Cloverleaf Cold Storage Company privately held warehouse company offering public and contract storage in refrigerated, frozen ... , and dry environments. All Cloverleaf warehouses are food grade facilities and over 99% of company throughput is related to the food processing, food service, and retail business. Cloverleaf Cold Storage began providing refrigerated warehouse services to the food industry more than 60 years ago in Mankato, Minnesota, but company history goes back further. The company began as the Farmers Produce Company in Sioux City, Iowa in 1934. This company collected poultry and eggs from local farmers for packing and shipping to nationwide markets. By 1958, Cloverleaf had also developed freezer warehouses in Sioux City, in addition to Mankato, and in the following years the company expanded through new development and joint ventures with its customers. Cloverleaf has been an innovator in the industry: building the first rack-supported freezer in the United States, and the first large-scale urethane panel warehouse. It was one of the first to adopt cantilever and push-back rack designs. Cloverleaf first began passing EDI transactions with its customers in 1989 and using bar code pallet tracking in 1991. Today, Cloverleaf is one of the largest privately held public refrigerated and dry warehouse companies in the United States. read more
