幾乎所有蔬菜水果都多少含有點自然生成的毒素，這是大自然中生存競爭下植物的防衛機製

Natural toxins in food

• Some natural toxins can be formed in food as defense mechanisms of plants, through their infestation with toxin-producing mould, or through ingestion by animals of toxin-producing microorganisms.
• Natural toxins can cause a variety of adverse health effects and pose a serious health threat to both humans and livestock. Some of these toxins are extremely potent.
• Adverse health effects can be acute poisoning ranging from allergic reactions to severe stomachache and diarrhoea, and even death.
• Long-term health consequences include effects on the immune, reproductive or nervous systems, and also cancer.
