Analytics of t-2 toxin distribution data in the Republic of Tatarstan
Abstract
The study of the distribution of T-2 toxin in the Republic of Tatarstan is presented. T2 toxin is known to be harmful to the body even in low concentrations. The Republic of Tatarstan, due to the type of climate and humidity, creates comfortable conditions for the spread of fungi producing T-2 toxin.
The purpose of the study is to analyze the contamination of feed in the Republic of Tatarstan based on modeling the situation from randomly selected types of samples in the period 2017-2019. A study of 1191 samples of various feeds (corn, wheat, barley, oats, mixed feed) from various regions (central, western, northern, southern and eastern parts) was carried out. The main aspects of our study were: the study of the distribution of T-2 toxin relative to geographical location (north, south, west, east and central), type of food and time period. The identification of the T-2 toxin was performed by an indirect, competitive enzyme-linked immunosorbent assay.
The presence of T-2 toxin was established in 427 samples, which corresponds to 35.8% of the total number of samples, of which 243 samples contained a dangerous concentration for young farm animals (> 50 μg / kg), which is 56.9% of the total positive samples and 20.4% of the total number of samples. In 134 samples of T-2, the toxin was found in a concentration exceeding the maximum permissible (100 μg / kg), which is 11.2% of the total number of samples and 31.6% of positive samples. Corn was the most contaminated sample, T-2 toxin was detected in 122 samples (49.6%). Higher concentrations of T-2 toxin were found in the western part of the Republic of Tatarstan, but at the same time, samples from the southern part of the Republic of Tatarstan have the highest percentage of T-2 toxin contamination - 43.6% of the samples. In the context of data by quarters of the year, the occurrence of T-2 toxin fluctuated at the level of 31- 44%.
