Determination of aflatoxin risk components for in-shell Brazil nuts

A study was conducted on the risk from aflatoxins associated with the kernels and shells of Brazil nuts. Samples were collected from processing plants in Amazonia; Brazil. A total of 54 test samples (40 kg) were taken from 13 in-shell Brazil nut lots ready for market. Each in-shell sample was shelled and the kernels and […]

Aflatoxin B1 in post-harvest peanuts and dietary risk in China

To monitor the aflatoxin contamination status in raw peanuts and evaluate the effect on public health; 1040 samples were collected from four agro-ecological zones throughout 12 provinces from 2009 to 2010 in China and then analyzed for aflatoxin B1 (AFB1) levels using High Pressure Liquid Chromatography (HPLC) and immunoaffinity columns. The results revealed that AFB1 […]

Further mycotoxin effects from climate change

Climate change will affect mycotoxins in food. The 2007 Intergovernmental Panel on Climate Change report is reinterpreted herein to account for what may occur with mycotoxins. Warmer weather; heat waves; greater precipitation and drought will have various impacts; depending on which regions of the world and mycotoxin systems are considered. The humidity issues are more […]

Aflatoxin B1 Degradation by Bacillus subtilis UTBSP1 isolated from pistachio nuts of Iran

Pistachio nuts are among the commodities with the highest risk of aflatoxin contamination in Iran. Aflatoxin B1 (AFB1) is one of the most hazardous mycotoxins for humans and livestock. In nature; there are microorganisms which are capable of reducing aflatoxins contamination in food and feed products. In this study; Bacillus subtilis strain UTBSP1 was isolated […]

Contamination of Cyclopiazonic Acid in Dried Figs and Co-occurrence of Aflatoxin

Natural cyclopiazonic acid (CPA) and aflatoxin (AF) contamination were investigated in Aspergillus section Flavi positive dried fig samples collected from orchards after harvesting. Cyclopiazonic acid and AF were determined by thin-layer chromatography (TLC) and high performance liquid chromatography (HPLC); respectively. Cyclopiazonic acid was found in all samples of dried figs that contain AF. Cyclopiazonic acid […]

A high selective immunochromatographic assay for rapid detection of aflatoxin B

To solve the problem of low selectivity of current immunochromatographic assay (ICA) for aflatoxin B1 (AFB1) alone detection; a novel selective ICA was developed here. With very high selectivity; a new AFB1 monoclonal antibody (MAb) 3G1 was preparaed by immunizing Balb/c mice with aflatoxin B2a-BSA (AFB2a-BSA) rather than AFB1-BSA used in other reports and 3G1 […]

Key Roles of Vitamins A; C; and E in Aflatoxin B1-Induced Oxidative Stress.

Abstract: Aflatoxins (Aspergillus flavus toxins) are one of the natural toxic molecules which are produced by a group of fungi called Aspergillus. Foods and drinks contaminated with aflatoxins cause global health and environmental problems. Today in many developing countries; these toxins are leading cause of some liver cancers and serious gastrointestinal problems. Aflatoxins; which are […]

Detection of contaminated hazelnuts and ground red chili pepper flakes by multispectral imaging

Mycotoxins are the toxic metabolites of certain filamentous fungi and have been demonstrated to cause various health problems in humans; including immunosuppression and cancer. Among them; the aflatoxins have received greater attention because they are potent carcinogens and are responsible for many human deaths per annum; mostly in non-industrialized countries. Various regulatory agencies have enforced […]
