Aflatoxin contamination and its relationship to storage length in stored maize and rice in Liaoning Province, northeastern China, was investigated. Aflatoxins in 110 samples collected from an area of 14.68million km covering storage length from 1 yr to over 10 yr were determined by high-performance liquid chromatography with fluorescence detection. The results showed that almost all samples col...

BACKGROUND Aflatoxin contamination of food and feed stuff is a serious health problem and significant economic concerns. In the present study, the inhibitory effect of Candida parapsilosis IP1698 on mycelial growth and aflatoxin production in aflatoxigenic strains of Aspergillus species was investigated. METHODS Mycelial growth inhibitions of nine strains of aflatoxigenic and non-aflatoxigeni...

Aflatoxin contamination of nuts is an increasing concern to the consumer's health. Portugal is a big producer of almonds, but there is no scientific knowledge on the safety of those nuts, in terms of mycotoxins. The aim of this paper was to study the incidence of aflatoxigenic fungi and aflatoxin contamination of 21 samples of Portuguese almonds, and its evolution throughout the various stages ...

Mycotoxin (aflatoxins) contamination of peanuts is a great concern for human health. A total of 72 samples of unripe, roasted, and salty peanuts were collected randomly from Pothohar plateau of Pakistan for the assessment of aflatoxin. Samples were dried, ground and extracted by acetonitrile (84%). The filtered extracts were cleaned up by MycoSep-226 and analyzed by high performance liquid chro...

A bacterium was isolated from the soil of dumping ground for cattle yard waste by enrichment culture containing aflatoxin B1. This bacterium was closely related to Bacillus firmus that was found to be a non-pathogenic bacterium. The minimum inhibitory concentration of aflatoxin B1 to the bacterium was found to be 80 microg ml(-1) as measured by total viable count and soluble protein content met...

The aim of the present investigation was to check natural aflatoxin contamination and aflatoxigenic potential of Aspergillus flavus strains isolated from chilgoza pine nuts. Fifty eight samples of chilgoza pine nuts, randomly purchased from retail shops and local markets of different locations of Jammu, were subjected to mycological analysis for isolation of Aspergillus flavus isolates using st...

AFLATOXIN B1, a carcinogenic metabolite of the fungus Aspergillus flavus, is acutely toxic to a number of species, including rats. Male rats (LD50 7-2 mg./kg.) are more susceptible to the acute oral effects of aflatoxin than are females (LD50 17.9 mg./kg.) (Butler, 1964). Aflatoxin B1 is metabolised to aflatoxin M1 which is present in the blood and urine of dosed rats (Butler and Clifford, 1965...

Seeds of aflatoxin-resistant and aflatoxin-susceptible maize lines were inoculated with conidia of aflatoxin-producing Aspergillus flavus or A. parasiticus isolates or isogenic non-producing mutants. Conidia were recovered from resistant maize seed after seven days in significantly lower amounts for aflatoxin-producing A. flavus and A. parasiticus strains than for isogenic mutants incapable of ...

Aflatoxin is a mycotoxin and a secondary metabolite, and the most potent known liver carcinogen that contaminates several important crops, and represents a significant threat to public health and the economy. Available approaches reported thus far have been insufficient to eliminate this threat, and therefore provide the rational to explore novel methods for preventing aflatoxin accumulation in...
