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...
A multi-residue method was developed for monitoring antibiotic residues in milk using liquid chromatography coupled to a tandem quadrupole mass spectrometer (LC/MS-MS). Two very short extractions followed by two LC/MS-MS acquisitions allowed the screening of 58 antibiotics belonging to eight different families (penicillins, cephalosporins, sulfonamides, macrolides, lincosamides, aminoglycosides...
BACKGROUND The abundant use of tetracycline antibiotics in veterinary medicine may result in the presence of their residues in milk at unsafe concentrations that can adversely affect public health. The aim of the current study was to evaluate the risk of tetracycline residue (TET) intake via milk consumption amongst different age groups of human consumers in Iran. METHODS To quantify the drug...
Background: Measuring metabolic parameters in the blood has been an indispensable tool for assessing productive and health status of dairy cows more than 100 years. The values laboratory depend on various preanalytical, analytical postanalytical factors. most important preanalytical factors are sample transport time temperature, hemolysis, anticoagulant type, volume.Preanalytical can lead to re...
