| Abstract | ||||
| The present study aimed to investigate the level of heavy metals bioaccumulation, mycotoxins contamination and macro-mineral composition of broiler chicken giblets (heart, liver and gizzard) from retail markets in El-Beheira Governorate. Ninty-six fresh samples of liver, gizzard and heart (thirty-two of each) were randomly collected from retail markets of four different cities (Damanhour, Kafr-El Dawar,Hosh Esa and Itay Elbarod) in EL-Beheira Governorate, Egypt. The concentrations of metals; Lead (Pb), cadmium (Cd), iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), Selenium (Se), arsenic (As) and macro-mineral composition; sodium (Na), potassium (K), calcium (Ca), magnesium (Mg) were determined by using atomic absorption spectrophotometer and phosphorous (P) by a colorimetric method. However, mycotoxins [Aflatoxins (AFs) and Ochratoxin A (OTA)] were determined by fluorometer. The significant elevation in the concentration level of Cd and Pb limit in livers samples from retail market of Damanhour and Kafr El-Dawar cities was above the tolerable. As and OTA were not detected. The mean concentration of Fe, Cu, Zn, Mn, Se and AFs were found below the tolerable limit in all tested chicken giblet samples. However, Fe, Cu, Zn levels significantly increased, while, Se levels significantly decreased in Hosh Esa and Itay-Elbarod giblet samples. Metals, macrominerals and AFs concentration were the highest in liver followed by gizzard and heart of chickens except Na which was the highest in heart followed by gizzard and liver. In addition, aflatoxins significantly increased while, P and Ca significantly decreased in Hosh Esa and Itay-Elbarod giblet samples. In conclusion, chicken giblet samples from Damanhour and Kafr El-Dawar retail markets were the worst contaminated samples with Pb and Cd. However, chicken giblet samples from Hosh Esa and Itay-Elbarod were the worst contaminated samples with AFs. | ||||
