Alternatively, a manual approach involves cutting through the moving stream with a cup or scoop. In this manual approach, it is crucial to identify the precise location for sample collection. Collecting as many samples as necessary, altering the position of the cup or scoop with each extraction, ensures a comprehensive representation of mycotoxin distribution within the product stream. These precise sampling practices adhere to industry standards, showcasing a commitment to accuracy in mycotoxin analysis. By incorporating these techniques during transfer, researchers and professionals can elevate the reliability and accuracy of their findings, contributing to a more robust understanding of mycotoxin presence in agricultural products. SAMPLING FROM STORAGE TRUCKS, BUNKERS AND BAG SILOS When sampling from storage or trucks, collect incremental samples (100 g) from various places distributed throughout the lot where the grain is accessible. The minimum length of the sampling probe should be two meters. For bunker and bag silos, collect incremental samples by puncturing the plastic cover using a sharp, cone-shaped sampling device. Holes should be evenly distributed over the entire surface of the silo (Figure 2). Refill each hole cautiously immediately afterwards and cover using a strong tape to prevent possible contamination. OPTIMISING STORAGE CONDITIONS Storage conditions significantly impact mycotoxin levels. Proper storage practices, including temperature control and moisture management, help prevent mycotoxin development. Millers should prioritize optimal storage conditions to minimize contamination risks. MYCOTOXIN TESTING TIPS • Sampling should be conducted on a regular basis. • Every new batch should be sampled. • Improper storage may affect the quality of grain. ESTABLISHING A MYCOTOXIN MITIGATION STRATEGY A comprehensive strategy is essential for managing mycotoxin risks. Millers should consider the following steps: • Testing Program: Implement a robust mycotoxin testing program. Regular testing of raw ingredients ensures early detection and timely intervention.
