All age groups are fond of bakery items, although middle-class and lower-class people in Bangladesh are especially prominent. However, this food product’s ingredients, manufacturing process, and packaging all have the potential for heavy metal contamination. As a result, the mean concentrations of Cr, Mn, Cu, Ni, Cd and Pb in 18 different brands of local bakery items, while others were from well-known brands readily available in Rajshahi City, were evaluated using an atomic absorption spectrometer. The concentrations of Cr, Mn, Cu, Ni, Cd, and Pb were 0.34–1.66, 0.29–1.70, 0.19–1.27, ND–7.04, ND–0.38, and ND–1.33 mg/kg, respectively. The order of the metal content was Ni> Mn> Cr> Pb> Cu> Cd, with their polluted values. According to the results, some cereals and cereal-based food product samples included levels of Ni, Pb, & Cd that were greater than the permissible range recommended by the World Health Organization. Fewer samples typically exceed the acceptable limit than all of them. The metals’ estimated daily intake levels did not exceed the permitted intake thresholds. On the other hand, the amounts of healthy nutritive metals like Mn and Cu that were ingested from that foodstuff were relatively small and barely met the daily demands for these nutrients. As a whole, the heavy metals’ estimated target hazard quotients were < 1, indicating that people who regularly use these goods on a daily basis shouldn’t have any health concerns.
