As hospitals struggle with increasingly hard-to-treat antimicrobial resistance (ARM) bacterial infections, related deaths now exceed 700,000 per year globally and are predicted to reach 10 million per year by 2050. There’s no denying that these statistics are both shocking and concerning, as existing antibiotics are increasingly losing their effectiveness.
While researchers work relentlessly to discover new classes of powerful antibiotics that could someday help to address a looming public health crisis, measures are being taken to restrict the impact of drug-resistant infections. AMR occurs naturally over time and is a complex issue with a multitude of factors to consider when it comes to quantifying causes and managing prevention. However, antibiotic resistance is accelerated by the misuse and overuse of antibiotics, and the link between animal ingestion of antibiotics and increasing resistance in humans is widely acknowledged.
Preventing Drug Residues Hitchhiking into the Food ChainVeterinary drug residues are making their way into the food chain, and human consumption of meat, fish, and crops is contributing to ARM, as well as other health epidemics such as hypersensitivity reactions and carcinogenicity. The use of antibiotics for livestock greatly exceeds the use for humans, and it is estimated that animal ingestion of antibiotics accounts for approximately 70-80 percent of total consumption worldwide. This is having a direct impact on human antibiotic intake.
Fortunately, there is a higher awareness of potential risks surrounding the (improper) use of veterinary drugs, and many countries have enforced legislation to restrict the usage of these substances. Agriculture will always include a level of necessary use for good animal welfare or to prevent crop failure, but the intention is to reduce veterinary drug residue levels in food products.
Multiclass Veterinary Drug Residue and Antibiotic AnalysisDetecting trace quantities of veterinary drug residues can be challenging for labs because they are complex, containing actives from a variety of chemical classes, such as antibiotics, antiparasitics, and non-steroidal anti-inflammatory drugs. While there are several analytical approaches available, few come close to mass spectrometry in delivering a fast and highly selective routine screening method.

Produced by certain moulds, thriving in crops such as grain, nuts and coffee, mycotoxins have contaminated agriculture and food production industries for a long time. To intensify the challenge, mycotoxins are resilient, not easily broken down and ensuring the safety of food supply chains requires comprehensive solutions and we are here to share those solutions with you.
Electron-Activated Dissociation (EAD) is transforming the fields of metabolomics and lipidomics by providing enhanced fragmentation techniques that offer deeper insights into molecular structures. In September, Technology Networks hosted a webinar, “Enhancing Mass-Based Omics Analysis in Model Organisms,” featuring Dr. Valentina Calabrese from the Institute of Analytical Sciences at the University of Lyon. Valentina shared her insights on improving omics-based mass spectrometry analysis for toxicology studies using model organisms, particularly in metabolomics and lipidomics. This blog explores the additional functionalities EAD offers, its benefits in untargeted workflows, its incorporation into GNPS and molecular networking, and the future role it could play in these scientific domains.
Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has gained significant attention in the clinical laboratory due to its ability to provide best-in-class sensitivity and specificity for the detection of clinically relevant analytes across a wide range of assays. For clinical laboratories new to LC-MS/MS, integrating this technology into their daily routine operations may seem like a daunting task. Developing a clear outline and defining the requirements needed to implement LC-MS/MS into your daily operations is critical to maximize the productivity and success of your clinical laboratory.
