Improvements in sanitation of flumes or dump tanks in packinghouses

Michael J. Mahovic, Jerry A. Bartz

Abstract


The sanitation of water systems used packinghouses is critical to the production of wholesome, healthy products. Currently, water chlorination with a specified temperature and pH is recommended. Alternatives have been proposed with claims of better efficacy, increased safety, and greater ease of use. In selecting alternatives for potential use, several key factors must be considered: Is use of the product safe? Is the product effective? Will the product be cost-effective? Several products were selected for initial tests as a chlorination alternative: ultraviolet light irradiation; ozone; chlorine dioxide; and acidified sodium chlorite (ASC). Even with promising control levels, physical limitations suggested none of these would be suitable tank sanitizers. Alternative delivery methods for ASC and chlorine dioxide are currently being tested. While standard chlorination is still the recommended treatment regarding a number of variables, future alternatives are being explored. Such alternatives should be scrutinized for effectiveness and practicality, but should not be dismissed without proper evidence.
