “ We are considering launching an investigation into the advertising strategy of premium milk products , ” said a FTC official .
