Evaluation of microbial and physical properties of frozen Roho Fish Laberohita and Mrigal Fish Cirrhina mrigal from local markets in Basrah

Abstract

The present study aimed to evaluated microbial and physical quality of frozen Rohu fish(Labeo rohita) and mrigal fish (Cirrhina mrigal) that prepared from local markets of Al- Basrah (Al-Ashar , Al-Basrah , Al-Jemhoriae ) ,The samples were collected during December (2011), January , February , April , May , June(2012) . Physical characteristics (pH ,Water Holding Ability and Drip ) were studied and the changes in microbiological indicators (Total bacterial count , Total coliform bacteria , Staphylococcus aureus count , Detection of Salmonella and molds and yeasts count). Were also studied the results showed that there is significant effect of fish species , period and location samples and the interference between fish species and location, and between fish species and period samples and between location and period samples prepared and effect interference between fish species and period samples prepared and ocation the mean value by depending on R. L. S. D. at (0.05)on physical and microbial properties .There is significant differences (P< 0.05) in Water Holding Ability Value , Drip loss and pH to samples to rohu and mrigal fish frozen and prepared from the markets,The results also showed that there is significant effect (P<0.05) in Total bacterial count , Staphylococcus aureus count , molds and yeasts count , but there is no significant effect in Total coliform during study periods
