The use of feed additives based on the so-called “phytobiotics” and a complex of trace elements is a promising direction in the nutrition of farm animals and birds. However, along with the positive characteristics associated with the increase in body weight, environmental friendliness of production, etc., these biologically active additives may have a negative effect on animals and humans associated with the toxicity of the used components. In this regard, the purpose of this study was to determine the toxic effect of such feed additives as phytochemicals and trace element metals using a recombinant luminescent strain Escherichia coli K12 MG1655 (pXen7) and a representative of ciliated protozoa Stylonychia mytilus. During the studies, the absolute toxicity of the Cu biocomplex and Scutellaria baicalensis was recorded in relation to the test organisms used. Against this background, Artemisiae absinthil herba and the Digestarom agent showed the smallest toxic effect. The toxic effect of other tested bio-additives was in high doses (0.625-10 mg/mL) and disappeared with a decrease in the concentration of the tested feed additive.
