Abstract

Fusarium fungi play an important role as pathogens of cereals in Romania. The areas mostly affected are western, northern and central parts of the country as they are characterized by weather conditions favorable to the mycotoxin development. Furthermore, the wheat/maize rotation has become fairly common during the last years, thus contributing to the increasing risks of Fusarium infestation [1]. Investigations on wheat and maize contamination with trichothecene toxins were carried out in western Romania. Nothing is known about the situation in cereals from other parts of the country and about the trichothecene contents in bread and pasta [2]. A total of 88 samples was taken at random in August and September 2006 in central Transylvania and western Romania, consisting of wheat (n = 42), bread and rolls (n = 32) as well as pasta (n = 14). Wheat was obtained from Farmers and a mill in the counties Alba, Cluj and Timis, other samples were collected in supermarkets and bakeries in Cluj-Napoca. 13 trichothecene toxins of the B-type as well as of the A-type were analysed by GC/MS [3] alter solid-phase extraction. Detection limits varied between 2 and 20µg/kg. In wheat the toxins nivalenol, deoxynivalenol (DON), 15-acetyldeoxynivalenol (15-ADON), 4-,15-diacetoxyscirpenol, HT-2 and T2 toxin were detected in 1, 38, 15, 1, 21 and 1 sample, respectively. In bakery products DON, HT-2 and T.-2 toxin and in noodles DON were found. The maximum concentrations of DON in wheat, bakery products and pasta were at 3 395, 352 and 35 µg/kg, respectively. These results prove contamination of trichothecenes in wheat and wheat-based foodstuffs in the central areas of Transylvania as well as in western Romania.
