Natural Toxins Foods can contain natural toxins as a result of product spoilage, damage and mold growth. Common plant-based toxins such as lectins (found in many types of beans), glycolalkaloids (found in potatoes), and trypsin inhibitors (found in soybeans) are not toxic in humans unless consumed in high amounts. Contamination of fish with toxins can occur from naturally occurring marine algae (phycotoxins) and many fungi and mold can excrete natural secondary toxic compounds called mycotoxins which exert harmful effects in humans and animals at very low levels. Bacteria can also produce toxins such as Vibrio cholerae, the bacterium responsible for cholera which is transmitted by the ingestion of raw or undercooked seafood and drinking contaminated water. Conventional analytical methods for the detection of toxins typically include chromatographic techniques which can be slow and expensive since they require highly-trained personnel and costly equipment. The need for simple, rapid, and cost-effective methods for detecting natural toxins that can be handled on-site, have become increasingly important to food manufacturers in order to keep commodities and products moving rapidly through the marketing channels, saving time and money. The advance of immunological techniques is becoming more useful for toxin detection due to their improved specificity and sensitivity.
