Toxin Formation

The article presents the results of complex study of cotton-seed cake from the Republic of Tajikistan, including the determination of content of mycotoxins, the analysis of exposure to microscopic fungi and the assessment of the potential of their toxin formation. The ability to produce mycotoxins was established for 11 species of micromycetes belonging to the genus Aspergillus, Penicillium, Fusarium, Scop-ulariopsis, and Trichothecium. Alternariol, zearalenone, fu-monisins, aflatoxin B1, sterigmatocystin, ochratoxin A, citrinin and emodin were found in the composition of the cotton-seed cake. Prospects for further research and the practical significance of the results are discussed.

Modified Method

Abstract A collaborative study, in which 19 laboratories participated, was conducted on a modified method for the determination of aflatoxins in 2 copra samples, one naturally contaminated, and 4 samples of naturally contaminated copra meal. The sensitivity and precision of the modified method for aflatoxin B1 and total aflatoxins were comparable to the official methods for peanuts and peanut products. Aflatoxins B2, G1, and G2 were reported by most of the laboratories, but background interferences made quantitative measurement less reliable than for B1. The method as it presently stands is also applicable to the analysis of coconut. The method has been adopted as official first action; further study will be directed toward improved precision for analysis of aflatoxins B2, G1, and G2.
