Objective: Comparative study of heavy metal contamination of local food products produced in ecologically unfavorable areas by farmers and personal subsidiary farms. Material and Methods: Sampling of local food products was carried out in the summer and autumn periods of 2017-19 on the territories of farms and personal subsidiary farms in a number of districts of the Saratov region. Determination of the content of metals in food samples: lead, cobalt and arsenic was performed using adsorption inversion voltammetry on the analyzer "IVA-5". The mercury content was determined by the method of flame-free atomic absorption spectrometry of cold steam on the analyzer "RA 915 M". Results: It is found out that the median concentration of mercury and cadmium in foods by Engels, Fedorovsky, Saratov, Balakovo and Marks areas, regardless of the form of business ownership, and determine the 90-percentile was closest to the remote control. Bread and meat were the most vulnerable local products when combined with heavy metal contamination. Conclusion: Median concentrations of heavy metals in food samples grown on the territories of farms and private farms and used as local food had no significant differences in their quantitative contamination.
