Existence of faecal coliforms and faecal streptococci in frozen food (Meat and vegetables) products

In this study, frozen 20 meatball, 20 ground meat, 20 meat cut in small chunks,20 broccoli, 20 peas and 20 cauliflower, in total 120 meat and vegetable samplescollected from various supermarket of Ankara between dates of 1.10.2004 -30.10.2005. isolated 63 isolates were identified as belonging to the genusEnterococcus. 40 (%33,3) Faecal streptococci isolates isolated from frozen meatand vegetable samples, after carbonhydrate and biochemical tests isolates wereidentified as 28 (%70) E. faecalis and 12 (%30)?i E. faecium. After identificationprocedures used on 290 Koliform isolates, isolated from frozen meat andvegetable samples 76 (%26.2) isolates were identified as Escherichia coli.23(%38,3) isolates isolated from 60 meat samples as belonging to faecalstreptococci were identified as 17 (%73,9) E. faecalis ve 6 (%26,1) E. faecium.Reply to faecal streptococci counts, after identification procedures used with all141 Koliform isolates isolated from 60 meat samples, 31 (%22) isolates wereidentified as Escherichia coli. 17 (%28,3) isolates isolated from 60 vegetablesamples as belonging to faecal streptococci, were identified as 11(%64,7) E.faecalis, ve 6 (%35,3) E. faecium. Again reply to faecal streptococci counts, afteridentification procedures used with all 149 Coliform isolates, isolated from 60vegetable samples 45 (%30,2) isolates were identified as Escherichia coli.viiTotal aerob and Staphylococcus aureus counts have been also evaluated in thisstudy.Science Code : 203.1.010Key Words : Frozen meat and vegetables, Enterococcus, Coliform,E. coliPage Number : 88Adviser : Assoc.
