The development and application of liquid chromatographic - mass spectrometric methods for the veterinary drugs carbadox and olaquindox
The use of veterinary drugs and zootechnical feed additives has become widespread in modern agricultural practice. Each Member State of the European Union is required to monitor for residues of these compounds in animal tissue and animal products that are intended for human consumption. From 1st …

Development of a liquid-liquid, solid-phase extraction (SPE), LC-MS/MS analytical method for qualitative and quantitative drug residue analysis in white-tailed deer
… problems within the deer industry; as a result, veterinary drugs are used. The administration of antibiotics for treatment of infectious diseases may lead to residues in tissues. The quality and safety of food from animal origin is a growing concern for public health agencies. It is important in …

Pharmacokinetic Evaluation of the Blood: Tissue Relationship in Poultry: Screening for Antibiotic Residues in Chicken Muscle
… persistent organic pollutants, pesticides and veterinary drugs. Some of these substances can leave residues in food products and possibly expose consumers to their potential toxic effects. To address these problems extensive regulatory efforts are devoted to prevent, detect and control these …

Optimizing Veterinary Drug Residue Monitoring in U.S. Cattle through Trend Analysis and Risk-Based Frameworks
Veterinary drug residues in U.S. cattle continue to raise important food safety, regulatory, and public health concerns. This dissertation integrates three complementary investigations to examine residue trends, evaluate human health risks, and propose an improved framework for national monitoring. …

QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) Extraction – Gas Chromatography for the Analysis of Drugs
… and co-workers initially for the extraction of veterinary drugs from animal tissue. Since its inception, it was discovered that this method is particularly adept for the extraction of polar and basic compounds, thus the majority of research previously performed using QuEChERS involves the …

Assessment of human exposure to toxic elements and veterinary drug residues from seafood consumption in Bangladesh
… with toxic elements and residues of forbidden veterinary drugs, although not all types of fish consumed have been analyzed. Estimation of dietary exposure to these chemicals from total seafood intake in the Bangladeshi population would be an important tool in policy planning and mitigation …

Advanced systems for the rapid detection of anthelmintic drugs in food
… and validated for the detection of anthelmintic veterinary drugs in liver tissue and milk using a QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) extraction procedure. The first screening assay was developed to detect 11 benzimidazole carbamates in milk and liver. In bovine milk the …

Analysis of aqueous matrices using supercritical fluid extraction in conjunction with chromatographic spectroscopic and mass spectrometric techniques
… chemical ionization for the analysis of three veterinary drugs at the ppb level. Results of off-line and on-line studies involving electrospray tandem mass spectrometry with high pressure liquid chromatography for the analysis of a range of ionophores at the low ppb level following their …

Characterisation of the sulfotransferases catalysing the sulfation of xenobiotics and steroids in bovine liver
… part of the human food chain. Administration of veterinary drugs and other xenobiotic compounds to cattle can often result in the accumulation of metabolic residues in edible tissues that can potentially affect humans through the food chain. An understanding of drug metabolism in this species is …

The role of supplementary feeding sites in vulture conservation in South Africa
… based on whether they had been treated with veterinary drugs, relatively few managers (10%) did the same for lead (Pb) contamination. Worryingly, only 30% of managers consider threats to vultures, such as the proximity of power lines, when deciding on a location for their SFS. Overall, …
