Abstract

The aim of this research is to determine the quality and proximate composition of Amaranthus hybridus check for this species in other resources , Celosia argentea check for this species in other resources , and Talinum triangulare check for this species in other resources obtained from open markets in Benin City, Nigeria. Microbiological and proximate analysis were carried out using standard methods. Results of the proximate analysis revealed the presence of proteins (12.86 ± 0.19 %; 9.28 ± 0.07 % and 2.82 ± 0.08 %), carbohydrates (9.06 ± 4.19 %; 8.28 ± 0.48 % and 12.22 ± 0.53 %), fibre (10.38 ± 0.25 %; 8.45 ± 0.13 % and 3.55 ± 0.17 %), lipids (0.23 ± 0.13 %; 1.44 ± 0.28 % and 1.06 ± 0.28 %), moisture (62.38 ± 4.05 %; 62.98 ± 0.38 % and 79.65 ± 0.56 %) and ash (mineral content) (5.10 ± 0.14 %; 9.58 ± 0.05% and 0.70 ± 0.12 %) in the green leaf, soko and water leaf respectively, needed for normal functioning of the body. However, microbial contaminants were observed which included bacterial and fungal species. The bacteria isolated were: Staphylococcus aureus check for this species in other resources , Bacillus subtillis check for this species in other resources , Enterobacter check for this species in other resources sp, Klebsiella check for this species in other resources sp, Proteus vulgaris check for this species in other resources , Pseudomonas aeruginosa check for this species in other resources and Escherichia coli check for this species in other resources , while the fungal species isolated were: Rhizopus stolonifer check for this species in other resources , Aspergillus niger check for this species in other resources , Fusarium solani check for this species in other resources , Aspergillus flavus check for this species in other resources , Mucor mucedo check for this species in other resources , Penicillium notatum check for this species in other resources , and Penicillium expansum check for this species in other resources . The bacterial count, coliform count and fungal count of A. hybridus were: 1.19 x 105 ± 4.52 x 104 cfu/g, 3.30 x 104 ± 1.82 x 104 cfu/g and 6.50 x 103 ± 3.32 x 103 cfu/g respectively. C. argentea had 1.56 x 105 ± 7.00 x 104 cfu/g, 3.88 x 104 ± 2.56 x 104 cfu/g and 6.00 x 103 ± 3.74 x 103 cfu/g respectively, while T. triangulare had 1.99 x 105 ± 9.31 x 104 cfu/g, 4.93 x 104 ± 4.77 x 104 cfu/g and 4.78 x 103 ± 2.18 x 104 cfu/g respectively. Antibiotic susceptibility pattern of the bacterial isolates revealed multi-drug resistance and plasmid-mediated resistance genes among the isolates. Public enlightenment, proper washing and cooking with potable water are therefore recommended to avoid the menance of these multi-drug resistant microbial contaminants.
