Although foreign buyers prefer low-BCFM (broken corn and foreign material) corn, cleaning is not the solution to quality issues associated with U.S. corn cleanliness. The cost of cleaning corn above the current level at the least net-cost locations, both inland subterminals and river elevators, exceeds domestic benefits by $49 million. Because of the breakage susceptibility of corn kernels, the BCFM level in U.S. corn increases as corn moves toward ports. Thus, cleaning at the current level would still need to occur at every point in the marketing channel along with the additional cleaning to lower the BCFM level. The best approach to address the corn cleanliness issue is to reduce breakage susceptibility in corn through careful selection of drying systems and developing genotypes or hybrid varieties less prone to breakage.
