The objective of the present study was to determine the correlation of microorganisms isolated from amaranth to that isolated from soil and irrigation water. Samples of amaranth, soil and irrigation water were collected in dry and wet seasons of 2016 from farm sites in Koriko, Bassa LGA, Kogi State for microbial analyses. Following sample preparation and serial dilutions, three dilutions of each sample were plated out in duplicates on nutrient agar using the pour plate and streak methods. Pure cultures of each observed microorganism were purified using sub-culturing techniques, then cultural, microscopic and biochemical characteristics were used for identification of specific isolates. A total of eighteen microorganisms namely Bacillus spp, Bacillus cereus, Bacillus subtilis, Bacillus megaterium, Bacillus mycoides, Lactobacillus spp, Leuconostic spp, Micrococcus spp, Klebsiella spp, Pseudomonas spp, Escherichia coli, Enterobacter spp, Azotobacter spp, Staphylococcus spp, Salmonella spp, Serratia spp, Citrobacter spp and Flavobacterium spp were isolated. The results of this study revealed that all organisms in amaranth were present in the analysed soil and irrigation water. Several pathogenic bacteria such as Escherichia coli and Salmonella spp were involved in the contamination of amaranth on the farm, and this is of a high potential health hazard to consumers. Contaminated irrigation water and soil were possibly the sources of contamination of amaranth growing on the field. Farmers should be educated on the risk involved in the use of contaminated water for irrigation.
