Abstract Share this page

To determine the degree of contamination of take notes, samples of the notes circulating in different local markets and people of different professions in Khulna region of Bangladesh were collected. Coliforms, the indicator organisms in taka notes were determined by multiple tube method and identified with differential media and data were analyzed. About 80-15% of old two-taka notes were contaminated with total conforms and 16:0% of notes were found contaminated with fecal conforms. But comparatively newer two-taka notes showed that 4313% were contaminated with total coliforms and 512% were with fecal coliforms, suggesting the notion that more handled taka notes were contaminated more intensely even by fecal coliforms. Ten take notes also represented the same pattern of results as two•taka notes, indicating that taka notes may carry enteric pathogens. This study also revealed that porsaline paper notes were easily vulnerable to coliforms contamination whereas polymer paper notes were almost free from conforms suggesting that polymer paper notes are safer to use than porsaline paper notes.
