The highest mean ± SD fungal counts were 3.23 x 103 ± 0.03 CFU/g, 3.07 x 104 ± 0.01 CFU/g and 8.67 x 102 ± 0.13 CFU/ml for vegetable, soil, and water samples, respectively. A total of 32 fungal strains isolated were presumptively identified as &lt;em&gt;Aspergillus&lt;/em&gt; sp. (50%), &lt;em&gt;Fusarium&lt;/em&gt; sp. (6.25%), &lt;em&gt;Chrysonilia sitophila&lt;/em&gt; (3.13%), &lt;em&gt;Acremonium&lt;/em&gt; sp. (6.25%), &lt;em&gt;Mucor&lt;/em&gt; sp. (12.5%), and &lt;em&gt;Rhizopus&lt;/em&gt; sp. (21.87%). The molecular characterization of &lt;em&gt;Aspergillus&lt;/em&gt; strains revealed &lt;em&gt;Aspergillus aculeatus&lt;/em&gt;, &lt;em&gt;Aspergillus fijiensis&lt;/em&gt;, &lt;em&gt;Aspergillus flavus&lt;/em&gt;, &lt;em&gt;Aspergillus japonicas&lt;/em&gt;, and &lt;em&gt;Aspergillus niger&lt;/em&gt;. All the 16 &lt;em&gt;Aspergillus&lt;/em&gt; species showed aflatoxin B1 production with &lt;em&gt;Aspergillus japonicus&lt;/em&gt; (AWF27) isolated from the irrigation water having the highest concentration (106 µg/kg) and &lt;em&gt;Aspergillus fijiensis&lt;/em&gt; (ASF6) isolated from soil having the lowest concentration (93 µg/kg). The work revealed the potential for human exposure to mycotoxin through contaminated fresh vegetables. Concerted effort is required, especially in developing countries for cultivation of fresh vegetables in hygienic environment with clean irrigation water.&lt;/p&gt;
