ABSTRACT

 

Bioaerosols which include bacteria, fungi, virus and organic dust present in the air can cause several allergic reactions. A study was conducted in five different areas of food godowns in Visakhapatnam (India) to analyze the composition and intensity of bacterial and fungal spores using gravity Petri-plate method. The bacteria were present in the order of 1.8x102 to 5.3x106. Fungal spores identified in these areas were 1.7x103 to 4.2x106. The most dominating species are Mucor, Rhizopus, Aspergillus, Penicillum, Alternaria, Cladosporium, Trichoderma, Fusarium, Pseudomonas, Proteus vulgari and Enterobacter aerogenes. Strains of Aspergillus producing as high as 1927.3 μg/kg aflatoxin.
