Mycotoxins are toxic secondary metabolites produced by fungi when they colonies the foodstuffs. These potent toxins having severe health consequences in people, being mutagenic, teratogenic, and carcinogenic. In agricultural commodities, contamination of mycotoxins is more prevalent. Several can produce on products during harvest or postharvest, have significant adverse effects both animal huma...

HINTIKKA, E.L. and NIKULIN, M. 1998. Airborne mycotoxins in agricultural and indoor environments. Indoor Air – International Journal of Indoor Air Quality and Climate Supp. 4: 66–70. This overview with 33 references discusses the increasing reports of inhalation exposure to mycotoxins in agricultural environments and in water damaged buildings with mould problems. There is evidence that inhalat...

Mycotoxins are secondary metabolites produced by certain filamentous microscopic fungi, which occur naturally in the environment and may persist in animal feed. A mycotoxin contaminated diet may lead to feed refusal, poor feed conversion, diminished body weight gain and causes pathological effects associated with gross and histological changes, which are responsible for great economical losses....

In order to explore the biochemical scope of ochratoxin A-producing penicillia, we screened 48 Penicillium verrucosum isolates for the production of secondary metabolites. Fungal metabolites were analyzed by high-pressure liquid or gas chromatography coupled to diode array detection or mass spectrometry. The following metabolites were identified: ochratoxins A and B, citrinin, verrucolones, ver...

Contamination by microscopic fungi and mycotoxins in high moisture corn (HMC) silages conserved by chemical additives was investigated. The samples were examined for the concentration and identification of microscopic fungi able to grow on Malt and Czapek-Dox agar and for mycotoxins content (deoxynivalenol, T-2 toxin, zearalenone and total aflatoxins, fumonisins, ochratoxins) by direct competit...

Ochratoxin A is a toxic and carcinogenic fungal secondary metabolite; its presence in foods is increasingly regulated. Various fungi are known to produce ochratoxins, but it is not known which species produce ochratoxins consistently and which species cause ochratoxin contamination of various crops. We isolated fungi in the Aspergillus ochraceus group (section Circumdati) and Aspergillus alliac...
