Locally fermented drinks (Burukutu and Pito) were collected from seven states of North Central, Nigeria and were analyzed for physicochemical and trace metals. The trace metals were analyzed using Atomic Adsorption Spectrophotometric techniques. Its temperature, pH, titratable acidity, specific gravity and alcohol content were 25.3±1.9 – 31.0±1.2oC, 3.90±0.3 – 4.40±1.2, 0.062±0.04 – 0.117±0.07, 0.718±0.00 and 5.71±0.01, respectively for Burukutu. Suspected microbes for burukutu include: streptococcus species, staphylococcus species and entrobacter species, while for fungi include: saccharomyce species, aspergillus species, penicillium species, sporontrichum species, rhizopus species, mucor species, blastomyces species, mould species, paracoccidioicides species and Coccidioidesimmitis. The result for physicochemical parameters for pito include: 28.3±1.1 – 31.0±3.5 0C, 4.60±0.8 –5.30±0.4, 0.102±0.12 – 0.147±0.04, 0.718±0.0 and 5.71±0.00, respectively. In addition to the suspected bacteria in Burukutu, others found in pito include klebsiella species, micrococcus species and salmonella specie. The mean metal concentrations (mg/L) for burukutu include Cd (0.015± 0.035 –0.024 ± 0.02), Cr (0.36 ± 0.02 – 2.16 ± 0.4), Pb (1.20±0.6 – 1.93±0.2), Zn (0.23±0.02 – 0.54 ± 0.5), Fe (2.81 ± 1.2 – 8.12 ± 0.8) and Ni (0.000 ± 0.0 – 0.94 ± 2.1). Trace metal content for pito was also reported. Most of the heavy metals concentration in burukutu and pito were higher than the maximum permissible limit set by the WHO, for drinking water. There was also a significant difference (p<0.05) of metals analysed for burukutu and pito. The daily consumption of these local drinks have been associated with risk of some form of cancer, heart disease, stroke and some other chronic ailments.
