(a)Ordering and distribution of donated foods. The distributing agency orders donated foods through a Web-based system called the Electronic Commodity Ordering System (ECOS). Through ECOS, the distributing agency places orders directly into a centralized computer system. Before submitting orders for donated foods to FNS, the distributing agency must ensure that all school food authorities are aware of the full list of available donated foods, and have the opportunity to provide input at least annually in determining the donated foods from the full list that are made available to them for ordering or selection. The distributing agency must ensure distribution to school food authorities of all such selected donated foods that may be cost-effectively distributed to them, and may not prohibit the use of split shipments in determining such cost-effectiveness.
