Separation of mycotoxin-containing sources in grain dust and determination of their mycotoxin potential.
Two distinct reservoirs of mycotoxins exist in fungal-infected cereal grains--the fungal spores and the spore-free mycelium-substrate matrix. Many fungal spores are of respirable size and the mycelium-substrate matrix can be pulverized to form particles of respirable size during routine handling of grain. In order to determine the contribution of each source to the level of mycotoxin contaminat...
متن کاملFood Safety, Toxicology and Utilization of Mycotoxin-contaminated Grain
Cereal crop plants are colonized by many fungal species such as Aspergillus ochraceus and Penicillium verrucosum, which produce ochratoxins, and Fusarium graminearum, which produces trichothecene mycotoxins. A multiplex real-time PCR method using TaqMan probes was developed to simultaneously detect and quantify trichothecene producing Fusarium species and ochratoxin A producing Penicillium and ...
متن کاملProtocols for surveys, sampling, post-collection handling, and analysis of grain samples involved in mycotoxin problems.
This report examines and summarizes current knowledge regarding mycotoxin surveys, sampling techniques, conditions conducive to post-collection production of mycotoxins in grain samples, and analytical methods for mycotoxin analysis. Priority attention is given to samples of corn suspected of containing aflatoxin. The report includes recommendations where deems appropriate by the Ad Hoc Work Gr...
متن کاملFactors determining accumulation of mycotoxin producers in cereal grain during harvesting.
During the meteorologically contrasting period of 2003-2005, the contamination of winter wheat, malt barley and fodder barley grain with micromycetes during grain harvesting and preparation for storage was investigated. Micromycetes of over 70 species ascribed to 16 genera were isolated and identified, the density of their populations in grain was determined. Micromycetes with a population dens...
متن کاملInfluence of Temperature and Water Activity on Deleterious Fungi and Mycotoxin Production during Grain Storage
Cereal grains are the most important food source for humans. As the global population continues to grow exponentially, the need for the enhanced yield and minimal loss of agricultural crops, mainly cereal grains, is increasing. In general, harvested grains are stored for specific time periods to guarantee their continuous supply throughout the year. During storage, economic losses due to reduct...
