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 now – keeping in mind the fact that we are still fighting against a …
The aim of this work was to develop an analytical method for simultaneous assay of residues of two families of antibiotics, and three pesticides, in honey. The assays involved a mixture of five tetracyclines, four sulfamides, and the pesticides coumaphos, carbendazim, and amitraz (two metabolites). All the compounds were extracted …
Mr. Sashi Kumar with his branded honey bottles in his lab. Income generation is important for any agricultural activity. What farmers need is a remunerative income (not minimum income) for their produce, and honeybee rearing fits the slot too well. It has been proven to increase a farmer's income by …
Honey, being a natural product manufactured by honey bees is considered to be free from any extraneous material. The over-reliance on pesticides caused several environmental problems including pesticide residues in food. This constitutes a potential risk for human health, because of their sub acute and chronic toxicity. Therefore this study …
frequent, uncontrolled fires are threatening the Gautala Autramghat Wildlife Sanctuary in Maharashtra's Aurangabad and Jalgaon districts. About 40 incidents of fire have been reported from the 260 sq km-sanctuary since December 2007, destroying about 230 hectares (ha). "Last year, this was just 40 ha. This may increase as summer sets …
Honey collection in Sundarban begins Tapos Kanti Das . Khulna Honey collection in Sundarban began on April 1 and the Sundarban forest division has started distribution permits for honey collection. The department, however, imposed a ban on honey collection from the east division of the forest. Honey collection in Sundarban …
Residue levels of drugs, pesticides and heavy metals in food commodities, is becoming a major concern for food regulators all over the world. Since the residue levels cannot be changed drastically through various production techniques and because it is necessary to provide safe food to the consumers, it is essential …
A multiclass method has been developed for the determination and confirmation in honey of tetracyclines (chlortetracycline, doxycycline, oxytetracycline, and tetracycline), fluoroquinolones (ciprofloxacin, danofloxacin, difloxacin, enrofloxacin, and sarafloxacin), macrolides (tylosin), lincosamides (lincomycin), aminoglycosides (streptomycin), sulfonamides (sulfathiazole), phenicols (chloramphenicol), and fumagillin residues using liquid chromatography tandem mass spectrometry (LC-MS/MS). Erythromycin (a macrolide) …
A method making use of turbulent flow chromatography automated online extraction with tandem mass spectrometry (MS/MS) was developed for the analysis of 4 quinolones and 12 fluoroquinolones in honey. The manual sample preparation was limited to a simple dilution of the honey test portion in water followed by a filtration. …
A multi-screening approach for monitoring potential chemical contaminants in honey by liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) has been developed. A total of 42 veterinary drugs (5 tetracyclines, 7 macrolides, 3 aminoglycosides, 8 beta-lactams, 2 amphenicols and 17 sulfonamides) were surveyed with the ultimate goal of unambiguously confirmed and …
albert einstein is said to have said: "If the honeybee becomes extinct, mankind will follow within four years.' The physicist wasn't entirely off the mark
Two liquid chromatography mass spectrometric techniques, i.e. ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-Tof MS) and high-performance liquid chromatography/tandem mass spectrometry (LC/MS/MS), were used for quantification, confirmation or identification of six macrolide antibiotic residues and/or their degradation products in eggs, raw milk, and/or honey. Macrolides were extracted from food samples …
British beekeepers have been confronted by a mysterious disease that has already affected the us and many European countries. Known as colony collapse disorder (ccd), it is possibly the most serious disease faced by bees. According to the uk's National Bee Unit, a branch of the Department for Environment, Food …
In Poland honey has never been included in regular pesticide residues controls. Because no maximum residues levels (MRLs) have been established for pesticides in honey it is very hard to evaluate the contamination of honey with pesticides and the possible damage to human health. This study was carried out in …
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). A poly(methacrylic acid?ethylene glycol dimethacrylate) monolithic capillary column was selected as the extraction …
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 researchers at the University of California (uc, Berkeley, and uc Davis. "Until now, we've thought that honeybees …
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. The method was validated according to …
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. Residues of the antibiotics were determined using liquid chromatography/electrospray …
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. The environmental contamination by persistent organochlorine pesticide OCPs) residues has been widely documented in several countries, such as …
