Occurrence of aflatoxin B1 in natural products
The media claims for the consumption of natural resource-based food have gradually increased in both developing and developed countries. The interest in the safety of these products is partially due to the possible presence of toxigenic fungi acting as mycotoxin producers, such as aflatoxins produced during the secondary metabolism of Aspergillus flavus, A. parasiticus and A. nomius. Aflatoxins...
متن کاملOccurrence of Aflatoxin M1 in Dairy Products
Aflatoxin M1 (AFM1) is a major metabolite of aflatoxin B1 (AFB1), which is formed when animals ingest feed contaminated with aflatoxin B1. The AFB1, once ingested by the animal, is rapidly absorbed by the gastrointestinal tract and is transformed into the metabolite AFM1, which appears in the blood after 15 minutes and is then secreted in the milk by the mammary gland (Van Egmond, 1989; Battaco...
متن کاملComparative binding and sequence interaction specificities of aflatoxin B1, aflatoxicol, aflatoxin M1, and aflatoxicol M1 with purified DNA.
The covalent binding of the activated forms of several aflatoxins to N-7 of guanine residues on purified DNA has been studied. The aflatoxins include aflatoxin B1 (AFB1) and two human metabolites, aflatoxicol and aflatoxin M1, along with aflatoxicol M1, a rabbit and trout metabolite. DNA binding studies using tritiated [3H]aflatoxins indicate that equimolar solutions of each aflatoxin upon acti...
متن کاملOccurrence of Aflatoxin M1 in Raw and Pasteurized Milk Produced in Rafsanjan, Iran
Introduction: Aflatoxins, known as causative factors of hepatic and extra-hepatic carcinogenesis within humans, are extremely teratogenic, mutagenic, toxic, and carcinogenic compounds. Materials & Methods: This study was undertaken to determine the occurrence of aflatoxin M1 (AFM1) in 40 raw milk and 47 pasteurized milk samples collected during spring and winter. In order to analyze the samp...
متن کاملOccurrence of Aflatoxin M1 in Pasteurized and Traditional Cheese Marketed in Southern Khorasan, Iran
Background: Aflatoxin M1 (AFM1) is a toxic and carcinogenic mycotoxin which after presence in milk and dairy products such as cheese and butter could make them as contaminated food. The main objective of this study was to evaluate the concentration of AFM1 in pasteurized and traditional cheese marketed in Southern Khorasan, from December 2011 to January 2012. Methods: A total of 102 cheese sam...
