How to Protect Your Grain From Toxins and Mold Fungi

23 September 2024

Grain storage is a critical stage in agricultural production. It’s during this time that the grain, if improperly handled, becomes highly susceptible to mold fungi, which typically thrive due to inadequate preparation or poor storage conditions. These fungi can degrade the quality of the grain, leading to economic losses and potential health risks for livestock and humans. On the other hand, toxins like mycotoxins, which are harmful byproducts produced by certain fungi, often form before grain storage begins, particularly in the field during unfavorable growing conditions such as excessive moisture.

While the origins of toxins and mold fungi differ, they both pose serious threats to grain quality and safety. Fortunately, by understanding the specific risks and applying targeted preventive measures, you can protect your grain effectively. This article will explore the causes and solutions for both mold fungi and toxins, as well as how Metra grain cleaning equipment can play a pivotal role in maintaining a safe and high-quality harvest.

Common Toxins and Fungi in Grain 

Grain can be compromised by various types of molds and toxins, including:

  • Aflatoxin: Produced by Aspergillus molds, aflatoxins are highly toxic and can cause liver damage in humans and animals.
  • Vomitoxin (Deoxynivalenol): A common contaminant in wheat and corn, vomitoxin affects the immune system and can cause serious health issues.
  • Fusarium: This mold produces mycotoxins that can reduce crop yield and grain quality.
  • Ergot: Found in rye, wheat, and other cereals, ergot contamination leads to the production of toxic alkaloids, dangerous for consumption.

These contaminants thrive in humid environments, often during the storage phase. Moisture is a primary culprit, and if grain is not properly dried or maintained, mold growth and toxin production can quickly escalate.

Mold Fungi in Grain Storage

Mold fungi develop primarily due to poor grain preparation and unfavorable storage conditions. These conditions include excessive moisture, improper aeration, and fluctuating temperatures, which create an environment conducive to mold growth. To prevent this:

  • Ensure Proper Drying: Before storage, grain should be adequately dried to reduce moisture levels to a safe range.
  • Optimize Storage Conditions: Maintain stable temperatures and ensure right ventilation to prevent moisture buildup in storage facilities.
  • Regular Monitoring: Continuously check moisture levels and inspect the grain for any signs of mold development.

By following these steps, you can minimize the risk of mold fungi affecting your stored grain.

Toxins in Grain

Toxins, particularly mycotoxins, form primarily before storage, often due to poor growing conditions such as excessive humidity or fungal infections during cultivation. These toxins are challenging to eliminate after they form, but prevention is key:

  • Field Management: Proper field management techniques, including controlling moisture levels and managing pests, can reduce the likelihood of fungi that produce toxins.
  • Early Detection: Testing the grain for toxin levels before storage can help identify contamination early and prevent mixing of contaminated grain with clean stock.

Metra offers advanced grain cleaning and storage solutions designed to tackle the challenges of toxins and mold fungi. By integrating Metra’s equipment into your grain management process, you can effectively mitigate the risks of both issues.

Metra’s aerodynamic cleaners, like the ADS and ADS-CDC models, use air to separate light and heavy impurities, including mold-infected kernels and insects. These machines efficiently remove contaminants without causing damage to the grain.

Here’s how Metra products can safeguard your grain from toxins, funguses and mold using specialized equipment:

  • Fusarium: Metra’s Aerodynamic grain cleaner (ADS) and Aerodynamic grain cleaner with cyclone dust collector (ADS CDC) models efficiently remove Fusarium-infected grains, ensuring higher grain quality and safety.
  • Aflatoxin: Also these systems are designed to separate aflatoxin-contaminated grains, protecting your harvest from this harmful toxin.
  • Vomitoxin: Using advanced airflow technology, the ADS / ADS CDC effectively cleanses grains affected by vomitoxin, maintaining optimal crop health.
  • Fungus: ADS / ADS CDC models are equipped to remove fungal contaminants, preventing the spread of mold and ensuring safe, high-quality grain storage.
  • Ergot: Metra’s Aerodynamic grain cleaner and Aerodynamic grain cleaner with cyclone dust collector and Vibration Grain Cleaners (VDSC) are highly effective in removing ergot-infected grains. The ADS / ADS CDC models use precise airflow to separate the lighter, healthy grains from the heavier, ergot-contaminated kernels, while the VDSC utilizes double-screen technology to ensure thorough removal of these harmful contaminants. This combination guarantees clean, high-quality grain, free from toxic ergot alkaloids. The Metra Color Sorter uses advanced optical sensors to detect the specific color differences between healthy grains and ergot-infected grains.  The sorter identifies these visual anomalies and removes the contaminated grains with precision, ensuring a high level of cleanliness and safety of grains.

Protecting your grain from mold and toxins is a vital investment in your farm’s future. With the right prevention methods and reliable Metra’s cleaning equipment, you can maintain the quality of your harvest and ensure its safety for consumers. 

Metra’s grain cleaning machines are designed to provide farmers with durable, energy-efficient solutions for all types of grain, giving you peace of mind and helping you maximize your yield and profitability.
