Overview
ISO 23851:2026 specifies an analytical method using liquid chromatography tandem mass spectrometry (LC-MS/MS) for the determination of marker residues of nicarbazin, specifically 4,4-dinitrocarbanilide, in chicken tissue and eggs. This international standard, developed by ISO Technical Committee 34, Subcommittee 6, is designed for application to a range of chicken tissue matrices-including muscle, liver, and kidney-as well as whole eggs.
Nicarbazin is a common veterinary drug used in poultry production as a coccidiostat. Accurate quantification of nicarbazin residues in food products is essential for food safety, regulatory compliance, and international trade. ISO 23851:2026 enables laboratories to consistently determine these residues and supports efforts to monitor and control veterinary drug residues in poultry products.
Key Topics
Applications
ISO 23851:2026 provides practical value to a variety of stakeholders in the food and animal products industry. Its applications include:
-
Regulatory Compliance
- Ensures adherence to food safety standards by accurately monitoring nicarbazin residue levels in poultry products
- Facilitates compliance with domestic and international residue limits
-
Food Safety Monitoring
- Used by testing laboratories, quality control departments, and inspectors to verify the safety of chicken and egg products
- Supports public health initiatives by enabling detection of veterinary drug residues
-
International Trade
- Harmonizes laboratory practices for importing and exporting countries, reducing trade barriers associated with residue testing in poultry products
-
Research and Development
- Supports academic and private sector research focused on residue analysis, method validation, and the effects of veterinary drugs in food animals
-
Risk Assessment
- Provides reliable data for risk assessment studies evaluating human exposure to veterinary residues in foods of animal origin
