Evaluation of ELISA kits for the screening of four nitrofuran metabolites in aquaculture products according to the European guideline for the validation of screening methods.

The administration of nitrofurans to livestock to treat or prevent animal diseases has been banned in the EU for the production of food of animal origin. The corresponding marker residues are tissue-related metabolites AMOZ, AHD, SEM, and AOZ. The MRPL (minimum required performance limit)/RPA (Reference point for action) was set at 1 µg kg in the EU.

Multiplex immunoassay based on biochip technology for the screening of antibiotic residues in milk: validation according to the European guideline.

The Infiniplex for milk® (IPM) kit is a quick method for the simultaneous and qualitative detection of more than 100 molecules including antibiotic residues, mycotoxins, anti-inflammatories and antiparasitic drugs into a single test that does not require milk treatment. The IPM® kit was validated according to the European decision EC/2002/657 and according to the European guideline for the validation of screening methods (2010). Our validation was focused only on antibiotic residues.

Strategies for the screening of antibiotic residues in eggs: comparison of the validation of the classical microbiological method with an immunobiosensor method.

Efficient screening methods are needed to control antibiotic residues in eggs. A microbiological kit (Explorer® 2.0 test (Zeu Inmunotech, Spain)) and an immunobiosensor kit (Microarray II (AM® II) on Evidence Investigator™ system (Randox, UK)) have been evaluated and validated for screening of antibiotic residues in eggs, according to the European decision EC/2002/657 and to the European guideline for the validation of screening methods.

Evaluation and validation of a multi-residue method based on biochip technology for the simultaneous screening of six families of antibiotics in muscle and aquaculture products.

The Evidence Investigator™ system (Randox, UK) is a biochip and semi-automated system. The microarray kit II (AM II) is capable of detecting several compounds belonging to different families of antibiotics: quinolones, ceftiofur, thiamphenicol, streptomycin, tylosin and tetracyclines. The performance of this innovative system was evaluated for the detection of antibiotic residues in new matrices, in muscle of different animal species and in aquaculture products.

Evaluation and validation of biochip multi-array technology for the screening of six families of antibiotics in honey according to the European guideline for the validation of screening methods for residues of veterinary medicines.

The main chemicals used against varoa are acaricides, and the antibiotics used for the control of bee bacterial diseases are mainly tetracyclines, streptomycins, sulfonamides and chloramphenicol. No maximum residue limits (MRLs) have been set for any antibiotics in honey. Therefore, in the European Union, minimum recommended concentrations (RC) for the analytical performance of methods to control a certain set of these non-authorised chemicals in honey were published by the European Union Reference Laboratory (EU-RL) in 2007.

Validation of two ELISA kits for the screening of tylosin and streptomycin in honey according to the European decision 2002/657/EC.

Antibiotics are mixed with the food of bees to fight against diseases. No maximum residue limits have been set for honey. Recommended concentrations (RCs) have been published by European Union Reference Laboratories for tylosin and streptomycin.

Validation of a Biacore method for screening eight sulfonamides in milk and porcine muscle tissues according to European decision 2002/657/EC.

Sulfonamides are commonly used for prophylactic or therapeutic purposes in veterinary medicine. A maximum residue limit (MRL) for sulfonamides has been set at 100 microg/kg in milk and muscle. A multisulfonamide antibody was used for the development of 2 different Biacore protocols, one for the screening of milk samples, the other for muscle samples.
