Abstract
ABSTRACT
Heavy metals are considered highly toxic and their presence in foods may constitute human health hazard.
Accordingly, 90 random samples of frozen fish fillets, including Oreochromis niloticus, Lates niloticus and imported Basa( 30 of each) were gathered from fish markets in Menoufia governorate,Egypt. The collected samples were examined for detection of their contamination with certain heavy metals (mercury, lead and cadmium) using Atomic Absorption spectrophotometer (AAS). Regarding mercury the mean value of Oreochromisniloticus (1.02+ 0.01mg/kg) ,Latesniloticus(0.67+ 0.01mg/kg) and imported basa (0.45+0.01mg/kg) ,while the lead mean value of Oreochromis niloticus (0.65+ 0.0 mg /kg),lates niloticus(0.41+0.01mg/kg)and imported Basa (0.24+0.01mg/kg ) , Finally cadmium mean value of Oreochromis niloticus(0.36+0.01mg/kg) ,lates niloticus(0.22 + 0.01 mg/kg)and imported Basa (0.10+0.01 mg/kg).
The obtained results indicated that the highest levels of mercury, lead and cadmium were recorded in Oreochromis niloticus, however the lower levels present in imported basa.It is evident that the maximum allowable limits of Egyptian regulations were surpassed by the amounts of heavy metals in certain fish samples.
The ability of Lactobacillus rhamnosus and chitosan to decrease mercury،lead and cadmium contamination were also studied. The public health significance and some recommendations to produce fish product safe for human consumption were discussed.
