Sulfonamide dosage

Sulfonamides antibiotics historically used in human and veterinary medicine, but their presence in food is now strictly regulated. These molecules, sometimes used in livestock farming to prevent or treat certain infections, can leave undesirable residues in meat, milk, eggs, or fish. Therefore, measuring sulfonamide levels is essential to ensure food safety and compliance with European and international regulations.

Analytical methods for the determination of sulfonamides

The analysis of sulfonamides relies on sensitive and selective techniques:

• HPLC (high-performance liquid chromatography) for the separation of molecules.
• LC-MS/MS (liquid chromatography coupled with tandem mass spectrometry) for very low concentration detection and specific identification.

These methods meet the requirements of Regulation (EC) No 37/2010 setting maximum residue limits (MRLs) for veterinary antibiotics in food. They are comparable to the techniques used for the determination of streptomycin and antibiotics , which are also part of food safety controls.

Industrial and regulatory applications

Sulfonamide assays are applicable in several contexts:

• Human food: verification of residues in meats, dairy products, eggs, fish and processed products.
• Veterinary control: monitoring the use of antibiotics in livestock farming and preventing contamination of the food chain.
• Environmental monitoring: detection of traces of antibiotics in wastewater, effluents or aquatic environments.

These analyses are essential to comply with European regulations and meet the requirements of quality audits, certifications and health inspections.

Matrices analyzed for sulfonamides

YesWeLab offers sulfonamide analysis in a wide range of matrices: meat and offal, eggs, milk and dairy products, fish and seafood, processed foods, water, and environmental samples. Each matrix is ​​prepared according to tailored protocols to guarantee reliable, reproducible, and standards-compliant results.

Security and compliance issues

The presence of sulfonamide residues in food raises several major issues:

• Protecting public health by avoiding exposure to potentially harmful residues.
• Preventing the development of antibiotic resistance is a global health challenge.
• Compliance with the maximum residue limits set by EC Regulation No. 37/2010.
• Promoting food supply chains by highlighting strict quality controls and products that meet consumer expectations.

These issues are similar to those of other critical analyses such as pesticide or heavy metal levels , which also contribute to ensuring food safety.
