Is there poison in cucumbers

Cucumbers themselves are not poisonous; they are safe and nutritious to eat. However, cucumber skins can sometimes contain pesticide residues if not washed properly. Additionally, some varieties of cucumbers may have a bitter taste due to compounds called cucurbitacins, which can be mildly toxic in very high concentrations, but this is rare in commercially available varieties. Always wash cucumbers thoroughly before consumption to minimize any potential risks.
