Insight in the effect of fungal growth temperature on toxigenicity of A. radicina and A. alternata isolates grown on PDA, rice grains, and carrot discs

Testing Alternaria spp. for their toxigenicity at 1, 10 and 20 degrees Celsius on PDA, rice and carrot root discs revealed that although the fungi were capable of producing toxins on PDA and rice, none were detected on carrot until 28 days of incubation. This indicates that a relatively short term storage of carrot at low temperature seems to be not hazardous for consumers, even in case of contamination with any of the two Alternaria spp. tested.
