The presence of ochratoxin A (OTA) in human blood has been reported for many countries, especially in Europe. However, so far no report exists concerning such a presence in Argentina. The aim of this study was to assess OTA concentration in human plasma in two different areas of Buenos Aires province. OTA was determined by high-performance liquid chromatography (HPLC) in 199 plasma samples from...

Grain products are a staple of diets worldwide and therefore, the ability to accurately and efficiently detect foodborne contaminants such as mycotoxins is of importance to everyone. Here we describe an indirect competitive fluid array fluoroimmunoassay to quantify the mycotoxins, fumonisin B1 and ochratoxin A. Both toxins were immobilized to the surface of microspheres using a variety of inter...

Ochratoxin A, a toxin of Aspergillus ochraceus, suppresses the immune response to sheep erythrocytes in BALB/c mice at doses as low as 0.005 microgram/kg of body weight. This effect is prevented by phenylalanine.

Received: 10 January, 2016 Accepted: 17 March, 2016 Published: 20 June, 2016 Gamma ray was applied to reduce mycotoxins, i.e. ochratoxin A (OTA) and aflatoxins B1, B2, G1 and G2 (AFB1, AFB2, AFG1 and AFG2) in black and white pepper. The aim of the this study was to evaluate the efficacy of gamma radiation for decontaminating ochratoxin) and aflatoxins residues in artificially contaminated black...

Mycotoxins are toxic secondary metabolites of fungi that contaminate a large variety of foods and have toxic effects on humans. The best protection against mycotoxins is to monitor their presence in food. This paper shows the screening results of mycotoxins present in 76 samples of different groups of grain foods. Samples of grain food were analyzed for contamination with aflatoxins, ochratoxin...

In February 2014, CDC's National Institute for Occupational Safety and Health received a request for a health hazard evaluation from a union representative in an office building. A female employee reported the onset of symptoms involving multiple organ systems upon returning to work after a prolonged absence. The employee searched the Internet for descriptions of symptoms matching hers, found a...

Background: This study intended to assess individual and combined adsorption potentials of three adsorbents (processed bentonite as an inorganic adsorbent, and cell walls of Saccharomyces cerevisiae and of the GG strain of Lactobacillus rhamnosus as organic adsorbents) for aflatoxin B1 and ochratoxin A under in vitro conditions. Methods: This study was conducted in Ferdowsi University of Mashh...
