RT Report T1 Environmental Health Criteria 105: Selected Mycotoxins: Ochratoxins, Trichothecenes, Ergot A1 World Health Organization, K1 toxic substance K1 alkaloid K1 environmental health K1 chemical SN 92 4 157105 5 YR 1990 FD 1990 LK https://wedocs.unep.org/handle/20.500.11822/29486 UL https://wedocs.unep.org/handle/20.500.11822/29486 NO Ochratoxins are produced by several species of the fungal genera Aspergillus and Penicillium. These fungi are ubiquitous and the potential for the contamination of foodstuffs and animal feed is widespread. Ochratoxin A, the major compound has been found in a number of countries in Australasia, Europe, and North America. Ochratoxin formation by Aspergillus species appears to be Limited to conditions of high humidity and temperature, whereas at least some Penicilliurn species may produce ochra-toxin at temperatures as low as 5 °C.
