Occurrence of Fungi on Indoor Food Grains Storage House

Abstract Microorganism which is including fungi, algae, bacteria virus and organic dust present in air can cause several allergic infections. To study was conducted in 5 different as of indoor food storage house in Bholad to analyze the composition and intensity of fungal spore using petri-plate method. Fungal spores are present in order 1.7x10 to 4.2x10 .Fungal spore identified in there are the most dominating species are Aspergillus. Rhizopus, Mucor, Alternaria, Cladosporium, Trichoderma and Fusarium. The presence of airborne microorganisms, particularly fungi, in food grain storage facilities poses significant health risks to workers due to prolonged exposure to grain dust and mycotoxins. This study investigated the occurrence, diversity, and seasonal variation of fungal species in five indoor food storage houses located in Bhalod, Jalgaon District (M.S.), using the Petri-plate exposure method over a two-year period (June 2023–May 2025). A total of six fungal species belonging to seven genera were identified, with Aspergillus, Rhizopus, Mucor, Alternaria, Cladosporium, Trichoderma, and Fusarium being the most dominant. The results revealed that fungal spore concentrations were significantly higher during the winter season compared to summer, with Aspergillus flavus and Alternaria alternata showing the highest prevalence. The study highlights the strong seasonal influence on fungal distribution and underlines the potential occupational health risks, including asthma and respiratory allergies, among workers exposed to contaminated storage environments. Effective hygiene practices and monitoring of fungal load are recommended to minimize health hazards in grain storage facilities.
