Abstract:

Mycotoxin contamination in food grains poses a severe threat to food safety, public health, and rural livelihoods, particularly in flood-affected regions where high moisture and temperature fluctuations create ideal conditions for fungal proliferation. This study investigates the prevalence, environmental drivers, and mitigation strategies for mycotoxins in major food grains collected from the flood-prone areas of Bhojpur district, Bihar. Field sampling was conducted across multiple villages, followed by systematic laboratory analyses using High-Performance Liquid Chromatography (HPLC), Enzyme-Linked Immunosorbent Assay (ELISA), and Thin Layer Chromatography (TLC) to quantify toxins such as aflatoxin B?, ochratoxin, and fumonisins. Moisture–temperature interactions were closely monitored, revealing a strong positive correlation between moisture levels above 12–14% and the rapid multiplication of Aspergillus, Penicillium, and Fusarium species. The study also evaluated eco-friendly mitigation interventions including bio-preservatives, antifungal botanical coatings, hybrid solar-mechanical drying systems, and hermetic storage technologies. Quantitative results demonstrated substantial reductions in fungal contamination (35–62%) and toxin production (40–60%) when these strategies were implemented. A detailed cost–benefit analysis confirmed the economic viability of preventive measures for rural communities, with post-harvest losses reduced by 30–45% and grain marketability significantly improved. Based on these findings, a comprehensive Preventive Strategy Framework was developed, incorporating five key steps: hygienic collection, scientific drying, periodic monitoring, safe storage, and community training. This model integrates scientific techniques with local feasibility, enabling farmers to adopt low-cost, scalable practices that enhance grain quality and reduce health risks. Training modules and community engagement played a crucial role in ensuring long-term adoption and resilience.
