Dietary items supply in retail shops are routed through a number of steps and storage processes. The middle men involved in between producer and consumer, are not sensitive towards to maintain appropriate conditions during storage and transportation, leading to spoilages. Some of these spoilages are toxic in nature. Growth of toxic Fungi is one such alarming infestation, which is rampant not only during post harvest conditions but even during pre harvest condition. To determine the level of fungal toxicity, samples were collected from retail shops. Present study is confined to Aspergillus group. Aflatoxins represent a group of toxic mold metabolites that are not only toxic but a proved carcinogen, mutagen, and teratogen as well. The study provides indirect evidences for many of the human ailments and emphasizes on solar energy drier and space heating mechanism to control it.
