Increased aflatoxin contamination in corn by the fungus Aspergillus flavus is associated with frequent periods of drought and heat stress during the reproductive stages of the plants. The objective of this study was to evaluate the relationship between aflatoxin contamination and physiological responses of corn plants under drought and heat stress. The study was conducted in Stoneville, MS, USA...

nowadays, the separation of pistachios which seem to have aflatoxin is done according to their organoleptic physical qualities like color and etc. as these methods are not  fully practical, and there is always a possibility of error and also the conditions like the wrong time harvest, the transportation of picked pistachios, the delay on the processing cause some contaminations in pistachios wh...

A method has been developed to determine the presence of aflatoxin B1 in the urine of animals (including humans) by utilizing commercial immunochemical kits that can be used in the field. Urine is treated with diatomaceous earth and filtered to clarify the sample; 2-3 ppb aflatoxin B1, corresponding to about 300 ppb in the ingested feed/food, can be detected in the filtered urine without furthe...

The levels of aflatoxin (AFT) and ochratoxin (OCT) were assessed at different seasons in raw materials, feed manufacture processing stages, animal feeds mills Korea implementing the hazard analysis critical control point (HACCP) system. Two hundred samples collected all four from five HACCP system examined for AFT OCT contents. analysed by using HPLC method to provide information on material pr...

The distribution of aflatoxin concentration has been measured by sampling 19 process streams ranging from 1 to 1000 nuts/sample. The 19 streams comprise substantially the entire sorted product of one producer for crop year 1992. Similar results were obtained by another producer for 1993. The fraction of total aflatoxin accounted for by each process stream was computed. It was concluded that 90%...

Aflatoxin contamination is a major economic and food safety concern for the peanut industry that largely could be mitigated by genetic resistance. To screen peanut for aflatoxin resistance, ten genotypes were infected with a green fluorescent protein (GFP)-expressing Aspergillus flavus strain. Percentages of fungal infected area and fungal GFP signal intensity were documented by visual ratings ...

Background & Aims of the Study : Consumption of honey has remarkably increased in the last years all over the world. Factors such as plant species, environmental, processing, and storing condition are affecting honey quality. The purpose of this study was to evaluation of Hygienic quality of honey samples produced from Qazvin province. Materials and Methods: 34 fresh honey Samples were obta...

Aflatoxins are toxins which are usually produced by a kind of Aspergillus fungus named Flavus, Parasiticus, and Numius. There are 18 kinds of Aflatoxins have been discovered by scientists and Aflatoxin B1 is the most toxic and carcinogenic. Taking aflatoxins present in food causes lots of diseases like liver diseases, alcoholic liver, mutagenesis, and malformation in animals. It also has some o...

The potent mycotoxin aflatoxin B1 is a secondary metabolite of Aspergillus fungi that grow, on a variety of food and feed commodities at any stage during growth, harvest, storage and transportation. The occurrence of aflatoxin contamination is global, with severe problems especially prevalent in developing countries. In present study, corn samples were contaminated with aflatoxin B1 in the conc...
