Abstract

The current study compared the same food products that were produced in a lab to random samples of street food sold in two cities (Tanta and Kafr-Elzayat) in the Gharbia governorate of Egypt. These foods included animal-based items e.g., Chicken Shawarma, Beef Shawarma, Hawaweshi, and plant-based items like Taamia and Koshary. Samples were gathered and chemically analyzed to determine their moisture, protein, fat, ash, and carbohydrate content. Results of heavy metal assessment showed that both plant-based and animal-based street-vendor foods had cadmium and lead contents that were higher than the EOS-permitted levels (2005). Regarding the area, Kafr-Elzayat city and Tanta city showed the greatest levels of cadmium and lead contamination, respectively. As street vendors add low-cost and subpar components at varying percentages to increase their profits, the acquired results showed that the mean values in the tested samples were considerably different from the other laboratory products compared to street products.
