Over 800 pesticides are currently approved for use in one or more EU countries. The maximum residue levels (MRL) for agricultural pesticides are derived from field trials conducted under good agricultural practice (GAP). The MRL is a legally enforceable limit related to GAP. The results from field trials would only be used to establish MRLs if the estimated intake of residues did not exceed the...

background: the objective of this study was to determine the residual concentrations of ethion and imidacloprid in cucumbers grown in greenhouse. the effect of some simple processing procedures on both ethion and imidacloprid residues were also studied. methods: ten active greenhouses that produce cucumber were randomly selected. ethion and imidacloprid as the most widely used pesticides were m...

BACKGROUND: The presence of aflatoxin M1 (AFM1) andantibiotic residues in milk and milk products is a public healthconcern. Milk and milk powder have the potential forintroducing AFM1 and antibiotic into human diet. In recentyears, milk powder has been used on a large scale in dairyfactories. Consequently, antibiotic residues and aflatoxincontamination control in these products has gained impor...

Pesticide residues in fruits and vegetables are one of the highest concerns of consumers who need food safety. In this study, forty-eight pesticide residues from different chemical structure including organochlorine, organophosphorus, organonitrogen, dicarboximides, strobilurin, triazine, pyrethroids and other chemical groups. in 85 fruits and vegetables were determined and confirmed by GC-MS. ...
