FOOD PROCESSORS AND OTHER NON TRANSPORT INTERMEDIARIES FRUIT AND VEGETABLE FIRMS Packing Houses Packing houses have already been described to some extent in the preceding section. These tend to be family-owned facilities that sort, clean, and package fresh produce. The facilities are usually specialized to handle one or a few products. The operations are labor intensive, reflecting the relative costs of capital and labor in Mexico. In addition, packers frequently minimize mechanization due to perceived social obligations to keep workers employed. The traditional sector packs for the traditional portion of the domestic market. This market is interested in low-cost produce that will be consumed within 24 hours of purchase. Only minimal sorting, grading, cleaning, and packaging occurs. The buyer expects to choose the fruit from a mixture of sizes. The role of the traditional packing sector is to get the produce to the central market as cheaply as possible. Any mechanization that exists in such facilities is minimal and usually old. Boxes are rarely new and are often made of wood. The modem packing houses pack either for the U.S. market or the top of the Mexican market. Only produce that fails to meet quality standards would go to the traditional Mexican market. These firms grade, clean, and package to U.S. standards since the produce must compete with U.S. produce directly. Almost all cartons and much of the machinery are made in the United States. These packing houses are generally large, in part because of the minimum size required to gain market access in the U.S. market. Also, the managerial requirements of running a top-of-the-line facility and coordinating its operation with the farm production are sizable and only within the abilities of a large firm.
