What is toxic squash and how does it become toxic?
Toxic squash refers to certain types of squash, such as zucchini, acorn squash, and pumpkins, that can become contaminated with a group of compounds called cucurbitacins. These compounds are naturally produced by the squash plant as a defense mechanism against insects and other predators. However, when the squash becomes overripe or damaged, the levels of cucurbitacins can increase to toxic levels.
The exact mechanism of how squash becomes toxic is not fully understood, but it is believed that the breakdown of the cell walls in the squash allows the cucurbitacins to become more concentrated. This can happen when the squash is past its prime, has been damaged during handling or storage, or has been infected with a fungus or bacteria. As a result, it is essential to handle and store squash properly to minimize the risk of toxicity.
What are the symptoms of toxic squash poisoning?
The symptoms of toxic squash poisoning can vary depending on the amount and type of squash consumed, as well as the individual’s sensitivity to cucurbitacins.
