Abstract Canned food of all kinds, whether fish, beef, or chicken, provided man the opportunity to learn about food that was not produced in his country, as well as to eat food in situations where fresh food could not be made or was impossible to get, such as circumstances of radioactive contamination or war. Canned food can be used as a substitute to fresh food in locations without stores or cultivation, such as safari areas in the desert, woodlands, or when traveling by sea. Canned fish, beef, and poultry are good sources of animal protein that are high in essential amino acids and micronutrients. Canned food of animal origin is exposed to many pollutants, including those derived from basic materials used in manufacturing, because environmental pollutants resulting from various human activities such as mining, fertilization, and industrial waste of petrochemicals that are stored in the tissues of fish, livestock, and poultry. Contamination is also increased by metals used in the canning process, such as tin. This study aimed at estimation of the residual contents of six heavy metals, namely lead (Pb), cadmium (Cd), arsenic (As), mercury (Hg), aluminum (Al), and tin (Sn) in three types of commercially processed canned food including canned fish, meat, and chicken products from Zagazig city, Egypt. |
