The infamous horsemeat scandal of 2013 shined a spotlight on the questionable integrity of our meat supply. What followed was a lengthy investigation as the extent of the scandal unraveled before our eyes, reaching far beyond the European borders into Russia, India, China, and the United States. All this simply highlights the growing need for analytical methods that could effectively detect adulterated meat with undeclared species.
Finding the Needle in a HaystackAs analytical chemists, we are always looking for cutting-edge and innovative ways to better detect the “unusual” or “unknown.” With the wider requirement from global governments to regulate food manufacturing, the threshold for undeclared species in meat products gets lower and lower, driving the needle deeper into the haystack.
This means it is imperative that analytical methods are sensitive and accurate enough to screen for the presence of meat adulteration in food products. The common methods of choice for meat speciation—polymerase chain reaction (PCR) and enzyme-linked immunosorbent assays (ELISA)—are not up to par.
PCR, for instance, amplifies fragments of DNA extracted from food samples and demonstrates reliable sensitivity in unprocessed products. However, as DNA can be easily disrupted or removed during food processing and manufacturing, PCR is ineffective with regards to processed or cooked meat products.
While ELISA is relatively quick and simple to perform, it has poor selectivity and is susceptible to cross-species reactivity. This can lead to a higher number of false positive or negative results. Moreover, most ELISA tests lack multiplexing capabilities.
As a result, routine food testing labs are exploring alternative methods to test meat products for authenticity, in efforts to more accurately identify the species present.
Fight Back with LC-MS/MS Meat Speciation Testing SolutionsWhen all seems lost, fret not. LC-MS/MS to the rescue! In leading the fight for meat speciation and authenticity testing, LC-MS/MS solutions take a comprehensive approach.
LC-MS/MS meat speciation testing solutions enable:
Would your food testing lab benefit from faster, more conclusive meat speciation results? Find out how LC-MS/MS can revolutionize your labs by visiting our Meat Species Testing and Adulteration Analysis page, packed with videos, tech notes, solution guides, and so much more.Find out How >
At SCIEX, innovation doesn’t stop at instruments; it extends to how you interact with your LC-MS/MS or CE systems every day. That’s why we’re excited to introduce the SCIEX Now spring 2026 improvements: a set of meaningful enhancements shaped directly by your feedback.
In today’s fast-paced analytical laboratories, uptime is not just important; it is mission-critical. Whether you are running high-throughput bioanalysis, environmental testing, or pharmaceutical workflows, every minute of LC-MS downtime can impact productivity, data quality, and timelines.
That is why we are excited to introduce a smarter and faster way to troubleshoot.
Ultra‑low reporting limits, expanding target lists, and the constant risk of background contamination mean that even small missteps before injection can compromise data integrity. PFAS can be introduced at nearly every stage of prep, from sampling containers and PPE to SPE cartridges, filters, solvents, and lab consumables, making contamination control as critical as analyte recovery.
