Twenty-three isolates of fungi, representing 13 thermophilic and thermotolerant species, were bioassayed for toxigenicity to brine shrimp, chicken embryos, and rats. Thirteen isolates representing nine genera were highly toxic to at least two of the three systems. Seven additional isolates of five genera were slightly toxic.

Numerous plant species, which are main components of various mixtures used in animal nutrition, can be contaminated by mycotoxins created by large number of pathogenic and toxigenic fungi (moulds). From the aspect of animal nutrition, most important are cereals and oil crops (in form of meals) because they constitute the highest share in preparation of animal food, and on the other hand, they a...

Mycotoxins are unavoidable contaminants of food grains, feeds, medicinal herbs, and spices, posing as health threat to animals and humans. The objective of this study was to screen medicinal herbs and spices for fungi and mycotoxin contamination and evaluate their safety. Sixty-three samples were examined for fungal contamination and fungal load determined using standard microbiological method....

results aflatoxins have been found in many food products in iran. conclusions it is necessary to detect aflatoxins in foods and food products as early as possible, before they enter human or animal bodies. there is a high consumption of milk and dairy products in iran, and the proper management of animal foods can help to decrease the aflatoxins in milk. evidence acquisition in consideration of...

Aspergillus flavus is a very important toxigenic fungus that produces aflatoxins, a group of extremely toxic substances to man and animals. Toxigenic fungi can grow in feed crops, such as maize, peanuts, and soybeans, being thus of high concern for public health. There are toxigenic and non-toxigenic A. flavus variants, but the necessary conditions for expressing the toxigenic potential are not...

The present work was carried out to study the mycobiota of cocoa beans from farm to chocolate. Four hundred and ninety-four samples were analyzed at various stages of cocoa processing: (i) primary stage at the farm (fermentation, drying, and storage), (ii) secondary stage at processing (testa, nibs, liquor, butter, cake and powder) and (iii) the final chocolate product (dark, milk, white and po...

The increase in the consumption of natural drugs have made their use a Public Health problem due to the possibility of access to products without adequate conditions of use. The concern with the quality of the natural products is due to the potential fungal contamination and the risk of the presence of mycotoxins. Ninety-one samples of medicinal plants were evaluated for the fungal contaminatio...
