Abstract

Food safety issues and potential health risks in avian tissues are one of the most serious environmental concerns, this paper carries out probabilistic risk analysis methods to quantify trace elements bioaccumulation in chicken liver, gizzard, and lung content to assess the range of exposures for the people who consume the contaminated chicken. The concentrations of Al (aluminum), Mn (manganese), Cu (copper), Co (cobalt), and Zn(zinc) were measured using inductively coupled plasma mass spectrometry (ICP-MS), using the stock standard solution of heavy metals and blank sample. Results show the contents of elements in bird tissues samples were in the range of (18.68-62.24, 1.6-18.6, 0.12-0.61, 2.12-24.95, 35.10-93.85 µg/g for Al, Mn, Co, Cu, and Zn respectively. A risk assessment on human health beings due to consumption of chicken was performed using toxic reference benchmark, namely the reference dose (RfD). The hazard index (HI), sum of the hazard quotients calculated for all pollutants have shown that the risks of fowls consumption were generally low and are within safe limits.

Abstract

The toxic influence of dietary copper(Cu) and cobalt (Co) on the accumulation and body weight examined in broiler chicken. This experiment was conducted to investigate the toxic effects of dietary Cu and Co on chicks body weight and organ, content of the tissues of these two metals was also detected. One day age chicks of Gallus gallus domesticus fed diet supplemented with 500, 1000,1500ppm of Cu, second group exposure to 100,500, 1000ppm of Co in feed daily during 4 weeks. The control groups were fed without supplementation of metals. The concentrations of Cu and Co resulted in increased of Cu and Co content in liver, gizzard and muscle. Body weight of chicks was decreased by Cu and Co high concentration treatments. On the other hand, Liver weigh in chicks was significantly (P<0.05) decreased after Cu and Co treatments.
