Detection of microbial contaminants of some locally produced fruit juices, ice creams, and yogurts.

Abstract

Abstract:The study included (45) samples of fruit juices, ice creams and yogurts which locallyproduced and available at Baghdad markets including some small markets and booths. Thestudy focused on the detection of microbial contaminants by accounting total number ofaerobic bacteria, coliform bacteria, E.coli, S. aureus and Salmonella.Results of microbial tests of (20) randomly collected samples of juices selected fromlocal stores and boxes in Baghdad city area showed contamination and invalidity of thesesamples for human consumption comparing to Iraqi standards with a failure rate reached to 15% for total count of bacteria, 10% for coliform.The microbial test (15) samples showed a failure rate of 66.5% for aerobic bacteria(T.C) , 60% for E.coli, 65.6 % for coliform bacteria , 13.3 % for staphylococcus aureus.No sign if Salmonella existence was recorded for all tested samples in compare with Iraqistandards. As for yogurts, the microbial tests of (10) samples showed a failure rate of 30% forcoliform, no sign of Salmonella existence was recorded for all tested samples.
