Despite consented efforts in prevention, mycotoxins remain a problem of human health concern in several parts of the world including developed countries. Within the same range of toxins concentrations in the blood some people develop a disease while others do not. Could this inequality in front of mycotoxins effects be explained by environment factors and/or genetic predisposition? Among recent...

Aspergillus section Circumdati or the Aspergillus ochraceus group, includes species with rough walled stipes, biseriate conidial heads, yellow to ochre conidia and sclerotia that do not turn black. Several species are able to produce mycotoxins including ochratoxins, penicillic acids, and xanthomegnins. Some species also produce drug lead candidates such as the notoamides. A polyphasic approach...

abstract: ochratoxin a (ota) continues to attract global attention concerning the hazard and impact on both human and animals based on its toxicity and occurrence. the international agency for research on cancer (iarc) classifies it as possible carcinogen to human (group 2b). a total of 98 samples of dried fruits consisting of coconut, sour cherry, slices of peaches, quinces, and pineapple from...

SCOPE In this study, human exposure to the mycotoxin ochratoxin A (OTA) and its thermal degradation product 2'R-ochratoxin A (2'R-OTA, previously named as 14R-Ochratoxin A [22]) through coffee consumption was assessed. LC-MS/MS and the dried blood spot (DBS) technique were used for the analysis of blood samples from coffee and noncoffee drinkers (n = 50), and food frequency questionnaires were ...

Mycotoxin contamination in agro-food systems has been a serious concern over the last few decades in China, where the Ministry of Health has set maximum limits for mycotoxins in different agro-products. Overall survey data show that aflatoxin contamination in infant cereals, edible oils, raw milk, ginger and its related products are far below Chinese regulatory limits. The absence of aflatoxin ...

Ochratoxin A (OA) is a toxin that contains an isocoumarin moiety linked by a peptide bond to phenylalanine. It is produced by certain Penicillium (mainly P. verrucosum) and Aspergillus (mainly A. alutaceus) species of storage fungi. Total amounts of OA and other related toxins produced by these fungi are influenced by many factors. Several forms of OA have been discovered, some of which are hig...

Contamination feedstuffs with fungi or their metabolites toxins poses considerable hazard to public health and animal welfare. The information on mycotoxins identified from a variety of feedstuff in 2021 (soyabean, maize, fish meals, poultry pellets) was retrieved archive papers documented the Centre Standardization Quality Control/Department Agriculture. A total 1325 samples were examined by t...

Olsson, J. 2000. Modem methods in cereal grain mycology. Doctor's dissertation. ISSN 1401-6249, ISBN 91-576-5792-0. A simple rapid DNA extraction method, equally suitable for spores and mycelia is proposed. Heating samples in NaOH and SDS provides DNA of high purity, suitable for Polymerase Chain Reaction (PCR) analysis. For Penicillium roqueforti the detection limit was 6 x lo3 conidia and 1 m...
