Study of the effect of mercury and arsenic contamination of feed on the safety of livestock products

A review of some aspects obtaining environmentally friendly livestock products studies under the conditions of agricultural territories technogenic pollution of for the case of high levels of mercury and arsenic in the agrosphere is presented. The mercury and arsenic toxic effects of on the farm animals physiological state and productivity when taken with the diet, even in small quantities, have been confirmed. The simultaneous analysis of wool, blood and urine animals samples expediency for the presence of mercury and arsenic in order to predict the possible consequences of exposure to these toxicants on the animal organism and determine the environmental safety level of the products obtained is noted. The importance of the public health risk assessing from present in food toxicants impact is emphasized. The conclusion about the predicting the possible mercury and arsenic content of in food raw materials of animal origin problem relevance and the need to ration their intake with the diet in order to obtain animal products that meet sanitary and hygienic requirements is made.
