Abstract

A study which aimed at identifying practices of street sugar cane vendors, heavy metals, and microbial food contaminants which could pose a public health risk concern was done in the Kumasi Metropolis in Ghana. Thirty sugar cane vendors were interviewed and representative samples were purchased for analysis. Lead (Pb), cadmium (Cd), copper (Cu), zinc (Zn), manganese (Zn), iron (Fe) were analyzed with AAS. Total coliform, fecal coliform, and E. coli were determined by the standard most probable number method. The sugar cane selling business from the survey is generally dominated by females within the working age group. From the field survey it was realized that packaged sugar cane was patronized mostly in the evening period. Out of the total of 30 vendors, 12 of them just peel the sugar cane and cut into pieces for package and sales while 18 of the vendors washed the product before peeling and cutting it into pieces for packaging. All the metals analyzed were detected in the various samples. The maximum concentration of Pb recorded was 0.193 mg/kg dry weight and the minimum concentration was 0.066 mg/kg dry weight. The estimated mean daily intakes of Pb, Cd, Cu, Zn, Mn and Fe are 1x 10-5, 3 x 10-6, 2.6 x 10-4, 7x 10-5, 1x 10-5, 7x 10-5, 1.7x 10-4 mg/kg bw/day respectively. The health risk assessments (HRI) values of the various metals considered in this study were less than 1. This indicates that individuals will not experience any significant health risk if they only consume metals from these sugar cane examined. Microbial results showed at least one of total coliform, faecal coliform and E. coli determined. E. coli was present in 16.7 % of all the samples analyzed
