A Good Mycotoxin Test Begins with A "Representative" Sample!

The importance of collecting a "representative" sample can not be overestimated. Almost all (90%) of the variability associated with mycotoxin test results comes from incorrect sample collection. Although taking a sample from the top of a storage bin, truck or combine may be easy and very convenient, you will most likely not be happy with the results since mycotoxin distribution is rarely distributed evenly in a load of corn.

If the sample is come from a bin, truck, V-box, or other stationary load of corn, a sample probe is recommended. Although 10 probes are recommended, 5 probes will do if necessary. Mix the grouped sample and take a representative sample from this pooled sample. If you are dealing with a moving stream of grain, either use a diverter or randomly collect cupfuls (handfuls will work as well) of grain. Regardless of how the sample is taken, it must be processed quickly! Therefore ship or deliver the sample promptly. The longer the sample sits around the greater potential of an inaccurate result.

When it comes to sampling and an accurate mycotoxin test - the more sample taken the better!
