Samples of naturally contaminated hulled barley, with varying deoxynivalenol concentrations, weresubjected to an abrasive type dehulling procedure. The remaining grain fractions were analyzed forweight remaining (%), deoxynivalenol (ppm), crude protein (%CP), neutral detergent fiber (%NDF),ash (%ASH), gross energy (GE; kcal/kg), and calculated digestible energy values (DE; kcal/kg).Following the initial 15 s of pearling, 85% of the grain mass remained. Additional pearling resulted ina linear decline of grain mass. Following 15 s of pearling, the grain contained 34% of the initialdeoxynivalenol content, irrespective of the initial level of contamination. Further pearling resulted incontinued significant (p < 0.05) reductions in the percent of deoxynivalenol remaining to a level of7.9% after 120 s but with significant losses in grain mass. Pearling can serve as an effective meansof reducing the deoxynivalenol content of barley, with improvements in nutrient levels. However, theneed to reduce the deoxynivalenol content of contaminated barley to less than 1 ppm for swine willnecessitate the removal of a significant amount of the grain mass for heavily contaminated samples.Keywords: Mycotoxin; decontamination; Fusarium
