GM analogues have about 30 plant species, and main share from GM crops belong to soybean and corn. According to the literature data, the introduction of GM fodder in the diet of laboratory mice and rats was accompanied by negative consequences for the health of experimental animals and their offspring. Corn is a component of animal feed and popular product among people, especially sweet canned corn. The lack of experimental data regarding effects of canned sweet GM corn on an organism was the drive behind our research subject. The objective of the research was a comparative analysis of hematological and biochemical parameters of laboratory mice with a conserved GM corn based diet and without it. Clinical blood analysis indicated the development of hyperchromic anemia, leukocytosis due to an increase in the fraction of medium blood cells and thrombocytosis in experimental group mice. Biochemical studies of these mice blood revealed signs of renal and liver pathology, myocardial damage and hyperproteinemia. A comparative analysis of the hemato-biochemical status of laboratory mice indicated the development of signs of anemia, intoxication and allergy in the group of mice with a conserved GM corn based diet as compared to intact mice of the control groups.

In this study we carried out a physicochemical analysis of fatty acid esters (FFA) obtained from the biomass of larvae, which can be used as ingredients in the food industry and for the manufacture of feed. The acute toxicity of fatty acid esters obtained from the biomass of Hermetia illucens larvae was determined. It was revealed that the acid and peroxide values of the fat fraction obtained from the biomass of Hermetia illucens larvae are within the limits established by the norm, which indicates the high quality of this product. The fatty acid composition is represented mainly by lauric, palmitic, oleic and myristic acids. It was shown that the differences in fatty acid composition of the samples, obtained from the biomass of Hermetia illucens larvae manually and using the Soxhlet extraction apparatus, were insignificant and within the acceptable values. In the study of presence of toxic elements in fat fractions, lead, cadmium, arsenic, mercury, iron were not detected or they did not exceed the established values.
