the aim of this study was to evaluate aflatoxin m1 (afm1) contamination in pasteurized milk samples in mashhad, iran. one hundred and ten milk samples from different supermarkets were collected during three months in spring and investigated by enzyme linked immuno sorbent assay (elisa). afm1 was found in 100% of the milk samples. about 5.4% of the samples contained afm1 greater than the maximum...

This research investigated the optimal conditions of heat and chemical treatment for elimination aflatoxin. NaOH showed highest inhibition percentage (75.44%) Aspergillus flavus growth that was isolated from lowgrade maize. Low-grade maize contaminated with A. treated by varying three factors in levels: concentration (0, 2.5 5% w/v), temperature (25, 50 75°C) time (24, 48 72 h). Aflatoxin remov...

The pre-harvest biocontrol approach currently used includes laboratory inoculations using non-aflatoxigenic strains of Aspergillus flavus. This strategy effectively suppresses the indigenous aflatoxigenic and reduces aflatoxin accumulation in sweetcorn. current vitro study’s main objective is to determine diametric growth rates both Aflatoxin (AF)+ AF− improve understanding competitive relation...

In order to evaluate pistachio contamination to Aspergillus flavus in Semnan province; samples of pistachio kernels were collected from the last processing pistachio stage in traditional and semi-mechanized processing plants in 2010. They were examined for the presence A. flavus fungi. The samples were cultured on AFPA media. All plate were incubated for 3 to 7 days. At the end of incubation pe...

Background Mycotoxins are natural toxins, produced by several fungal species and are associated with morbidity or even mortality in animals, plants, and humans. In this study, 120 samples of herbs and spices in both bulk and packaged forms were prepared in order to measure aflatoxin level in different regions of Iran. Methods The aflatoxin was extracted during Mar to May 2015, using 80% metha...

BACKGROUND AND PURPOSE Aflatoxin M1, in milk and dairy products, is classified by the International Agency for Research on Cancer as human carcinogens (class 2B). The aim of this study was to evaluate aflatoxin M1 contamination level in dairy products from Iranshahr city, Iran, using ELISA technique. MATERIALS AND METHODS In our study, 87 samples of milk, white cheese, yoghurt, and butter wer...

BACKGROUND Aflatoxins are the most common mycotoxins that contaminate crops. They are produced by fungi such as Aspergillus flavus and Aspergillus parasiticus. Wheat (Tricitumaestivum) is one of the most important staple foods used in Iran, and the environmental conditions in the north of Iran are favorable to fungal growth. This study was designed in order to determine the aflatoxin concentrat...

The objective of this study was to examine the relationship between fluorescence emissions of corn kernels inoculated with Aspergillus flavus and aflatoxin contamination levels within the kernels. Aflatoxin contamination in corn has been a long-standing problem plaguing the grain industry with potentially devastating consequences to corn growers. In this study, aflatoxin-contaminated corn kerne...

BACKGROUND Aflatoxin, a potent fungal toxin, contaminates 25% of crops worldwide. Since 2004, 477 aflatoxin poisonings associated with eating contaminated maize have been documented in Eastern Kenya, with a case-fatality rate of 40%. OBJECTIVE We characterized maize aflatoxin contamination during the high-risk season (April-June) after the major harvests in 2005, 2006 (aflatoxicosis outbreak ...

the aim of this study was to evaluate the utility of a proficiency testing program among limited number of local laboratories as an alternative to the iupac/citac guide on proficiency testing with a limited number of participants, specially where international schemes are not accessible. as a sample scheme we planned to determine aflatoxins (b1, g1, b2, g2, total) in iranian pistachio matrix. a...
