“…At a later date, when grain from West Siberia was analyzed with ELISA, the researchers noted the wide occurrence of this pathogen and a significant T-2-toxin content [37,38]. In all likelihood, the environmental conditions of this region contribute to the existence and spread of F. sporotrichioides .…”

“…In all likelihood, the environmental conditions of this region contribute to the existence and spread of F. sporotrichioides . Indeed, a study of batches of wheat, barley, and oats harvested in 1995–2001 in the Ural region and in West Siberia using ELISA found T-2 toxin, on average, in 36.3% (5.1–69.4%) and 37.7% (5.9–86.7%) of the grain samples, respectively [38]. However, high levels of contamination exceeding the maximum allowable level were found in 2–3% of the analyzed samples in each region.…”

Wheat grains collected in three regions of Russia—Volga, Ural, and West Siberia—were analyzed for triangulation of methods in analysis of toxigenic Fusarium species. The presence of fungi and quantitative content of their biomass were detected by using various analytical methods, including a mycological and immunochemical methods, and quantitative PCR. Additionally, an enzyme-linked immunosorbent assay and high-performance liquid chromatography with tandem mass spectrometry were applied for determination of mycotoxins. Regional differences were found regarding the contamination of wheat grain by Fusarium fungi and their toxins. The most important observation was the detection of F. graminearum in the Ural and West Siberian regions, where this pathogen had not been found previously. A maximum damaged grains by F. graminearum and F. sporotrichioides was found in the grain samples from West Siberia. The DNA of F. graminearum was detected in 19.2% and DNA of F. sporotrichioides was found in 84.1% of the analyzed grain samples. The amount of Fusarium antigens in the grain samples from the West Siberian region was 7–8 times higher than in the grain samples from the other two regions. Significant contamination of the grain with deoxynivalenol and T-2/HT-2 toxins (maximum contents were 2239 ppb and 199 ppb, respectively) was detected in the West Siberian region.

“…Several surveys of mycotoxin contamination of grain in the Southern European region of Russia have been conducted [3,4]. In Krasnodar Territory in 2002-2003, grain was mainly contaminated by the T-2 toxin (85.0%) and was less often contaminated by DON (8.3%) and ZEN (0.7%).…”

Microbiological quality of grain cultivated in the North Caucasus region in 2019

et al. 2020

The microbiological quality of 23 grain samples of wheat and barley harvested in the North Caucasus in 2019 was analysed on the basis of the percentage of grains infected by fungi and the amounts of trichothecene-producing Fusarium DNA and Alternaria DNA. The mycotoxins produced by these fungi were also determined. Alternaria and Fusarium fungi were the predominant fungi in the mycobiota of grain, accounting for at 93% and 14% of the observed fungi, respectively. Alternariol produced by Alternaria fungi was detected in 65% of samples, and its content (11-675 ppb) was positively correlated with the abundance of fungi of section Alternaria in grain. F. langsethiae was found in wheat grain from the Chechen Republic for the first time. The T-2 toxin produced by this fungus was found in 25% of samples, and its content in one barley grain reached 650 ppb, which exceeded the permitted level for this mycotoxin. The mycotoxins deoxynivalenol and zearalenone, which are mainly produced by F. graminearum, were also identified in 13% of the grain samples. The positive correlation between the amounts of both these mycotoxins and the DNA of Tri-Fusarium was established.

“…Сырье растительного происхождения в рецептах отечественных комбикормов представлено в основном пшеничной, ячменной и кукурузной мукой, отрубями, а также подсолнечным жмыхом и шротом (14,16,17). Для зерна, предназначенного на кормовые цели, характерна контаминация фузариотоксинами с обширной встречаемостью Т-2 токсина (Т-2) и дезоксиниваленола (ДОН), иногда совместно с зеараленоном (ЗЕН); в зерне кукурузы часто обнаруживается фумонизин В1 (ФУМ В1) (21)(22)(23)(24)(25). Кроме того, установлена очаговая загрязненность зерна охратоксином А (ОА) (26), а в зерне пшеницы, кукурузы и в кормовой продукции из переработанных семян подсолнечника выявлены частые случаи совместного обнаружения ОА и цитринина (27,28).…”

“…In recent years, we have received convincing evidence that the group of the most likely contaminants of raw ingredients -wheat, barley and corn flour, bran, sunflower cake and meal -includes T-2 toxin, deoxynivalenol, fumonisins of group B and zearalenone, related to fusariotoxins, as well as alternariol, ochratoxin A, citrinin, cyclopiazonic acid, mycophenolic acid and emodin (G.P. Kononenko et al, 2018Kononenko et al, , 2019. Analysis of world data on experimental mycotoxicoses of different age groups of common carp (Cyprinus carpio), channel catfish (Ictalurus punctatus), white Amur (Ctenopharyngodon idellus), Nile tilapia (Oreochromis niloticus), rainbow trout (Oncorhynchus mykiss), Atlantic salmon (Salma salar), shows that fusariotoxins should be considered as key risk factors and efforts should continue to refine their safe thresholds.…”
