Abstract/Summary

Thirteen samples of iced juice drinks commonly known in the Philippines as palamig and sold as street food were analyzed for their microbial content to determine compliance with existing food safety standards. The analyses performed consisted of aerobic heterotrophic plate count, test for the presence of coliforms and test for the presence of molds and yeasts. Twelve of the thirteen samples analyzed yielded plate counts which ranged from 3.8 X 10 to 3 X 10 CFU/ml. These 12 samples also tested positive for coliforms and indicated an MPN index of 1100/100 ml. All 13 samples tested positive for yeasts. Comparison of the microbial content of the samples tested with existing microbiological safety standards of the Bureau of Food and Drugs of the Department of Health for juice drinks packed in plastics showed non-compliance of the iced juice drinks or palamig with existing standards.
