Abstract

The aim of this study is to determine the levels of deoxynivalenol (DON), HT-2 toxin (HT2), T-2 toxin (T2), and ochratoxin A (OTA) in bee products (bee pollen, propolis, honey and royal jelly) available in Turkey. In addition, exposure and health risk assessments were performed to identify the potential health risk of these mycotoxins. The mycotoxins were analyzed by high-performance liquid chromatography (HPLC) with a UV detector and positive samples were confirmed with liquid chromatography-tandem mass spectrometry (LC-MS/MS). The most common mycotoxins in all bee products were DON and T-2 toxin, with mean concentrations of 1.601 and 0.704 µg/per kg dry sample, respectively, followed by OTA and HT-2 toxin. It was determined that the mycotoxins taken as a result of consuming bee products in specified amounts do not pose a risk to health.

Occurrence, Toxicity, and Analysis of Major Mycotoxins in Food

Ahmad Alshannaq, Jae-Hyuk Yu (2017)

Mycotoxins are toxic secondary metabolites produced by certain filamentous fungi (molds). These low molecular weight compounds (usually less than 1000 Daltons) are naturally occurring and practically unavoidable. They can enter our food chain either directly from plant-based food components contaminated with mycotoxins or by indirect contamination from the growth of toxigenic fungi on food. Mycotoxins can accumulate in maturing corn, cereals, soybeans, sorghum, peanuts, and other food and feed crops in the field and in grain during transportation. Consumption of mycotoxin-contaminated food or feed can cause acute or chronic toxicity in human and animals. In addition to concerns over adverse effects from direct consumption of mycotoxin-contaminated foods and feeds, there is also public health concern over the potential ingestion of animal-derived food products, such as meat, milk, or eggs, containing residues or metabolites of mycotoxins. Members of three fungal genera, Aspergillus, Fusarium, and Penicillium, are the major mycotoxin producers. While over 300 mycotoxins have been identified, six (aflatoxins, trichothecenes, zearalenone, fumonisins, ochratoxins, and patulin) are regularly found in food, posing unpredictable and ongoing food safety problems worldwide. This review summarizes the toxicity of the six mycotoxins, foods commonly contaminated by one or more of them, and the current methods for detection and analysis of these mycotoxins.

Mycotoxins: occurrence, toxicology, and exposure assessment.

Leopoldo G. Sancho, Robert S Marin, V Sanchis-Alfonso … (2013)

Mycotoxins are abiotic hazards produced by certain fungi that can grow on a variety of crops. Consequently, their prevalence in plant raw materials may be relatively high. The concentration of mycotoxins in finished products is usually lower than in raw materials. In this review, occurrence and toxicology of the main mycotoxins are summarised. Furthermore, methodological approaches for exposure assessment are described. Existing exposure assessments, both through contamination and consumption data and biomarkers of exposure, for the main mycotoxins are also discussed. Copyright © 2013 Elsevier Ltd.
