A new processing plant was constructed on the north side of Bridgeton which opened in March 1955.  It was the newest dairy plant in the area and the company's first by-line was formed: "South Jersey's Most Modern Dairy."  In January 1985, Cumberland Dairy began operation of the first United States installation of the DASI Ultra High Temperature Pasteurization System.  This system was the first UHT system that can give dairy products a longer shelf life through sterilization, but still maintain a fresh flavor.  In 2004, Cumberland Dairy continued to be a leader in the dairy by installing one of the first plastic milk bottling lines exclusively for ESL refrigerated dairy products.
