Antibiotic Mixture Containing Narasin at 10% and Diclazuril at 0.2% - Identified as Interban®

European Union Research Findings: JRC, EURL-FA, and Narasin examine Diclazuril, a coccidiostat, in Interban®, used in chickens for fattening and chickens reared for laying purposes

Antibiotic Mixture Containing Narasin at 10% and Diclazuril at 0.2% - Identified as Interban®

In a recent development, an application has been submitted to authorize the use of Interban®, a feed additive, in turkeys for fattening purposes. This application, made under Article 4(1) of the regulation, aims to introduce Interban® into compound feed directly or through premixtures.

Interban® is a feed additive containing 10% narasin and 0.2% diclazuril, two substances that have been widely used in the poultry industry. The proposed content for these substances in compound feed for turkeys is 50 mg and 1 mg per kg, respectively.

The methods of analysis for MRLs (Maximum Residue Limits) for diclazuril in turkey tissues are not specified in the given context. However, for the determination of diclazuril in compound feed, the EU method based on HPLC-UV is recommended for official control. Similarly, for narasin, the AOAC method is not specified for turkey tissues, while the EN ISO 14183 method based on HPLC-PCD-UV-Vis is recommended for official control in chicken tissues.

It's worth noting that the methods of analysis for MRLs for diclazuril in poultry tissues do not need to be evaluated by the EURL (European Union Reference Laboratory) as they are already set by Commission Implementation Regulation (EU) No 1235/2013. On the other hand, the multi-analyte ring-trial validated EN 17299 method is recommended for official control for the determination of narasin and diclazuril in compound feed.

Interestingly, further testing or validation of the methods for turkeys is not mentioned in the given context. This is despite the fact that further testing or validation of the methods is not considered necessary as specified by Article 10 of Commission Regulation (EC) No 378/2005.

It's also important to mention that the MRLs for narasin in chicken tissues are 50 μg/kg, as specified in Commission Regulation (EC) No 885/2010. However, MRLs for narasin in turkey tissues are not specified in the given context.

The application seeks authorization for Interban® not only for use in turkeys but also for chickens for fattening and chickens reared for laying. This indicates a potential broadening of the application's scope, subject to regulatory approval.

As the application progresses through the regulatory process, more information about the submission details, including the identity of the applicant and the date of submission, is expected to be disclosed. Stay tuned for updates on this developing story.
