[Hygienic basis for using fish treated with crotonolactone as human food].

A hygienic evaluation has been presented of fish bred in pools and treated with commercial crotopolactone for the therapy and prevention of aeromonosis, which was not previously used for this purpose. Basing on the study of the residual amounts of crotonolactone in the fish, of the organoleptic properties, chemical composition and biological value of the fish, as well as on the results of a chronic (12 months) experiment on test animals, the authors have made a conclusion on the possibility of using this fish as food for humans. Certain doses of commercial crotonolactone are recommended for the treatment of aeromonosis in fish.
