Abstract

Evaluation oj sensory. cite mica I and microbiological status oj smoked herring sold
in supermarkets in Egypt was carried oui. Twenly five random samples oj smoked herring
were taken and transferred dlrectJu 10 t!:e iabora/on) under aseptic conditions with

examinations. The obtained results reveo.led /hat} 6 % oj samples were rejected
due to higher total bacterial counl; 44% rejectedJor presence S. aureus count, 32 % reJected

The data also reuealed that one COIl depend on smoklrtg to mirlimlze growth oJspoUage
