2、he case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe purpose of this guide is to present information on the use of ionizing radiation for e
3、liminatingor reducing the number of pathogenic microorganisms and parasites and for reducing the number ofspoilage microorganisms on finfish and aquatic invertebrates.Information on the handling of finfishand aquatic invertebrates before receipt by the irradiation facility and after shipment from th
4、e facilityis also provided.This guide is intended to serve as a set of recommendations to be followed when using irradiationtechnology where approved by an appropriate regulatory control authority.It is not to be construed assetting forth rigid requirements for the use of irradiation.While the use o
