Bad Leftovers: Antibiotic Residues in Food

Jun 20, 2019 | Blogs, Food / Beverage | 0 comments

We know that antibiotics used to treat livestock can end up in the food we eat. Routine food testing labs are essential for detecting compounds, like these, that can be dangerous to our health. Antibiotic residues include both parent molecules and metabolites left over in the animal’s body after treatment. They are a class of compound that causes a lot of concern. Using antibiotics in livestock, and its alarming connection to antibiotic-resistant bacteria is not a new topic. Antibiotic resistance is known as a global threat to human health. Many countries have ongoing efforts to both stop the overuse of antibiotics and to keep track of the effect of antibiotic-resistant bacteria on the population.

Antibiotic residues in food that comes from animals are a complex threat. Antibiotics are used to promote growth and to stop microbial infections in livestock. The more times the bacteria get a non-lethal dose of the antibiotic, the more likely they are to become immune to that antibiotic. A similar thing happens when humans consume food products from the treated livestock that contain residues of these antibiotics. The exposure can increase the chance of antibiotic resistance, transfer resistant bacteria to humans, and cause problems in people with hypersensitivity to the antibiotic. Hundreds of thousands of people die globally from infections caused by antibiotic-resistant bacteria each year.

Many countries have set tolerance limits (or maximum residue limits) for antibiotic residues in food products. Keeping human exposure below the maximum residue limits is the main goal of routine food testing. It is important to accurately monitor these levels for the sake of public safety. Robust and reliable analytical methods are required. Detecting multiple antibiotics with a single analytical method increases the efficiency of the monitoring. Methods that meet the performance levels required by regulatory agencies are also essential.

The SCIEX Solution for Routine Testing Labs
LC-MS/MS technology is a valuable tool to help fight the threat of antibiotic resistance. A complete analytical solution includes hardware, software, and a proven method to produce reliable LC-MS/MS data. An ideal method achieves the selectivity and sensitivity required to meet regulatory requirements. It also minimizes sample preparation and detects multiple analytes for increased throughput.

Find out how the SCIEX Triple Quad™ 3500 System with Turbo V™ source and MultiQuant™ software can help reduce exposure to antibiotic residues in our food. Complete the form on your right to access practical applications performed on the TripleQuad 3500 System including a method to analyze chloramphenicol and tetracyclines in honey, milk, meat, and shrimp.

What are the differences between EPA methods 533 and 537.1?

With the risk of per- and polyfluoroalkyl substances (PFAS) contamination and accumulation in humans and wildlife on the rise, it is important to continuously improve and demonstrate capabilities for accurate and precise low-level quantification in research and...

Rescheduling a Schedule I substance, and the Delta-8 controversy

Did you know that in the US, drugs and other chemicals are classified into 5 distinct categories depending on the drug’s acceptable medical use and its potential for abuse or dependency?  Drugs federally classified as Schedule I substances by the US Drug Enforcement Administration (DEA) are considered to have the highest potential for abuse and for creating severe psychological and/or physical dependence. In addition to heroin, LSD and MDMA (ecstasy), cannabis is classified as a Schedule I substance in the Controlled Substance Act of 1970, which means it has no approved medical usage.

The pros and cons of using solid phase extraction and direct injection methods for PFAS testing

US Environmental Protection Agency (EPA) and Department of Defense (DoD) methods for testing per- and polyfluoroalkyl substances (PFAS) in drinking water require using solid phase extraction (SPE). SPE has been used extensively in environmental contaminant analysis both for concentrating large sample volumes (improving method sensitivity) and removing matrix interferences (sample cleanup).
