25-Year-Old Man Suffers Kidney Failure After Just One Bite

Understanding why this happens requires a look at plant biology and environmental factors. A primary culprit is cross-pollination. If a cultivated, mild variety of squash or cucumber is pollinated by a nearby wild, bitter variety, the resulting fruit can inherit high levels of these defensive toxins. Additionally, environmental stress plays a significant role. When plants face adverse conditions such as severe drought, unusually high temperatures, poor soil quality, or nutrient imbalances, they may produce elevated amounts of cucurbitacins as a natural defense mechanism to protect themselves.
