Grain Deviations

Deviations affect the ultimate quality of grain


Technical, scientific and economic challenges determine the creation and capturing of value in the grain industry. Throughout handling and storage, the industry must apply strict and uniform practices that will guarantee the correct identification of deviations.

A good knowledge of potential problems is essential to assure the quality of the grains and oilseeds during all stages of intake, storage and out-loading.



Best management practices, as well as systems and technologies, are needed to maintain and assure the identity, purity, integrity, consistency, quality and marketability of these commodities.

Guidelines and recommendations on industry practice regarding best operational management practices and quality management systems must be practically achievable, economically viable and fully accepted in the global market place.
