ReviewCurrent research, regulation, risk, analytical methods and monitoring results for nicarbazin in chicken meat: A perspective review

- Nicarbazin is an anticoccidial widely used as feed additive in poultry industry.
- The maximum residue limits for chicken meat differ among regulatory agencies.
- Chromatography coupled to mass spectrometry is used to quantify nicarbazin residue.
- This review presents the residue monitoring program results in different countries.
- We discuss analytical performance and decision-making.

This review presents up-to-date information about current research on nicarbazin, one of the most used anticoccidials in poultry production. The focus is to elucidate regulation concerning nicarbazin, limits for its residues in food, how maximum residue limits in different countries are calculated regarding edible chicken tissues and the possible implications in human health. Analytical methods to extract and quantify this residue, expressed as dinitrocarbanilide (DNC) are presented and discussed, including qualitative screening and quantitative/confirmatory analytical methods. Monitoring results and occurrence of DNC residues in chicken meat are discussed. Additionally, the causes of eventual chicken meat contamination and possible solutions to reduce or eliminate DNC residue in tissues are also presented. The paper concludes with perspectives, the current state of DNC residue analysis and suggestions for future research, especially considering the gap in the study of residue recycling effect due to continuous chicken litter use.
