The Best Mycotoxin Tests to Detect Toxins in Crops

Written by Niko Simos | January 23, 2025

 


 

Mycotoxins are a silent but deadly threat to the agricultural world. These naturally occurring compounds are the metabolic products of certain fungi and can compromise the health and quality of various crops. Farmers producing harvests contaminated with fungi and invisible organic particles risk selling unsafe food. They may face financial ruin unless they use the best mycotoxin tests to check and certify their produce is safe. 

Understanding and addressing the mycotoxin threat is crucial for farmers. It can help them better protect their crops while preserving yield and ensuring food safety. 

In this article, you will learn about the best analysis readers on the market and discover how they can help combat the unseen threat to public health and crop quality. 

What Are Mycotoxins? 

Mycotoxins are toxic metabolic byproducts of fungi such as aspergillus, fusarium and penicillium molds. People or animals that eat food contaminated with these particles can develop health problems and diseases affecting the immune and central nervous systems. For those who already have an underlying health condition, exposure to these biologically harmful components can significantly worsen their health and increase side effects. 

Crops like grains, peanuts, coffee beans, and tree nuts are often contaminated by mycotoxin-causing fungi during growth, harvest and storage — especially during droughts and when the weather is hot and humid. Even dried fruit and spices are at risk of contamination. Animals that consume infected feed develop toxic fungal metabolites, which can poison people who eat the meat.

Under optimal fungal growth conditions, the harmful spread of these biological byproducts is rapid. Warm temperatures, high humidity and moisture spur fungal development, which infects food and releases poisons. Farmers must adopt strict safety protocols, such as drying crops thoroughly, using ventilated storage with moisture control and preventing mold contamination. 

Why Are Mycotoxins Harmful?

Mycotoxins harm people and animals because of health risks, while the compounds affect crop quality and can lead to substantial financial loss. 

  • Health risks: Mycotoxins contaminate food and any surfaces they encounter. Even handling contaminated crops can expose people to ingestion of these harmful compounds. Studies have found aflatoxins linked to liver cancer, while fumonisins may be connected to neural tube defects and esophageal cancer. 
  • Economic impacts: Contaminated crops lead to significant financial losses to farmers and agricultural investors. Preventive treatments and measures can increase production costs. Early detection can save money by avoiding harvesting infected crops and also aids in detecting and treating fungal signs. 
  • Regulatory standards: While several hundred types of mycotoxins may contaminate food, the World Health Organization (WHO) and United Nations’ Food and Agriculture Organization (FAO) research teams have established the maximum tolerable levels for exposure to these fungal byproducts. 

The Consequences of Mycotoxin Contamination

Children and older adults are most vulnerable to diseases caused by contamination. Long-term effects of exposure remain a subject of ongoing research. Regular monitoring is critical to prevent the spread of disease-causing fungal byproducts. It’s impossible to reverse fungal toxicity in crops, so the focus is on identification and swift action to stop the spread.   

Developing nations that rely on agricultural exports for revenue face unique challenges. Crops that don’t meet stringent quality standards don’t make it to market, disrupting international trade and farmer income. Many small-scale farmers lack access to analysis kits or knowledge on identifying contamination and controlling the spread of harmful metabolites.  

The Importance of Early Detection

Early detection is vital for proactive interventions, such as removing infected produce from a field or greenhouse. A farmer who regularly walks their land and identifies corn with ear rot can quickly intercede and prevent the spread of more harmful compounds. 

Storage facilities with damp flooring can breed fungal growth, but catching it early reduces loss. Remove contaminated bags and check each layer of grain until no mycotoxins appear in test samples. Then, use fresh, dry storage pallets, dry the area and treat it with antifungal agents to prevent further spore contamination.  

Farmers rely on their reputation for quality produce. Regular examination before shipping harvests ensures the best contaminant-free food reaches the market.  

Who Should Test for Mycotoxin Contamination?

Analyzing feed and grains before storage and transportation is essential if you are involved in production or farming. Key stakeholders include:

  • Grain and feed farmers
  • Producers in animal feed industries
  • Grain mills and product manufacturers
  • Food and beverage managers, such as brewers 
  • Inspectors overseeing storage and distribution

Methods to Detect Mycotoxins

Farmers prioritize kits that are sensitive, fast and scalable. Tests must be cost-effective and portable for field use, allowing frequent evaluation of multiple crop areas. Accuracy is critical to avoid false positives or missed signs of contamination. Time is of the essence in handling infections as fungi reproduce rapidly, spreading more spores and dangerous metabolites. 

Farmers should utilize these key testing approaches:

  1. Chromatographic techniques: High-performance liquid chromatography (HPLC) provides precise analysis but requires sensitive professional equipment that can’t withstand field use. Samples are usually collected and sent to a lab for guaranteed evaluation. Gas chromatography (GC) is less common but valuable for detecting specific mycotoxins that may elude other detection methods. 
  2. Immunoassays: Enzyme-linked immunosorbent assays (ELISA) are cost-effective and provide near-instant results, making them ideal for on-site review. These assays detect specific compounds through antibodies that bind to the particles, producing measurable signals. These kits are highly sensitive and versatile, capable of testing various crops and feed types. Farmers often rely on ELISA kits for quick assessments during harvesting and storage, enabling timely decisions to mitigate contamination risks. 
  3. Rapid tests: Lateral flow devices (LFTs), which test a suspension or liquid sample, offer quick and portable inspection with fast results. Usually, a color-changing strip provides the outcome. While they may lack quantifiable data for insurance companies, they typically satisfy regulatory bodies if you use approved types.  
  4. Emerging technologies: Biosensors enable real-time detection and decision-making, while near-infrared (NIR) spectroscopy identifies contamination noninvasively. Using AI for refined data-driven analytics, such as predicting weather-related risks, can help farmers optimize storage conditions and crop management. 

How to Choose the Right Test for Your Needs

Before choosing your best metabolites review method, evaluate your unique budget, needs, processes, portability, power requirements and storage. Determine whether an evaluation kit will work best for your requirements.  

  1. Budget: Some units require additional equipment like centrifuges to get a final reading, and the price may exceed your budget. Always consider whether you only need one test reader and affordable strips or if you have to invest in several add-ons. 
  2. Test needs: Choose a results reader that can easily handle your demands. If you need to review multiple samples quickly, consider how easily you can insert the samples, the scan time and what the incubation time for each check adds up to. 
  3. Test methods and portability: Consider where you will be testing your samples. If you regularly do it from the back of your vehicle, choose a system that requires minimal chemical components to create samples. Buying ethanol or methanol for samples can quickly become expensive. 
  4. Power requirements: Consider whether you need a battery-operated or rechargeable reader. Readers that require power from the main power supply will limit where you can take readings. 
  5. Storage: Determine if you want to keep results on the reader for future reference, download data with Wi-Fi or connect to your computer with a USB cable.
