Assessment of Pesticide Residues in Edible and Unhatched Chicken Eggs in Sharkia Province, Egypt

Abstract

| 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.

Pesticides (Hexachlorocyclohexane, Aldrin, and Malathion) Residues in Home‐Grown Eggs: Prevalence, Distribution, and Effect of Storage and Heat Treatments

“…A study conducted in Jordan on 134 egg samples analyzed for OCP residues showed that 28% (38 samples) of the examined eggs were contaminated with OCP residues with a high level of HCHs and DDTs (Ahmad et al., ). A study in Egypt detected aldrin in 25% of farm or home‐grown eggs (Abdelfatah & Abu‐Zeid, ), which is lower than our finding (34%). Study in Spain showed that examined egg samples were free from any traces (Luzardo et al., ) whereas a report from Belgium showed that aldrin was present in only 3% to 5% of the samples above the acceptable limit, although its uses was banned for more than 25 years (Windal et al., ).…”

Prevalence of mites and their impact on laying hen (Gallus gallus domesticus) farm facilities in Egypt, with an analysis of deltamethrin residues in eggs and tissue

“…A review of the MRLs for DMT in poultry tissues and eggs according to European regulations (European Food Safety Authority, 2015) showed that 20 μg/kg was the MRL for poultry muscle, liver and eggs, while poultry fat was 100 μg/kg. Abdelfatah and Abu-Zeid (2015) showed that DMT residues were detected in 25% of farm-produced eggs.…”

“…Deltamethrin (DMT) (one of the pyrethroids) has become an insecticide of choice in many countries owing to its low toxicity (Elias, 2013), while a number of new publications confirmed its toxicity in humans and birds (Chandra et al, 2013). A determination of DMT residues in eggs and meat was studied by Abdelfatah and Abu-Zeid (2015).…”
