  • Clothianidin residues in green bean, pepper and watermelon crops and
           dietary exposure evaluation based on dispersive liquid-liquid
           microextraction and LC–MS/MS
    • Abstract: Abstract We developed an analytical method for quantifying clothianidin residues in green bean, pepper and watermelon crops using dispersive liquid-liquid microextraction (DLLME) and liquid chromatography-tandem mass spectrometry; this method was more rapid, sensitive and simple than QuEChERS sample preparation. Method validation indicated that the recovery for clothianidin was 80.8–93.1%, intra-day and inter-day repeatability ranged from 3.32 to 6.11% and 7.77 to 14.74%, respectively, limits of detection ranged from 0.64 to 0.74 µg/kg, and limits of quantification were 2.13–2.47 µg/kg. Matrix-matched calibration was used to compensate for matrix effects. Following application of the recommended dose in field trials, clothianidin dissipation followed first-order kinetics with half-lives of 1.9, 2.07, and 1.87 days in green bean, pepper, and watermelon crops; respective waiting periods of 5.76, 6.18, and 7.87 days after application are suggested for safe consumption. This study indicates the application of clothianidin presents no significant health risk to Egyptian consumers.

  • Standard safety policy: a retrospect of the Korean chicken egg crisis in
           2017
    • Abstract: Abstract On August 14, 2017, a report released by the Ministry of Agriculture, Food, and Rural Affairs confirmed the presence of pesticides in chicken eggs in South Korea. The literature has identified various causes for the crisis, such as the lack of criteria for permissible amounts of residual pesticides, and dichotomized management and supervision systems. This study investigated current laws and enactments relevant to South Korea’s 2017 crisis of pesticide-contaminated eggs, seeking to extract applicable safety standards. Of the 12 laws directly related to eggs, eight contained a combined total of 19 safety standards. The main problems of these standards include the lack of criteria to regulate permissible amounts of residual pesticides, the lack of standardized countermeasures against residual chemicals, conflicting standards between higher-ranking and lower-ranking legal norms, and confusing misuse of terminology. It is suggested that these problems in egg-related safety standards can be addressed by South Korea adopting the internationally recognized Codex Alimentarius standard, with strengthened application of stricter administrative measures exceeding the Maximum Residue Levels in the field, using unified terminology. Thus, the present study aims to investigate the 2017 crisis to extract safety standards from the law and analyze related problems. The study also makes suggestions to improve applicable safety standards in the hope of preventing the recurrence of similar crises.

  • Ciguatera fish poisoning outbreaks from 2012 to 2017 in Germany caused by
           snappers from India, Indonesia, and Vietnam
    • Abstract: Abstract Ciguatera fish poisoning (CFP) is the most common fish intoxication worldwide. It is caused by ciguatoxins produced by tropical, benthic and epiphytic microalgae in the genera Gambierdiscus and Fukuyoa. These potent neurotoxins accumulate in the food chain reaching their highest concentration in tropical fish and invertebrates. In addition to gastrointestinal symptoms, cold allodynia and other neurologic signs are characteristic of ciguatera. In continental Europe, most cases were linked to vacation trips to tropical areas. The first outbreak in Germany was documented in 2012. The objective of this study is to document ciguatera outbreaks in Germany associated with imported tropical fish. Reports by physicians and the German Public Health Service to the German Federal Institute for Risk Assessment (BfR) were collated and evaluated for symptoms consistent with CFP. Data of molecular identification of the fish, as well as toxicity data from meal and batch remnants, were provided where possible to substantiate ciguatoxins as the causative agent. A series of six outbreaks were registered in Germany between 2012 and 2017. Fourteen of the 65 patients were hospitalised. All German outbreaks were caused by snappers (Lutjanidae) imported from India, Indonesia and Vietnam. Though ciguatera remains a rare disease in Germany, physicians should be aware of it, and appropriate preventive strategies should be established. Reporting of CFP in fish importing countries may contribute to improve regional public health strategies in the affected fish exporting countries and reduce chances of exporting ciguatoxic fish. This article proves that fish from the Indian Ocean can cause ciguatera, which has been poorly documented previously.

  • Prevalence of β-haemolytic multi-drug resistant E. coli in cow and
           camel milk in Kenya
    • Abstract: Abstract The aim of this study was to find the prevalence of β-haemolytic Escherichia coli in milk, as well as their sources, and their sensitivity to antibiotics. E. coli was isolated from samples of cow and camel milk, cow and camel udder surfaces, and milking persons’ hands. The organisms were identified using API20E biochemical kit. Haemolytic activity was tested on 7% defibrinated sheep blood agar while antibiotic sensitivity was tested using the Kirby-Bauer disc diffusion method. The prevalence of β-haemolytic isolates from cow and camel milk was 25% and 32% respectively. None of the isolates from the udder swabs, the milking persons’ hands, or water was β-haemolytic. In cow milk, the prevalence of isolates resistant to Ampicillin, Cefotaxime, and Cefepime was 25, 37.5 and 12.5% respectively, while in camel milk it was 52.4, 23.8 and 28.6% respectively. Prevalence of β-haemolytic and multidrug resistant isolates to the three antibiotics was 12.5% for cow milk and 19% for camel milk. None of the isolates was resistant to Ciprofloxacin, Piperacillin/Tozobactam, Amikacin, and Imipenem. The prevalence of E. coli resistant to Cefotaxime and Cefepime indicates growing resistance of the microorganisms to drugs that are supposed to be effective against them. The presence of β-haemolytic isolates in milk and their absence on the animals’ udder surface and hand swabs could indicate their better survival in the udder from which they are shed into the milk. This is a public health concern especially for pastoral communities who have a preference for consumption of raw milk.

  • Potential operator dermal exposure during foliar indoor application: a
           comparison between knapsack, trolley sprayer and lance equipment
    • Abstract: Abstract In accordance with the risk assessments required in the framework of Regulation (EC) no. 1107/2009, operator exposure must be determined taking into account the material and the conditions of use. However, the existing European Union harmonised predictive model (EFSA in EFSA J 12(10):3874, https://doi.org/10.2903/j.efsa.2014.3874, 2014) has shortcomings, especially the lack of operator exposure data during applications in greenhouses. The aim of this study, performed in France, was to measure levels of operator dermal exposure in greenhouses where knapsack or trolley sprayers are used, and to evaluate the protection provided by dermal personal protective equipment under field conditions. The potential dermal exposure on the body and head excluding the hands, and on the hands ranged from 936 to 14,052 µg/day, and from 173 to 1762 µg/day, respectively. The transfer factors provided by the personal protective equipment (certified coverall and gloves) were low, 2.3% and 0.8% (75th percentile), respectively. When exposure levels measured during the spraying phase of the experimental exposure study were compared to those calculated using the new greenhouse model (Project Report, German Federal Institute for Risk Assessment (BfR), Berlin, http://www.bfr.bund.de/cm/350/joint-development-of-a-new-greenhouse-agricultural-operator-exposure-model-for-hand-held-application.pdf, Accessed 26 June 2018, 2015), the model prediction using the dense culture scenario for potential body and head exposures fits well with the levels of exposure measured in the experimental study. The results of this experimental greenhouse exposure study could be used to increase the robustness of operator exposure estimates provided by the Greenhouse Agricultural Operator Exposure Model (Project report-BfR 2015) in the context of pesticide applications in greenhouses.

  • Method validation and evaluation of household processing on reduction of
           pesticide residues in tomato
    • Abstract: Abstract Metalaxyl and chlorpyriphos are widely used pesticides around the world. The purpose of this study was to evaluate validation parameters, matrix effect (ME %), reduction behavior, processing factor (PF) and estimate the behavior of metalaxyl and chlorpyriphos in tomato fruit samples. “Quick, Easy, Cheap, Effective, Rugged, and Safe” (QuEChERS) extraction and gas chromatography coupled to mass spectrometry (GC/MS) were used for the analysis. Results showed successful trends by evaluating validation parameters [selectivity, linearity, limits of detection (LOD), limits of quantification (LOQ) and precision]. The correlation coefficients were > 0.99; the LOD for metalaxyl ranged from 0.01 to 0.003 mg/kg and the LOQ for chlorpyriphos ranged from 0.03 to 0.009 mg/kg. The matrix effect (ME %) of metalaxyl was found to exhibit a medium matrix effect while for chlorpyriphos no matrix effect was seen. Recovery (70–120%) and precision (RSD < 20%) for both pesticides metalaxyl and chlorpyriphos were within the satisfactory ranges recommended by the European Commission. The PF was generally < 1 (ranged between 0.34 and 0.98). Except when using washing solutions, metalaxyl PFs were > 1. The highest reduction rate was achieved by sonication treatments which could effectively remove chlorpyriphos residues spiked in tomato matrices rather than the metalaxyl residues. On the other hand, washing treatments were less efficient in removing metalaxyl residues from tomato samples. Overall, any one of these processes can contribute substantially to reduce consumer exposure to pesticides residues in tomatoes.

  • Bacteriocinogenic properties and safety evaluation of Enterococcus faecium
           YT52 isolated from boza, a traditional cereal based fermented beverage
    • Abstract: Abstract The objectives of this study were to characterize the antibacterial substances produced by Enterococcus faecium YT52 isolated from boza, and to evaluate the safety of this strain. E. faecium YT52 inhibits various Gram-positive bacteria, including foodborne pathogens such as Listeria monocytogenes and Bacillus cereus. The manner of action of its antibacterial activity, using proteolytic enzymes, indicate that it produces a bacteriocin. The bacteriocin producing isolate E. faecium YT52 was identified using 16S rRNA gene homology and species-specific polymerase chain reaction (PCR) analysis. The bacteriocin was found to be heat stable and active under both acid and alkaline conditions. The bacteriocin showed primary metabolite kinetics and a bactericidal mode of action against L. monocytogenes. Although enterocin A, B and X genes were detected in E. faecium YT52 by PCR, only one active peptide band (~ 5.5 kDa) with a molecular weight similar to enterocin B was identified by tricine–SDS-PAGE analysis. A safety evaluation of E. faecium YT52 indicated that it is nonhemolytic, gelatinase-negative, and susceptible to clinically relevant antibiotics such as ampicillin, tetracycline and vancomycin. It contains a small number of virulence factors (efaAfm, silent gelE) and antibiotic resistance genes (ermB, tetM, tetL). In conclusion, bacteriocinogenic E. faecium YT52 was found to have a low risk profile, and it may be potentially valuable as a protective culture in the food industry.

  • Insecticidal and repellent effects of essential oils from leaves of Hyptis
           suaveolens and Ocimum canum against Tenebroides mauritanicus (L.) isolated
           from peanut in post-harvest
    • Abstract: Abstract The present work aims to evaluate the insecticidal and repellent effects of essential oils from fresh leaves of Hyptis suaveolens and Ocimum canum against Tenebroides mauritanicus (L.) (Coleoptera: Tenebrionidaea) isolated from peanut in post-harvest in Benin. Chemical analysis of essential oils by GC and GC-MS indicated that, in the volatile extracts, different groups of terpene and terpenoid were present. The results of contact toxicity tests indicated that at a concentration of 0.5 µl of essential oil/g of peanut the mortality rate of Tenebroides mauritanicus (L.) is 100% after 24 h for the essential oil of Hyptis suaveolens, while it is still at 20% for the essential oil of Ocimum canum. Results also indicated that Hyptis suaveolens oil has a high repellent activity, when compared to the essential oil of Ocimum canum. This essential oil with high repellent and insecticidal properties represents a novel approach in the protection of grains against T. mauritanicus and the reduction of post-harvest losses.

  • Estimation of metal residues in Oreochromis niloticus and Mugil cephalus
           intended for human consumption in Egypt: a health risk assessment study
           with some reduction trials
    • Abstract: Abstract Fish, including tilapia (Oreochromis niloticus) and mullet (Mugil cephalus), is a major source of essential amino acids, omega-3 fatty acids, vitamins and minerals. However, fish as aquatic organism is highly exposed to environmental pollutants such as heavy metals. This study investigated the residual concentrations of lead (Pb) and cadmium (Cd) as toxic metals, and copper (Cu) and zinc (Zn) as essential trace elements in tilapia and mullet intended for human consumption in six major cities in Egypt. Correlation analysis between metal content and fish biometrics was done. Fish is heat-treated before consumption in Egypt; therefore, the effect of heat treatment, either alone or in combination with ascorbic acid 2%, on the residual content of heavy metals in tilapia was investigated. Dietary intake and health risk assessment for the measured metals were calculated. The achieved results indicated higher contents of Pb and Cd in the examined fish compared to the established maximum residual concentrations. Immersion of tilapia in ascorbic acid 2% followed by pan-frying significantly reduced metal load in the fish muscle; however, grilling of fish increased the metal content, probably due to water evaporation and concentration of metals in the fish muscle. Estimation of dietary intakes of such metals through fish consumption indicated potential exposure of Egyptians to the adverse effects of Pb and Cd. At the same time, tilapia and mullet can partially provide humans with their needs of the essential trace elements (Cu and Zn). In conclusion, consumption of contaminated fish with Pb and Cd may constitute potential health hazards for people heavily consuming such fish. Immersion of fish in ascorbic acid 2% for 30 min followed by pan-frying is recommended for reduction of metal load in the fish. Continuous monitoring programs for toxic metal contents in fish are highly recommended.

  • Biofilm-formation by drug-resistant Staphylococcus aureus from cow milk
    • Abstract: Abstract The present study aims to quantify biofilm formation and determine the drug resistance profile of Staphylococcus aureus isolated from raw, pasteurized and ultra-high temperature (UHT) milk. Detection of S. aureus was made in 90 cow milk samples (30 raw, 30 pasteurized and 30 UHT). Biofilm biomass quantification was performed in 96-well polystyrene plates using the crystal violet technique. The resistance profile was determined by the disc-diffusion test. S. aureus was detected in 24.4% (22/90) of milk samples, with the highest prevalence in pasteurized milk. Biofilm production was observed in 100% of the S. aureus isolates from pasteurized and UHT milk, and in 81.8% of the strains from raw milk. Biofilm production by S. aureus drug-resistant strains was detected in 46.7% (14/30) of the isolates. In order to mitigate this problem, it is recommended to apply appropriate hygiene practices along the milk production chain.

  • Exposure of consumers and farmers to organophosphate and synthetic
           pyrethroid insecticides in Northern Thailand
    • Abstract: Abstract Organophosphate and pyrethroid insecticides are used for controlling residential and agricultural insect pests and disease-carrying vectors in Thailand especially in the northern region. Chiang Rai and Nan Provinces are well known for agricultural production. The aim of the present study was to assess the level of exposure to organophosphate and pyrethroid insecticides in 51 consumers and 49 farmers living in Chiang Rai and Nan Provinces by monitoring the urinary metabolites 6-dialkylphosphates (DAPs) and 3-phenoxybenzoic acid (3-PBA) as biomarkers of exposure to organophosphates and pyrethroids. The results showed at least one metabolite was present in all subjects indicating that consumers and farmers were exposed to these pesticides. Concentrations of organophosphate and pyrethroid metabolites in consumers and farmers were similar except diethylthiophosphate which was significantly higher in farmers. Diethyldithiophosphate and 3-PBA concentrations were significantly different between the group who had reported using and not using pesticide in their house.

  • Characterization of retroviral vector derived DNA-isoforms by PCR and
           sequencing
    • Abstract: Abstract For the analytical surveillance of genetic engineering operations suitable methods for characterization of used (recombinant) cell lines and used transfer vector plasmids are needed. The purpose of the described method is the identification of retroviral DNA-isoforms based on lenti-or gammaretrovirus (HIV-1 or MLV). The primers, used in an optimized touch-down PCR protocol, specifically amplify transfer-vector encoded vector genomes and proviruses integrated into stably transduced vertebrate cell lines, distinguishing them from the background of endogenous retroviral sequences. The resulting PCR products were isolated by preparative agarose electrophoresis and subsequently used for sequence identification by Sanger sequencing. In addition, the amplification and sequencing of PCR products corresponding to the HIV-1- and MLV-based vector-genomes was successful from residual transfer vector plasmids in cell culture supernatants and basic polyethylene glycol-precipitated vector preparations. The methods were validated using 19 samples (cell lines, plasmids and viral vector preparations). No false-positive PCR results were observed, while both retroviral DNA-isoforms were detected with the respective assay. The successful implementation in routine analysis is presented using two routine samples.

  • The effect of pumpkin flour on quality and acoustic properties of extruded
           corn snacks
    • Abstract: Abstract Significant amounts of minerals, vitamins, carotenoids and other bioactive substances, as well as documented health-promoting activity, make pumpkin flour (PF) an interesting food additive. In this article, the influence of PF addition (2% and 4%) on quality, acoustic and textural properties, colour, potential renal acid load (PRAL) and consumer acceptance of extruded corn snacks was evaluated. The results showed that PF addition can be used for production of sensorily attractive extrudates with lowered acidity. However, changes in the general characteristics of extrudates were observed. The expansion ratio and water solubility index decreased, while the bulk density and water absorption index increased. Changes of colour were observed as well. PF addition resulted in significantly decreased hardness and breaking force index. Moreover, the acoustic properties (total loudness, crackliness, crispness and crunchiness) of the extrudates produced with PF were different from the control. The total loudness, crackliness, crispness as well as crunchiness in extrudates enriched with PF significantly decreased (p < 0.005) with increasing percentage of PF in the product. Nevertheless, the results of the consumer study indicated that the addition of PF improved the taste and appearance of extrudates, thus increasing the overall acceptability of the final product.

  • Terephthalic acid determination in mineral water stored in PET bottles
           using a novel magnetic dispersive micro solid-phase extraction followed by
           high-performance liquid chromatography
    • Abstract: Abstract Contamination in food from packing material can occur in trace quantities. However, the migration of substances from food packing material needs to be evaluated to ensure that the levels are not toxic. Terephthalic acid (TA) can migrate into mineral water stored in polyethylene terephthalate (PET) bottles and pose a wide range of health hazards depending on the toxicological threshold. A magnetic dispersive micro solid-phase extraction (MDMSPE) associated with HPLC–UV was implemented to determine TA levels in mineral water from PET bottles. The calibration curve was constructed with the correlation coefficient up to 0.99 over the concentration range of 50–500 ng/mL. The recoveries ranged from 98 to 105% and the relative standard deviation (RSD) and accuracy was < 8%. This method is quick, sensitive, simple and accurate, and could be applied to determine TA in water stored in PET bottles in a short analysis time.
