Fumonisin B3 (FB3), a less commonly studied but significant mycotoxin, is an important marker in Total Tox Burden panels, reflecting potential exposure to toxins produced by Fusarium species, predominantly found in maize and its by-products. Structurally, FB3 is similar to other fumonisins like B1 and B2, but it is often present at lower concentrations in contaminated foods. Its inclusion in tox burden assessments is crucial due to its potential health implications. Although FB3's toxicity is generally considered to be lower than that of fumonisin B1, it still poses health risks, particularly hepatotoxic and nephrotoxic effects, and it may play a role in esophageal cancer and neural tube defects. The presence of FB3 in a Total Tox Burden panel indicates exposure to Fusarium toxins and necessitates the examination of dietary intake, especially corn-based products, which are the primary source. Preventive strategies focus on agricultural practices to limit fungal contamination and post-harvest interventions to reduce mycotoxin levels. Current research into FB3's biological effects and its interactions with other mycotoxins is essential for understanding its full impact on human health and for the development of more effective detection and detoxification methods. This is particularly relevant as global climate change may alter the distribution and prevalence of Fusarium species, potentially leading to increased exposure to fumonisins, including FB3.
