Dust in poultry confinement facilities were investigated for their fungi and mycotoxins contents. Concentrations of microfungiin the air of poultry confinement facilities were determined using air samplers, and fungal isolation from airby plate exposure. Settled dusts were investigated for their fungal load, types of fungi present and mycotoxins present.Microfungal load in settled dust and air of poultry confinements were found to be 3.5-42 x 106 cfu/g and 5-119 x105 cfu/m3 respectively. Fungi isolated from poultry confinements were: Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus,Aspergillus parasiticus, Aspergillus ochraceus Penicillium notatum, Mucor racemosus, Penicillium oxalicum, Trichodermaviride, Stachybotrys atra, Fusarium oxysporum, Candida albicans, Cryptococus neoformans and Saccharomyces cerevisae.Mycotoxins concentrations obtained from the analyses of sieved poultry dust were 21.32 + 2.35 ppb of aflatoxins,11.26 + 1.78 ppb of ochratoxins and 4.10 + 0.13 ppb of fumonisins. Aflatoxin concentrations and fungal loads in settleddust showed positive correlation with duration of dust deposition, but the former produced stronger association than thelatter (r = +0.991, P < 0.001 and r = +0.957, P < 0.02 respectively). Results obtained in this study indicate that poultrydust is rich in mirofungi and mycotoxins which could be of occupational health importance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
