Innovative Nutritious Biscuits Limit Aflatoxin Contamination

Aflatoxin Contamination of Bt Cottonseed

Transgenic Bt cotton may have reduced susceptibility to aflatoxin contamination as a result of pink bollworm resistance. During 1995 and 1996, Bt cottonseed from several commercial fields in Arizona contained aflatoxin levels unacceptable for dairy use. Comparison of cottonseed with and without BGYF (bright-green-yellow fluorescence) from one highly contaminated (>6,000 ppb aflatoxin Bj) Bt see...

Influences of climate on aflatoxin producing fungi and aflatoxin contamination.

Aflatoxins are potent mycotoxins that cause developmental and immune system suppression, cancer, and death. As a result of regulations intended to reduce human exposure, crop contamination with aflatoxins causes significant economic loss for producers, marketers, and processors of diverse susceptible crops. Aflatoxin contamination occurs when specific fungi in the genus Aspergillus infect crops...

Etiology and Management of Aflatoxin Contamination

Aflatoxins are potent poisons that contaminate crops in warm regions worldwide and reduce health and economic welfare in several portions of Africa. Crops are contaminated in two phases: First, Aspergillus species infect crops during development; and second, after maturation contamination builds during exposure to warm humid conditions. Identification of the exact fungi causing contamination ca...

Aflatoxin Contamination and Research in China

Aflatoxins(AF) are highly poisonous secondary metabolites produced by Aspergillus flavus and Aspergillus parasiticus. They have been found in moldy human food and animal feeds and have been implicated in numerous animal disorders. A. parasiticus produces four major aflatoxins: B1 , B2 , G1 and G2 , while AFB1 is the most toxic in the group and the toxicity is in the order of B1 > G1 > B2 > G2. ...
