Excerpts from the report: Costs of candling and cartoning eggs at country points were studied as part of a broad program of research designed to help reduce costs of marketing farm products. This report provides information on the comparative costs of two methods of marketing eggs and shows that one of them, under certain conditions, provides opportunities for substantial savings through elimination of unnecessary operations. Study of seven midwestern egg assembly plants showed that large savings in costs result when eggs are candled and cartoned at country plants, compared with costs when eggs are shipped in 30-dozen cases and candled at distant destinations. The savings are contingent, however, on substantial changes in certain procurement practices, plant operations, and marketing channels.
