Aflatoxin is a human health threat concern in many developing countries. This study examines Kenyan milk consumers’ behaviour toward aflatoxin by way of choice experiments. Further, willingness to pay for different types of milk and aflatoxin status awareness were assessed. Four attributes were selected to describe milk products: smell, colour, price and aflatoxin-free certification. Results in...

This work aimed to analyze the nutrient values, examine the biodeteriorating fungi biota, and analyze the mycotoxin contents of "Suya spices." Fungi with highest percentage occurrence on all the samples are Aspergillus niger, Aspergillus flavus, Aspergillus parasiticus, Aspergillus ochraceus, Fusarium sp., Rhizopus stolonifer, yeast, and Trichoderma koningii. Nutrient composition of the samples...

Lactating dairy goats were exposed to aflatoxin (100 and 200 ppb) and hydrated sodium calcium aluminosilicate at 1, 2, and 4% in two separate experiments. Naturally occurring low levels of aflatoxin M1 (.009 ppb) were found in the milk of the control diet, whereas there were no detectable levels of aflatoxin M1 in the milk of diets containing hydrated sodium calcium aluminosilicate in both expe...

Aflatoxins belong to a category of mycotoxins that have impacted mankind since the beginning organized cultivation. This toxin is produced by certain molds in food and feeds results adverse health effects both humans animals, as well economic barriers farmers countries. Therefore, this study aimed investigate current level aflatoxin awareness knowledge its contamination, preventive measures, im...

Eukaryotes have evolved highly conserved vesicle transport machinery to deliver proteins to the vacuole. In this study we show that the filamentous fungus Aspergillus parasiticus employs this delivery system to perform new cellular functions, the synthesis, compartmentalization, and export of aflatoxin; this secondary metabolite is one of the most potent naturally occurring carcinogens known. H...

Isolation of Apergillus flavus from groundnut and production of aflatoxin on rice. a method has been developed for the production of aflatoxin by growing Aspergillus flavus strain AJ on the solid substrate rice. Optimal yields, more than 1mg of aflatoxin B1 per gram of starting material, were obtained in 5 days at 28C.A crude product containing aflatoxin was isolated by HPLC (High Performance L...

Mice are resistant to aflatoxin hepatotoxicity, primarily due to high expression of glutathione S-transferases (GSTs), and in particular the GSTA3 subunit. Nuclear factor erythroid 2 related factor 2 (Nrf2) signaling, which controls a broad-based cytoprotective response, was activated either genetically or pharmacologically in an attempt to rescue GSTA3 knockout mice from aflatoxin genotoxicity...

The rapid detection of mycotoxin contamination in agricultural commodities is an area of research that requires more attention. The many companies buying hundreds of bushels of cereal grains daily, need to inspect their purchases immediately and to make a decision in minutes. Arising from this need to detect aflatoxin, we have developed two methods for rapid identification of aflatoxin in corn....

Aflatoxins are highly toxic carcinogens produced by several species in Aspergillus section Flavi. Strains of A. flavus that do not produce aflatoxins, called atoxigenic strains, have been used commercially in North America as tools for limiting aflatoxin contamination. A similar aflatoxin management strategy is being pursued in Nigeria. In the current study, loci across the 68 kb aflatoxin bios...
