Studies were undertaken to isolate and identify filamentous fungi from gable‐top cartons used for fruit juice packaging. All containers studied were food‐grade, gable‐top cartons composed of paperboard with various laminants and coextruded layers. Paperboard fibers from surface sterilized pieces of blank (unfilled) cartons harbored 40 species of 14 genera and 6 Mycelia Sterilia isolates. A parallel study of juice‐filled cartons revealed 10 filamentous species and 3 Mycelia Sterilia isolates from deteriorated areas of the paperboard cartons. Three of 9 juice‐filled cartons contained mycelial mats of Penicillium biforme and Penicillium spinulosum within the juice. These two species were also isolated from the paperboard.
