The environmental pollution Polychlorinated dibenzo-p-dioxins, the polychlorinated dibenzofurans PCDD/F and the polychlorinated biphenyls (PCB) contamination in the food from the animal origin were caused by the industrially produced feed from the free range chicken, sheep, and beef. To elucidate the entry of the the environmental pollution polychlorinated biphenyls (PCBs) and the Polychlorinated dibenzo-p-dioxins, polychlorinated dibenzofurans PCDD/Fs in the food related to the environmental contamination. The food products from the farm animals are sensitive to the environmental pollution dioxin/ polychlorinated biphenyls (PCB) exposure, the suckling calves and the laying hens housed outdoor at the soil concentrations that have previously been considered as safe. In the beef/veal when the soil is contaminated. The eggs/ the broiler, this can occur. The eggs consumer's especially the young children can easily exceed the health-based guidance values, the tolerable daily intake. The soil, the chicken eggs exposure pathway is probably the most sensitive route for the human exposure to both the environmental pollution dioxin-like polychlorinated biphenyls and the PCDD/Fs from the soil and needs to be considered for the soil guidelines. The calves from the suckler cow herds are the most prone to the impacts of the dlPCB contamination due to the excretion/accumulation via the milk. The environmental pollution polychlorinated biphenyls (PCB) (and the PCDD/F) intake for the free-range cattle stems from the feed and the soil. The sources for the PCDD/Fs and polychlorinated biphenyls (PCBs) relevant to the environmental contamination in polychlorinated biphenyls respect to the food safety. It also includes the considerations on the assessment of the emerging persistent organic pollutants. The major sources of the environmental pollution PCDD/F and the dl-PCB contamination of the food of the animal origin are the soils contaminated from the polychlorinated biphenyls (PCB) and the PCDD/F releases; the polychlorinated biphenyls (PCBs) emitted from the buildings and the constructions; the environmental pollution polychlorinated biphenyls (PCBs) present at the farms. The impacted areas need to be assessed with the respect to the potential contamination of the food producing animals. The livestock management techniques can reduce the exposure to the environmental pollution PCDD/Fs and the environmental pollution polychlorinated biphenyls (PCBs). The control and the reduction measures are recommended for the emission sources and the new listed and the emerging persistent organic pollutants to ensure the food safety.
