Fumonisin B1 is primarily studied for its impact on agriculture and food safety due to its role as a mycotoxin. It is commonly found in maize and maize-based products, where it poses a significant risk to both human and animal health. In agriculture, it is crucial to monitor and control its presence to prevent contamination of crops, particularly in regions where maize is a staple food. In the food industry, strict regulations are implemented to limit its levels in products, ensuring consumer safety. Research is also focused on developing methods to detoxify or reduce its presence in contaminated food. Additionally, Fumonisin B1 is used in scientific studies to understand its toxicological effects, particularly its association with diseases such as esophageal cancer and neural tube defects in humans, as well as liver and kidney damage in animals. This research aids in developing strategies to mitigate its harmful effects.
