The search for healthier, innovative and practical products hasmoved the exponential growth of the dairy industry. Various foods have intheir composition additives to enhance color, smell, texture and ensure greaterdurability. Rigorous quality control for the detection of contaminants andother potentially toxic and carcinogenic substances is essential for theindustry. The objective of this work was to quantify the levels of lead, cadmiumand chromium metals, which present a higher toxic potential in relation tohealth, which ends up affecting the children in a more significant way. Thedigestion method was used in a muffle oven. All three analyzed brands showedhigh levels of chromium and cadmium and absence of lead. The X markshowed the highest levels of these metals, followed by the Z mark, and the Ymark the lowest concentrations, but all with values above that established bythe legislation. Therefore, all the analyzed brands presented positive results
