GMO components detected in South Korean tofu and soy milk

Genetically modified organism (GMO) components have been detected in various processed soybean products sold in South Korea, including tofu, soy milk, and soybean paste. According to data from the Ministry of Food and Drug Safety obtained by Representative Song Ok-ju of the Democratic Party, 68 out of 492 tested items (13.8%) contained GMO elements.

Specific findings showed that 13.8% of tofu samples and 33.3% of processed soy milk samples tested positive for GMOs. Soybean pastes also showed detection rates of 20% for standard paste and 50% for mixed pastes. In contrast, traditional Korean soybean paste and cheonggukjang showed no GMO presence.

The current testing method is qualitative, meaning it can identify the presence of GMOs but cannot determine the exact concentration. This limitation exists because there is currently no established quantitative analysis method for processed foods under existing regulations.

Representative Song has called for an expansion of the mandatory GMO labeling system, similar to Taiwan's model, to include products like tofu, soy milk, starch, and meat alternatives. She noted that while the government plans to apply full labeling to sugars and oils, these essential soybean products are currently excluded. The issue of 'unintentional mixing' during bulk shipping remains a challenge, as most detected levels fall below the current 3% regulatory threshold for mandatory labeling.
