Genetically modified (GM) potatoes with silenced melanin genes may mask diseases during processing, leading to hidden health risks. For example, non-browning bruises in GM potatoes contain tyramine, which can cause hypertension and other issues in some individuals. Additionally, these GM potatoes can conceal tuber infections, allowing toxic compounds like chaconine-malonyl and pathogens like AAL-toxin to accumulate, potentially affecting wild-type potato plants.
