Abstract

Monitoring the quality and safety of food products is still considered a topical issue. The evaluation of values of the results of sampling of alimentary raw materials and food products in previous 5 years has shown that the maximum number of obtained results of sampling lies within the following intervals: less than 0,001 mg/kg for cadmium, less than 0,01 mg/kg for lead, less than 0,02 mg/kg for arsenic. To consider values of results of sampling of alimentary raw materials and food products for content of such toxic elements as cadmium, arsenic, and lead we have revealed the results of studies of sampling of 2 groups of products, namely the group ‘Milk and Diary Products’ and the group ‘Bakery and Confectionery Products’. The evaluation of results of sampling for content of arsenic in the concentration interval of less than 0,02 mg/kg and 0,02–0,05 mg/kg allows to determine the prevalence the group ‘Milk and Diary Products’ which comprises 61,7 and 32,6% of the total number of sampling. In the concentration interval of 0,05–0,10 mg/kg and 0,1–1,0 mg.kg we can highlight the prevalence of the group ‘Bakery and Confectionery Products’ which comprises 11,6 and 6,1% of the total number of sampling respectively. Evaluation of the results of sampling for content of lead in the concentration interval less than 0,01 mg/kg allows to determine the prevalence of the group ‘Milk and Dairy Products including Butter and Sour Cream’ which comprises 83,5% of the total number of sampling. In the concentration intervals of 0,01–0,03 mg/kg, 0,03–0,05 mg/kg, 0,05–0,10 mg/kg, 0,1–1,0 mg/kg the group ‘Bakery and Confectionery Products’ prevails which comprises 15,2; 6,3; 4,4; 3,2% of the total number of sampling respectively. The evaluation of results of sampling for content of cadmium in the concentration interval of less than 0,001 mg/kg allows to determine prevalence of the group ‘Bakery and Confectionery Products’ which comprises 73,5% of the total number of sampling. In the concentration intervals of 0,001–0,005 mg/kg, 0,005–0,010 mg/kg the group ‘Milk and Diary Products’ prevails which comprises 41,3 and 14,8% of the total number of sampling respectively. In the concentration intervals of 0,01–0,05 mg/kg the group ‘Bakery and Confectionery Products’ prevails which comprises 12,6% of the total number of sampling. The content of cadmium, lead, and arsenic in all the samples of food raw materials and food products does not exceed the maximum permissible concentrations which allows to make a conclusion about the low level of the delivery of these toxic elements in the human body orally with food.
