“…Собранные нами данные из литературы свидетельствуют о том, что эти микотоксины не представляют никакой очевидной биохимической важности в развитии или росте грибов. Однако некоторые вторичные метаболиты играют роль в вирулентности, развитии и патогенности [1,2]. Микотоксины оказывают неблагоприятное воздействие на людей и животных даже при низких концентрациях [3,4], и распространению токсигенных грибов на продуктах питания и кормах всегда способствуют определенные факторы окружающей среды, такие как влажность и температура, а также определенные биотические условия (т.е.…”

Mycotoxins are a major food safety concern due to their adverse health and socio-economic implications not only in the Russian Federation but worldwide. The main regulatory documents that regulate the study of feed: GOST 10852-86. Oilseeds. Acceptance rules and sampling methods; GOST 12430-66. Agricultural products. Sampling methods during quarantine inspection and examination (as amended No. 1, 2); GOST 13586.3-83. Corn. Acceptance rules and sampling methods; GOST 27668-88. Flour and bran. Acceptance and sampling methods; GOST R ISO 6497-2011. Pet food. Sample selection.After analyzing the literature data from both Russian and foreign databases, it was found that this topic on the creation of sorption complexes in the diets of farm animals is relevant for many authors and many countries.The era of green nanotechnology, with its potential to use plant phytochemicals to produce nanomaterials, has greatly improved their safety for agricultural use as mycotoxin detoxifying agents. The combination of nanotechnology and plant extracts, as well as their phytochemicals, has shown significant results in the pharmacological, agricultural and cosmetic industries. Nanoencapsulated phytochemicals have shown strong efficacy over free form due to increased surface area, protecting the encapsulated compounds from internal and external environmental conditions.

Microscopic mold fungi are pathogens invisible to the naked eye that secrete dangerous metabolic products – mycotoxins. When exposed to various factors, mycotoxins can accumulate in plant and animal products. Getting into food and, as a result, into a living organism, they can lead to the appearance of mycoses and mycotoxicoses. The most common T-2 toxin of the Russian Federation territory. Due to the impossibility of completely eliminating microscopic fungi, the search for affordable preventive measures with detoxifying, immunostimulating properties remains relevant and promising. The aim of the study was to select adaptogens of various origins and evaluate their effectiveness in T-2 toxicosis of rats. The research was conducted on the basis of mycotoxin laboratory of the Federal state budgetary institution «Federal center for toxicological, radiation and biological safety» (Kazan). The tested adaptogens were echinacea purpurea grass, humic acids, biogenic stimulant ASD-2, zeolite from the Shatrashan deposit of the Republic of Tatarstan, and dry dead bee’s powder. In the course of work, the use of adaptogens such as echinacea purpurea, zeolite and dead bees turned out to be the most effective in relation to the survival of rats with T-2 toxicosis. The expected effect of a uniform increase in body weight of rats occurred, in turn, in groups of adaptogens with sorption capacity (humic acids, zeolite). The most striking positive picture during hematological examination was observed in groups using zeolite and dead bees. Based on the totality of the results obtained, it was concluded that zeolite and dead bees were the most effective in leveling the negative effects of T-2 toxicosis. The results obtained can become the basis for further development of a preventive complex.

Fungal contamination of feed ingredients is an important entry point for mycotoxins to increase the risk to animals and humans. Mycotoxicoses are an increasing threat to animal and human health with a high potential to cause significant economic losses in the food and feed industry. Contamination of agricultural crops with mycotoxins depends on physical and chemical factors that affect the production and accumulation of mycotoxins. Mycotoxins are secondary metabolite compounds that persist throughout the food chain due to their resistance to a wide range of environmental factors or manufacturing processes. Developing countries and rural areas dependent on local food production are at higher risk of mycotoxin contamination problems due to inadequate or insufficient implementation of food safety and quality control measures. The use of mycotoxin-contaminated feed is often due to an increased demand for less expensive feed ingredients to meet the growing needs of livestock production, including aquaculture. There are a number of efforts to reduce mycotoxins in raw and processed foods, both in pre-harvest stages, which inhibit toxin production in the field, and in post-harvest remediation strategies, reducing the concentration of mycotoxins in commodities.
