Pesticide & Veterinary Residue Test Service

Pesticide & Veterinary Residue Test Service

Pesticide and veterinary drug residues are among the most critical concerns in food safety and public health. Pesticide residue refers to the trace amounts of pesticides remaining on or in food products—such as fruits, vegetables, grains, or aquatic goods—after application. With over 1,000 synthetic compounds currently used as insecticides, herbicides, fungicides, and other agrochemicals, residue testing is essential to ensure that consumption does not exceed safe limits.

Similarly, veterinary drug residues refer to the parent compounds or metabolites remaining in edible animal products such as meat, eggs, and dairy. While veterinary drugs are crucial for disease control and production efficiency in livestock, improper or excessive use can result in harmful residues that may impact human health, animal welfare, and the environment.

Creative BioMart provides professional Pesticide and Veterinary Residue Testing Services with exceptional sensitivity, accuracy, and efficiency. We offer rapid, comprehensive screening for a wide range of commonly used and regulated compounds. Our pesticide residue testing covers organophosphates, organochlorines, pyrethroids, carbamates, and more. For veterinary drug residues, we detect key classes such as tetracyclines, quinolones, sulfonamides, chloramphenicol compounds, β-receptor agonists, nitrofurans, and β-lactams.

Testing Methods We Use

To ensure the highest standards of sensitivity, accuracy, and reliability in detecting trace levels of pesticide and veterinary drug residues, Creative BioMart employs a suite of advanced analytical techniques:

• Gas Chromatography (GC): Ideal for separating and analyzing volatile compounds, GC is commonly used for screening pesticide residues in food and environmental samples.
• Gas Chromatography-Mass Spectrometry (GC-MS/MS): This technique combines the separation power of GC with the molecular identification capabilities of mass spectrometry, providing high specificity for complex pesticide mixtures.
• High Performance Liquid Chromatography (HPLC): HPLC offers excellent precision in quantifying non-volatile and thermally unstable compounds such as veterinary drug residues.
• Liquid Chromatography-Mass Spectrometry (LC-MS/MS): A powerful method for simultaneous multi-residue analysis, LC-MS/MS delivers high sensitivity and selectivity, especially suited for low-concentration detection in complex matrices.

These robust technologies allow us to deliver fast, reliable, and regulatory-compliant results across a wide variety of sample types.

Case Studies on Multi-Residue Analysis in Agricultural Products

As an alternative, we present selected published research articles as representative case studies.

Case 1: Tetracycline, sulfonamide, and erythromycin in farmers’ market foods

Sarkar et al., 2023. doi:10.3390/vetsci10040243

This study investigated antibiotic residues in beef, eggs, and honey labeled as “antibiotic-free” from farmers’ markets in East Tennessee. Using cELISA, researchers found that all samples contained tetracycline, and most also had sulfonamide and erythromycin residues. While residue levels in beef and eggs were below U.S. maximum residue limits (MRLs) and considered safe, no MRLs exist for honey, making its safety unclear.

Despite being marketed as “antibiotic-free,” the presence of residues suggests possible contamination or mislabeling. These findings highlight the need for stricter monitoring and further investigation into the sources of antibiotic residues in supposedly clean food products.

Case 2: Pesticide residues and consumer risk in Aegean produce

Kazar Soydan et al., 2021. doi:10.1007/s11356-021-12580-y

This study, conducted in Turkey’s Aegean region between 2012 and 2016, analyzed 3,044 fruit and vegetable samples for pesticide residues. Out of these, 11.6% exceeded the Turkish maximum residue limits (MRLs), with 64 different pesticides detected. Common pesticides with high MRL violations included azoxystrobin, triadimenol, carbendazim, and chlorpyrifos. Multiple residues were also found in many samples, with some containing five or more pesticide types.

Despite the violations, estimated daily intake (EDI) and hazard quotient (HQ) values indicated low health risks, with HQs as low as 0.01 in fruits like dried apricots, grapes, and strawberries. However, the frequent presence of multiple residues highlights the need for continued monitoring to ensure consumer safety.

Experiences with Our Pesticide and Veterinary Residue Test Service

"We needed a comprehensive analysis of Cypermethrin and Chlorothalonil residues in a batch of imported leafy vegetables, and Creative BioMart delivered fast, precise results using GC-MS/MS. Their technical support team also helped us interpret the data in line with EU MRLs."

— Head of Food Safety | Global Agricultural Importer

"Creative BioMart has been instrumental in helping us meet domestic and international residue limits. Their multi-residue LC-MS/MS panel identified low-level traces of Enrofloxacin and Tetracycline in our poultry products that we wouldn’t have caught with standard in-house testing. Thanks to their insights, we avoided a potential compliance issue during export."

— Quality Control Manager | National Poultry Processor

"For our aquaculture business, consistent testing for organophosphates like Malathion and veterinary drugs like Furazolidone is critical. Creative BioMart’s turnaround time and reporting detail are among the best we've experienced."

— Technical Director | Marine Food Supply Company

"We were facing unexplained antibiotic residue flags in our dairy supply chain. Creative BioMart pinpointed the issue with their β-lactam and sulfonamide panels and helped us trace contamination back to a veterinary treatment error. Their precision and advisory support saved us from a major product recall."

— Veterinary Compliance Officer | Dairy Cooperative
