“…Typically, pesticide residues in honey occurs when bees in search for food, visit crops that have been treated with various agro-chemicals and/or when beekeepers use chemicals to control bee pests or diseases (Bogdanov 2006). So far, several researchers have reported various residues of pesticides in honey at varying concentrations (De Pinho, et al 2010;Irani 2009;Barganska et al 2013;Blasco et al 2011;Garcia-Chao et al 2010;Herrera et al 2005;Rissato et al 2007;Weist et al 2011;Fontana et al 2010;Kujawski and Namiesnik 2011;Wang et al 2010;Campillo et al 2006;Choudhary and Sharma 2008;Martel et al 2007;Erdogˇrul 2007;Blasco et al 2003) confirming the need to constantly monitor the presence of pesticide residues in honey to assess any potential health risk and to ensure that its quality, whether as food or as a therapeutic, is not compromised. However, to date, only few studies have been carried out to monitor pesticide residues in honey produced from Africa (Eissa et al 2014).…”

Determination of pesticide residues in honey: a preliminary study from two of Africa’s largest honey producers

Background: The presence of pollutants in honey can influence honey bee colony performance and devalue its use for human consumption. Using liquid chromatography tandem mass spectrometry (LC-MS/MS), various clean-up methods were evaluated for efficient determination of multiclass pesticide contaminants in honey. The selected clean-up method was optimized and validated and then applied to perform a preliminary study of commercial honey samples from Africa. Results: The most efficient method was primary-secondary amine (PSA) sorbent which was significantly different from the others (P <0.05; average recovery~94 %) and was applied to analyze 96 pesticide residues in 28 retail honey samples from Kenya and Ethiopia. From our preliminary data, a total of 17 pesticide residues were detected at~10-fold below maximum residue limit (MRL) established for food products except for malathion which was detected at almost 2-fold above its acceptable MRL. Conclusions: A highly efficient approach for determining pesticide residues in honey with good recoveries was developed. All residue contaminants were detected at levels well below their acceptable MRLs except malathion suggesting that the retail honey analyzed is safe for human consumption. Although PSA clean-up method was selected as the most efficient for cleaning honey samples, omitting the clean-up step was the most economical approach with potential applicability in the food industry.

“…Apart from essential minerals, bee pollen may also contain contaminants as it is exposed to different contamination sources in its environment (Bogdanov, 2006;Wiest et al, 2011). The indiscriminate use of pesticides on crops and the industrial contamination of soils, rivers and lakes introduce some heavy metals, harmful to living organisms, into agricultural ecosystems.…”

Essential minerals and inorganic contaminants (barium, cadmium, lithium, lead and vanadium) in dried bee pollen produced in Rio Grande do Sul State, Brazil

et al. 2016

Like other beehive products, such as honey, royal jelly and propolis, bee pollen has attracted great interest because of the health benefits it can provide when consumed. Bee pollen has high contents of sugars and proteins and a low content of lipids, it is also a rich source of vitamins and other bioactive compounds, which makes it an attractive micronutrient supplement. However, few studies have investigated its composition. Therefore, the aim of this study was to characterize the essential minerals and inorganic contaminants present in bee pollen produced at apiaries in Rio Grande do Sul State, Brazil. Inductively Coupled Plasma Dptical Emission Spectrometry (ICP-DES) revealed the presence of 8 essential minerals (calcium, iron, copper, chromium, manganese, molybdenum, phosphorus and zinc) in the 5 analyzed samples; 6 of them were in sufficiently high amounts to meet dietary requirements. Df the 5 inorganic contaminants assessed (barium, cadmium, lithium, lead and vanadium), only cadmium was present at levels over the International Honey Commission's standards. All bee pollen samples showed a high content of the 8 essential minerals. Contamination usually results from the use of pesticides, fertilizers and other chemicals in agriculture; thus, monitoring of its levels must be included in bee pollen analysis.

“…According to available literature data (Kiljanek et al 2016;Wiest et al 2011) and to our best knowledge ), acetonitrile appears to be the most common choice due to its ability to extract analytes with different physicochemical properties, such as their molecular weight, boiling point, or polarity. Since certain compounds are sensitive to pH, formic acid is often added in order to obtain a constant pH value of approx.…”

The analytical tool for analysis of pesticide residues in honey must still be improved. Therefore, a sensitive, selective, rapid, and reliable analytical method for the analysis of pesticide residue belonging to 29 different classes at very low concentration levels was developed. Over 130 insecticides were extracted from the honey matrix using different amounts of sample, concentrations of the extraction solvent, and cleanup sorbents. Acceptable extraction recoveries accounting for matrix effect were obtained using the cleanup sorbent combination chitosan/aluminum oxide/C8 (200/200/200 mg) and 1% FA in ACN. Determinations were made by liquid chromatography-tandem mass spectrometry (LC-MS/MS). For most compounds, the recoveries range from 70 to 120%, with relative standard deviations < 20%. Linear correlation coefficients (r2) were higher than 0.99 at concentration levels of 0.001-0.100 mg kg−1. A positive matrix effect was observed for up to 95% of organophosphates and 43% of pyrethroids and a negative effect for 37% of neonicotinoids. This work showed that the presented method is convenient and reliable for quick monitoring of insecticides in honey samples.
