BMP: Grinding the entire 10 pound sample (diagram 1) and follow diagram 2 during sample reduction to preserve its representative property. The final sample should be ground finely enough that 70% will pass through a 20 mesh sieve. Use GIPSA verified test kits listed in Table 1 or AOAC official methods when analyzing mycotoxin. For quantitative tests, note the kit testing range and dilute samples that exceed the upper limit and re-analyze the sample.

**If a composite sample is required, adjust portion sizes as needed to obtain an adequate size composite sample and still maintain individual file sample
