The Biglerville plant, which started in 1905 as the Biglerville Canning Company, canned tomatoes, corn and apples from the surrounding farms. After operating at a loss, it was sold to the Musselman family in 1907. Christian H. Musselman and his wife, Emma, had gained early notice during World War I when their plants at Biglerville and Gardners managed to maintain a steady flow of canned fruit despite labor, fuel and transportation shortages. During the 1960s and 1970s, the company became part of the PET Foods Company. C.H. Musselman went on to produce canned foods during World War I, adding red tart cherries and peaches to the list. Musselman merged with the PET Milk Company in 1961. In the following years, the plant continued to process local fruits and vegetables, making juice, sauce, jelly and taco sauce. In 1979, IC Industries Company purchased the PET Milk Company including Musselman.
In 1981, IC Industries sold the Musselman Division to private owners, who changed the name to Musselman's Fruit Products. They sold Musselman's to Knouse Foods in 1984.
Today, the plant produces apple juice, sparkling cider, sliced apples, pie fillings, vinegar, fruit cobblers and apple butter. In fact, Biglerville is the only Knouse plant to make this delicious apple butter from a process that is nearly 100 years old!
