Probst, C., Bandyopadhyay, R., Price, L. E., and Cotty, P. J. 2011. Identification of atoxigenic Aspergillus flavus isolates to reduce aflatoxin contamination of maize in Kenya. Plant Dis. 95:212-218. Aspergillus flavus has two morphotypes, the S strain and the L strain, that differ in aflatoxin-producing ability and other characteristics. Fungal communities on maize dominated by the S strain o...

Three-hundred and twenty 7-day-old Ross 308-strain broiler chickens were fed diets containing 0 or 125 ppb aflatoxin B 1 (AFB1) from 7 to 28 days of age. Sodium bentonite (0.5%), yeast (Saccharomyces cervisiae) 0.2%, hydrated sodium calcium aluminosilicate (HSCAS) (0.5%), ammonia (0.5%), formycine (0.1%), and toxiban (0.1%) were added to the basal diet, as fed basis to determine the effects of ...

The effects of increasing aflatoxin B1 concentration (0, 0.75, 1.5 mg/kg) on broilers with or without necrotic enteritis or virginiamycin were determined. In the 23-d study, 22 male Cobb 500 chicks per pen were allotted to 12 treatments (3 × 2 × 2 factorial arrangement) with 8 replications. Intestines of 5 birds per pen were examined for lesions on d 21. Birds were allowed to consume feed and w...

Understanding the source of Aspergillus flavus is required to manage aflatoxin contamination of maize (Zea mays L.). Studies assessed A. flavus propagules, Fusarium spp., and total fungi associated with Mississippi Delta soils. Soils from 12 and 15 sites were collected in 2000 and 2001, respectively. The propagule density of A. flavus ranged from log(10) 2.0 to 4.3 colony-forming units (cfu) g(...

A cohort of 18,244 mostly middle-aged (45-64 years) men residing in four small geographically defined areas of Shanghai was accrued between January 1986 and September 1989. In addition to an in-person interview regarding dietary and other past exposures, each subject donated a single void urine sample at recruitment so that the presence of aflatoxins in urine could be assessed. In addition, a 1...

Aflatoxin, a potent carcinogen, is produced by the fungus Aspergillus flavus Link: Fr. Drought, high temperatures, and insect damage contribute to increased levels of aflatoxin contamination in corn, Zea mays L. Plant resistance is widely considered a desirable method of reducing aflatoxin contamination. Germplasm lines with aflatoxin resistance have been developed. This investigation was under...

The content limit for allatoxin B1 in feedstuffs of the European Common Market Commission can result in the presence of aflatoxin in milk, Traces of aflatoxin have been found in milk, depending on the feedstuff used, feeding conditions and the season of the year. These results were confirmed by thin-layer chromatography, by chemical reactions and by fluorescence spectra. Metabolic investigation...

successful export of a commodity is closely dependent upon observing the related international standards. aflatoxin standard is an important index of pistachio import/export market. a lot of pistachio consignments are annually rejected because of being infected with aflatoxin. this results in export market's instability and fluctuations. the role of aflatoxin contammination in pistachio ma...

A method was developed for simultaneous quantitation of Aspergillus flavus/A. parasiticus and aflatoxins in peanuts. Peanut samples were ground with an equal weight of water in a vertical cutter mixer to produce a slurry. Separate subsamples were taken for dilution-plating to determine total colony forming units (CFU)/g of A. flavus/A. parasiticus and for liquid chromatographic analysis to dete...

Mycotoxins – General SCUDAMORE, K.A. and PATEL, S. 2000. Survey for aflatoxins, ochratoxin A, zearalenone and fumonisins in maize imported into the United Kingdom. Food Additives and Contaminants 17: 407–416. Raw maize as received at ports or at major maize mills in the UK were examined for aflatoxins B 1 , B 2 , G 1 and G 2 , ochratoxin A (OA), zearalenone (ZEA) and fumonisins B 1 , B 2 and B ...
