Abstract

The present study was carried out to assess the microbial quality of fish processing industries effluent at Bhidia  bar- mouth, Veraval, Gujarat during April, 2012 to March 2013. The total viable bacterial count (TVBC), total Enterobacteriaceae count, E.coli count (EC), Staphylococcus aureus and Fecal Streptococcal count in effluent ranged from 3.0 x 10¹ to 6.8 x 10⁶, 9.0 x 10¹ to 2.9 x 10⁴, 0 to 0. 5 x 10⁴, 0 to 0. 4 x 10² and 0.3 x 10¹ to 0. 1 x 10⁴ cfu.ml^-1, respectively. Significantly higher load of TEC, E.coli, S.aureus, Fecal Streptococci, Total coliforms and Fecal coliforms were higher during summer whereas, TVBC was higher in the month of Sept.-Oct. Furthermore, the total coliform and fecal coliform counts were found to be higher with 1400+ /100ml MPN value throughout the year of the study, except in the month of August. Overall occurrence of pathogenic strains of E.coli, S.aureus and Fecal streptococci were 41.67%, 25.00% and 66.67% respectively during this period. The antibiogram of the isolated E.coli isolates show that almost 50% were resistant to Cefazidime/ Clavulanic acid (CAC), Amoxyclav (AMC), Ciprofloxacin (CIF) and Ampicillin (AMP). The present study indicated that the effluent of fish processing industry was heavily contaminated with E.coli, S. aureus and Fecal Streptococci which confirmed improper treatment of fish processing effluent. Moreover, the precedence of antibiotic resistant E.coli may pose threat to public health safety.  Â Â
