TAPPI T449 – Bacteriological Examination of Paper and Paperboard

The following procedure is recommended for the bacteriological examination of paper and paperboard intended for use as single service containers and closures for dairy products. Because of the exacting technique required in bacteriological procedures, reproducible results can be obtained only by a trained technician. All tests should be performed under the appropriate laboratory conditions to ensure quality assurance and safety.

This method is important because it provides a procedure for determining the number of colony-forming units (CFU’s) per gram of paper or paperboard in accordance with the requirements of the Dairymen’s Standard as published by the U.S. Department of Health and Human Services, Public Health Service, Food and Drug Administration.
