“…Concentrations of heavy metals found in the eggs of our study (Table 3) were far below the toxic limits reported in the literature [30]. Other researchers have found increased concentrations of heavy metals and organochlorine compounds in eggs from hens kept in free-range systems [31].…”

Despite substantial interest in the trace element content of eggs by poultry breeders, nutritionists, and environmental scientists, available data about trace elements levels in eggs are scarce. Trace element contents in yolk and albumen of chicken, turkey, duck, goose, and pigeon eggs were analyzed to establish a baseline dataset and assess differences among trace element content in avian species. We measured the selenium (Se), zinc (Zn), manganese (Mn), cobalt (Co), copper (Cu), molybdenum (Mo), vanadium (V), chromium (Cr), nickel (Ni), arsenic (As), cadmium (Cd), and thallium (Tl) contents in both yolk and albumen by inductively coupled plasma mass spectrometry. One hundred twenty eggs deriving from 24 birds of each species, reared in the same poultry farm in northern Greece, were used; bird feed was common and based on cereals and legumes and contained no added vitamins or microminerals. Trace element contents in yolks were far higher than those in albumen, except for V and Ni. In yolks, the highest content for Se, Mo, and Tl were in pigeon eggs, for Zn, Mn, Cu, and Cr in turkey eggs, and for Co and Ni in goose eggs. In albumen, Se was highest in duck eggs, while Zn, Mn, and Co in pigeon ones. It is concluded that there is a substantial, up to threefold, variation for trace element contents in eggs among different domestic avian species offered the same feed.

“…On the other hand Rawn et al (2012) and Luzardo et al (2013) have found similar results in the concentration and frequency of detected OCPs, with only small differences among examined groups. These higher concentrations of OCPs in farm produced eggs may be due to eating soil and soil's creatures (worms and other insects) in farms that do not use barn floor, as they are more exposed to environmental pollutants than those are caged or in outdoor home produced with barn floor, where the possibility of eating soil does not exist (Van Overmeire et al, 2006;Windal et al, 2009). Table 2 showed that the egg-related calculated average daily intake of pesticides for people living in Sharkia Province is extremely lower than the ADI established by the WHO for these contaminants ( JMPR) and the level of exposure of this population through this food is lower than estimates recently published for other populations (Darnerud et al, 2006;Van Overmeire et al, 2006;Polder et al, 2010;Luzardo et al, 2013).…”

| This work is proposed to investigate pesticide residues in chicken eggs in El-Sharkia Province, Egypt. Analysis of pesticide residues was performed on 120 egg samples included 80 random edible egg samples (40 farm and 40 home produced hen eggs) and other 40 unhatched eggs. Edible eggs were collected from different stores, places and supermarkets. unhatched incubated eggs were collected from different hatcheries during the winter season. Organochlorine pesticides (OCPs) and organophophorous insecticides (OPIs) residue analysis of samples was done using Agilent Gas chromatograph (GC) Model 6890 N. The results revealed presence of OPIs in higher concentration in home produced eggs than that in farm produced eggs, while OCPs present in farm produced egg in higher levels than that in home produced one. Unlike other studies we have not found higher levels of exposure for most pesticides in those consumers choose home produced eggs, and even farm produced eggs. Regarding unhatched eggs dimethioate recorded the highest concentration which exceeded Maximum Residual Limits (MRLs) of (0.05) mg/kg in all the examined samples. None of the other detected pesticide residues exceeded (MRLs). It was concluded that the levels of pesticide residues in edible eggs either home or farm produced eggs should not exceed Accepted Daily Intake (ADI) established by the World Health Organization (WHO) Joint Meeting on Pesticide Residues Report ( JMPR). The study suggests the need for further investigations to determine toxic mechanisms by which dimethoate distress chick emberyos at different developmental stages and result in hatching failure.

From three studies (Leblanc et al, 2005;Van Overmeire et al, 2006;Gerber et al, 2009), 0.3 mg Mn/kg egg could be derived as the highest concentration for eggs. For milk, rather low manganese levels (up to 0.1 mg/L) are reported in two studies (Santos et al, 2004;Leblanc et al, 2005).…”

Manganese, an essential trace element, functions as an enzyme activator and is a constituent of several enzymes. Primary signs of manganese deficiency are impaired growth, skeletal abnormalities, depressed reproductive function, ataxia of the newborn and faults in lipid and carbohydrate metabolism. Manganous oxide and manganous sulphate monohydrate are safe sources of manganese for all animal species/categories, provided that the current maximum total contents of manganese authorised in feed are respected. Generally, dietary manganese does not appear to cause any adverse health effects in the population and has not proven to be a risk at the usual intake levels. Manganese intake resulting from the consumption of tissues and products of animal origin is low and not of concern for the safety of consumers, including more sensitive subgroups such as infants and elderly people. It is concluded that the use of manganous oxide and manganous sulphate monohydrate in animal nutrition is of no concern for the safety of consumers, provided that the current maximum total contents of manganese authorised in feed are respected. The handling of manganous oxide and manganous sulphate monohydrate poses a risk to users upon inhalation exposure. The additive manganous oxide should be considered as a potential skin and eye irritant and as a dermal sensitiser. Manganous sulphate monohydrate is not irritating to skin but it is an eye irritant; it is likely not a dermal sensitiser. The use of manganous oxide and manganous sulphate monohydrate in animal nutrition for all animal species is not of concern for the environment, provided that the current maximum total contents of manganese authorised in feed are respected. Manganous oxide and manganous sulphate monohydrate are efficacious sources of manganese in meeting animals' requirements.
