Farag Mahmoud Malhat

The concentrations of 12 organophosphorus Pesticides (OPPs), widely used in crops used for animal feed were determined in 100 samples of cowÂ’s milk collected fromfive districts of El-QalubiyaGovernorate, Egypt duringMarch toApril, 2011. OPPs residuesweremeasured by gas chromatographywith a flam photometric detector. Approximately 8 % of the samples contained detectable levels of OPPs residues. Two samples contained residues exceeding established maximum residue limits (MRL), and the OPPs present in these samples were dichlorvos and chlorpyrifos. Samples containing more than one compound were not found. Frompublic health point of view, the observed levels of OPPs residues in cowÂ’s milkÂ’s in this study do not pose a serious health risk to the consumers.
