Innovative Solutions to Combat Mycotoxins in Feed and Milk
Seeing the Invisible
Traditional methods of mycotoxin detection often involved time-consuming laboratory processes that required extensive sample preparation and skilled technicians. Today, a technological revolution is transforming how we identify and measure these dangerous contaminants, making detection faster, more accurate, and accessible.
This cutting-edge technology uses advanced optics to analyze the surface and spectral characteristics of grains without any grinding, chemicals, or preparation.
Enhanced with quantum dot technology, these handheld devices allow for on-site testing of samples without relying on laboratory turnarounds.
By analyzing weather patterns, crop stress, and historical contamination data, AI models can help teams test more strategically.
Research has demonstrated that AI significantly improves predictive performance compared to traditional models 8 .
Once detected, contaminated products require effective decontamination strategies. Researchers have developed an impressive array of physical, chemical, and biological methods to eliminate or reduce mycotoxins without compromising product quality or safety.
Recent studies have explored the effect of microwave (MW) and ultraviolet (UV) treatments on mycotoxin degradation in rice, with promising results for other commodities too.
Adsorption technology uses specialized materials to capture and remove mycotoxin molecules from contaminated products.
Certain microorganisms, including specific strains of bacteria and yeast, can bind or transform mycotoxins into less toxic compounds.
Nanomaterials offer promising, efficient, and low-cost ways to minimize mycotoxins' health effects.
Testing Microwave and UV Treatments
To understand how scientists evaluate decontamination methods, let's examine a specific experiment that investigated the effectiveness of microwave and ultraviolet treatments in reducing mycotoxin levels in rice 1 .
Rice artificially contaminated with known concentrations of three mycotoxins: AFT (50 ng/g), AFB1 (50 ng/g), and OTA (20 ng/g).
Samples treated at three power levels (560W, 640W, 720W) for two exposure times (120s, 360s).
Samples exposed to UV light at 15 mW/cm² for varying durations (0.5-4 hours).
Remaining mycotoxin levels measured using HPLC-FLD.

|---|---|---|
| AFT | 560W, 120s | 33.40% |
| AFT | 720W, 360s | 40.00% |
| AFB1 | 560W, 120s | 50.06% |
| AFB1 | 720W, 360s | 49.31% |
| OTA | 560W, 120s | 75.24% |

As mycotoxin management evolves, researchers and industry professionals are recognizing that no single solution provides complete protection. Instead, the future lies in integrated systems that combine multiple approaches throughout the entire production chain—from field to fork.
Cargill's Mycotoxin Impact Calculator (MIC) helps quantify economic and performance risks associated with mycotoxin exposure 4 .
76-78% of feed samples contain multiple mycotoxins simultaneously, creating potential additive or synergistic effects 9 .
HACCP-based systems identify critical control points to address mycotoxin risks at their source rather than reacting to contamination .
This comprehensive approach—combining predictive AI models, rapid detection technologies, and targeted decontamination methods—represents the most promising path forward in our ongoing battle against these invisible contaminants.
Cargill's database includes over 400,000 analyses from more than 150 locations worldwide to provide real-time, location-specific risk insights 4 .
The fight against mycotoxins represents a remarkable convergence of traditional agricultural knowledge and cutting-edge technology. From AI-powered prediction models to nanotechnology-based decontamination, scientists are developing increasingly sophisticated tools to ensure our food supply remains safe and nutritious.
While challenges remain—including the emergence of new mycotoxin variants and the complexities of co-contamination—the innovative approaches highlighted in this article demonstrate our growing capacity to manage these invisible threats. As research continues to advance, we move closer to a future where mycotoxin contamination becomes a manageable risk rather than an unavoidable hazard, protecting both animal and human health throughout the global food system.
The next time you enjoy a glass of milk or a bowl of rice, remember the invisible scientific revolution that helps ensure these staples remain safe, from farm to table.
