Laboratory results of honey testing
It is a food fraud more nefarious and more sophisticated than what we found in our 2003 and 2006 investigations into soft drinks; more damaging to our health than perhaps anything that we have found till

Chloramphenicol extraction from honey, milk, and eggs using polymer monolith microextraction followed by liquid chromatography
A rapid confirmatory method for monitoring chloramphenicol (CAP) residues in honey, whole milk, and eggs is presented. This method is based on the polymer monolith microextraction (PMME) technique and high-performance liquid chromatography (HPLC)?electrospray ionization mass spectrometry (MS).

Interaction of domestic, wild honeybees results in efficient sunflower pollination
when domesticated honeybees interact with wild native bees, they are up to five times more efficient in pollinating sunflowers than when native bees are not present, claims a study by a pair of

Validation of an analytical methodology for determination of oxytetracycline and tetracycline residues in honey by HPLC
An analytical method for the determination of OTC and TC residues in honey was developed. Sample treatment involves an extraction in EDTA-McIlvaine buffer, followed by a solid-phase cleanup step. With regard to the cleanup procedure, different SPE cartridges were evaluated and the results presented.

Determination of lincomycin and tylosin residues in honey by liquid chromatography/tandem mass spectrometry
A simple and rapid analytical method was developed for the determination of lincomycin and tylosin residues in honey as part of field studies examining the efficacy and target animal safety of these antibiotics to control American foulbrood disease in honey bees.

Determination of organochlorine pesticide residues in honey from the central zone of Portugal & the Valencian community of Spain
The occurrence of organochlorine compounds in the food chain has already been reported in several studies. This class of organic compounds constitutes one of the most important groups of dangerous organic contaminants.

Confirmatory determination of six penicillins in honey by liquid chromatography/electrospray ionization-tandem mass spectrometry
A confirmatory method for 6 penicillin antibiotics (amoxicillin, ampicillin, penicillin G, oxacillin, cloxacillin, and dicloxacillin) in honey is presented that allows determination and confirmation of identity of the antibiotics at trace levels.
-
Determination of five macrolide antibiotic residues in honey by LC-ESI-MS and LC-ESI-MS/MS
Liquid chromatography?electrospray ionization mass spectrometry methods (LC-ESI-MS and LC-ESI-MS/MS) for the determination of five macrolide antibiotics including spiramycin, tilmicosin, oleandomycin, erythromycin, and tylosin in honey are presented.
-
Assessment of pesticide residues in honey samples from Portugal and Spain
Fifty samples of honey collected from local markets of Portugal and Spain during year 2002 were analyzed for 42 organochlorine, carbamate, and organophosphorus pesticide residues.

Trace level quantification of streptomycin in honey with liquid chromatography/tandem mass spectrometry
Streptomycin belongs to the group of aminoglycoside antibiotics. It was utilized in apiculture to protect bees against a variety of bee diseases. It was the aim of this study to develop a highly sensitive LC/MS/MS method, which could be validated, for the quantitative determination of streptomycin in honey.
