37. Cooking or processing maize does not completely eliminate Fumonisin B1.
38. Fumonisin B1 can also contaminate other crops like sorghum and rice, though less commonly.
39. The toxin can persist in soil, posing a risk for future crops.
40. Some traditional maize processing methods, like nixtamalization, can reduce Fumonisin B1 levels.

Final Thoughts on Fumonisin B1

Fumonisin B1, a toxin produced by Fusarium fungi, poses significant risks to human and animal health. Found in contaminated maize and other crops, it can cause serious diseases like esophageal cancer in humans and leukoencephalomalacia in horses. Regulatory bodies worldwide have set strict limits on fumonisin levels in food and feed to protect public health. Awareness and proper agricultural practices can reduce exposure to this harmful toxin. Regular monitoring and testing of crops ensure safety and compliance with regulations. Understanding fumonisin B1's impact highlights the importance of food safety and the need for ongoing research. By staying informed and vigilant, we can minimize the risks associated with this toxin and promote healthier, safer food supplies.
