The distribution of bio-aerosols in diverse environments is a major concern to aero-microbiologists and environmentalists in general. The study evaluated the mycological quality of the air environment around a market along East-West road in Bayelsa State, Nigeria. Petri dish containing sterile Potatoes dextrose agar was exposed for 10 minutes around a market along East-West road in Bayelsa state at a height of 1 meter. The density and diversity of the isolates were determined following standard mycological procedures. The density of the fungi–aerosols ranged from 0.0073 - 0.0268 CFU/min-m2 and was statistical higher in dry (November, January and March) compared to wet (May, July and September) seasons, an indication of seasonal influence. A total of 11 fungi species were recorded with 5 predominant species viz Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Fusarium chlamydosporum and Penicillium species (occurring in ≥66.67% of the study months), while 6 species, Aspergillus lentulus, Aspergillus nidulans, Aspergillus terreus, Cladosporium cladosporioides, Microsporum canis and Mucor species are opportunistic occurring in ≤50% of the study months). Most fungi species are found in the soil, and are known to produce toxins and cause diseases. There is need for a concerted effort by local government authorities via its agencies to sensitize people on proper hygiene practices around markets.

The present investigation was focused on the study of the chemical composition variability and biological activities of the essential oils from Clinopodium nepeta subsp. nepeta and subsp. glandulosum. Essential oils extraction was performed using hydrodistillation and the separation of the constituents was carried out by gas chromatography coupled with mass spectrometry (GC-MS). Antifungal activities were tested against Aspergillus flavus, Aspergillus terreus, Microsporum canis, Microsporum gypseum, Trichophyton mentagrophytes, and Candida albicans. Toxicity and repellency were evaluated against the stored product pests Tribolium confusum and Sitophilus zeamais. Both essential oils were characterized by a high content of oxygenated monoterpenes. Piperitone ranks first in the subspecies nepeta and piperitenone oxide is the dominant constituent in the subspecies glandulosum. All tested samples displayed noteworthy antifungal properties, with the highest activity observed for the essential oil of C. nepeta subsp. glandulosum, collected in Béni-M’tir, against T. mentagrophytes (MIC = 40 µg/mL). The essential oil samples of C. nepeta subsp. glandulosum were strongly repellent to the insect species (PR > 80%, after 2h) and highly toxic to S. zeamais reaching 97.5%–100% mortality after 24 h of exposure. In conclusion, this study showed considerable intra-specific changes in the quality of C. nepeta essential oils, which is reflected in different rates of antifungal and insecticidal activity.

India has the highest proportion of adolescents and the highest adolescent pregnancy and childbirth rate in the tribal segment of the population. Very few studies have focused on the use of sanitary pad and quality of health care as menstrual hygiene practices. The data was collected among ‘Bharia’ women who identified as one of the particularly vulnerable tribal groups (PVTGs) in Madhya Pradesh. Towards comparing the use, source, and components of menstrual hygiene practices among adolescents and adult mothers, the sample included adolescent (10-19 years) and adult women 20-49 years of age. The relevant information was collected by trained female investigator with designed questionnaire from the respondents. Findings revealed that only 22.7% women are using sanitary pad during menstruation period in the studied tribe. It was seen the use of this absorbent (sanitary pad) for menstrual hygiene among the adolescents were found significantly higher (37.5%) than that of adult women (14.3%), whereas, the use of old cotton was found significantly higher (78.6%) among adult women. Awareness on menstrual hygiene about 50% adolescents and 64% adult women believed it is a curse of God. About 25% adolescents and 21.4% adult women believed menstruation is a natural process. The tribe has underprivileged menstrual hygiene practices owing to low awareness, illiteracy, and poverty. The special IEC education campaign with suitable strategy can be forced to optimum hygiene practices.

This third edition of the Anchor Bible Book Of Job (Volume 15 in the series) contains numerous new, revised or augmented notes. Of special interest is the inclusion of readings from the earliest translation of the Book Of Job, the recently published Targum (Aramaic translation) recovered from Cave XI of Khirbet Qumran, in the Judean Wilderness near the Dead Sea, perhaps the version which was suppressed by Rabbi Gamaliel. The Book Of Job is one of the indisputably great works of world literature. The story is well-known: a prosperous and happy man, distinguished for rectitude and piety, falls victim to a series of catastrophes. And the occasion (if not the reason) for these undeserved calamities: Satan's challenge to Yahweh to test the sincerity of Job's faith. It is by now proverbial to refer to the patience of Job. Yet this traditional image derives only from the Prologue and the Epilogue of the book. But the Job who confronts us in the long middle section is anything but patient. His outcries against God raise the question of theodicy, or divine justice, which occupies the greater portion of Job's Dialogue with his comforters. But it is inevitably as literature that Job must be read and enjoyed. This translation is marked by a concerted effort to capture as much as possible the poetic and metrical characteristics of the original Hebrew: the result is a version notable for its accuracy and directness. The experience of reading the Book Of Job in this translation, then, is to rediscover an exceedingly eloquent masterpiece. In the terse, rhythmic quality of the translation, the incisive comprehensiveness of the introduction and notes, Job maintains the high standard of scholarship, literateness, and readability established in The Anchor Bible.

Abstract Background If hygiene practices along the beef processing nodes at small and medium enterprise (SME) slaughter houses and butcheries are not observed, they may pose a health risk due to microbial contamination. In SME slaughterhouses and butcheries, the risk may be higher due to transmission of foodborne pathogens. This study determined the hygienic practices and microbial quality risk among meat handlers (MH) in SME slaughterhouses and butcheries. Methods Assessment of microbiological quality of beef was carried out at slaughter houses and butcher shops in the districts of Western, Central and Eastern regions of Uganda. A cross sectional study was conducted from June 2017 to January 2018 using observation checklists to record unhygienic practices among the various actors. Microbial load at slaughter and butchery was determined from a total of 317 swab samples collected from carcass, tools, protective clothing and hands of meat handlers. The microbiological quality of beef was evaluated using standard microbiological methods. The samples were inoculated into differential and selective media. Results Butcheries had the highest microbial load on beef carcass ranging from 4.76 log 10 cfu/cm 2 to 7.90 log 10 cfu/cm 2 Total Viable Counts (TVC) while Total Coliform Counts (TCC) ranged from 1.42 log 10 cfu/cm 2 to 3.05 log 10 cfu/cm 2 , E. coli ranged from 0.68 log 10 cfu/cm 2 to 1.06 log 10 cfu/cm 2 and Staphylococcus aureus ranged from 3.25 log 10 cfu/cm 2 to 4.84 log 10 cfu/cm 2 . Salmonella was absent in all the samples analysed. Results of overall microbial quality of beef in Uganda indicated that only TCC (1.60±0.26 log 10 cfu/cm 2 ) of the beef carcass samples at slaughter houses was not significantly above the safe level (p = 0.693). Overall microbial load (TVC, TCC, E. coli and S. aureus ) at butcheries were significantly (p < 0.05) above the safe level. Butcheries of Mbale district had the highest percentage (70%) of beef carcass samples above the TCC safe levels whereas butcheries of Mbarara district had the highest percentage (40%) of beef carcass samples above the E. coli safe levels. TVC from hands and clothes at butchery across the three study districts varied significantly (p=0.007) with the highest counts (7.23 log 10 cfu/cm 2 ) recorded from personnel clothes and lowest (5.46 log 10 cfu/cm 2 ) recorded from hands. On the other hand, swab samples picked from chopping board and working table at the butchery did not show significant variation in TVC, TCC, E. coli and S. aureus microbial loads across the three study districts. Conclusion Hygienic handling of carcasses after slaughter is critical in preventing contamination and ensuring meat safety in informal meat trading sectors in Uganda. Handling practices of beef at Ugandan slaughterhouses and butcheries are not hygienic hence not up to standard and they contribute to microbial contamination of beef posing a risk to consumers. The distribution stage is the most critical period, during which the quality of meat can easily be compromised.

Le Mashanza est un fromage frais traditionnel produit à l’Est de la RDC particulièrement au Sud-Kivu. Malheureusement, sa production est demeurée artisanale, malgré son importance commerciale et les pratiques différant d’un endroit à un autre. L’objet de la présente étude est de diagnostiquer l’état sanitaire et les pratiques de fabrication de ce produit. 12 unités de fabrication localisées dans les territoires de Kabare, Kalehe, Uvira et Walungu ont servi de sujet d’études. La méthode des 5 M a permis de classer les divers facteurs susceptibles de contribuer à la dépréciation de la qualité du Mashanza. Les résultats ont montré que la majorité des unités de fabrication sont de type artisanal et ne sont pas conformes sur le plan des installations et de l’assainissement. Les équipements utilisés sont rudimentaires. Le personnel est peu instruit et n’a pas été formé aux bonnes pratiques de fabrication et d’hygiène. Les résultats de l’analyse physico-chimique des produits montrent des valeurs comprises entre 31,1% et 48,8% pour la matière sèche, 3,5 et 3,9 pour le pH, de 0,87 et 0,95 pour l’Aw et de 41,5 et 100,8°D pour l’acidité, traduisant entre autres l’influence de la variabilité des procédés sur la qualité du Mashanza. L’analyse microbiologique révèle une flore aérobie mésophile totale variant entre 4 et 8.102 ufc/ml pour le lactosérum et 0 et 9,8.10² ufc/g pour le Mashanza. Le lactosérum accuse la présence des coliformes : E.coli, S.aureus, les germes anaérobies sulfito-réducteurs, les levures et les moisissures. Leur dénombrement montre des valeurs variant entre 0 et 1,4.10² ufc/g pour les coliformes totaux, 0 et 36 ufc/g pour les coliformes fécaux, 0 et 1,6.10² ufc/g pour E. coli; 0 et 1,2.103, ufc/ml pour les anaérobies sulfito-réducteurs et entre 0 et 1,5.103. ufc/g pour les levures et les moisissures. Salmonella sp. est absent de tous les échantillons de lactosérum et de Mashanza. En général, de « Mashanza » est satisfaisante. Les résultats obtenus permettent d’orienter les producteurs et les chercheurs sur les facteurs pouvant déprécier la qualité du Mashanza et sur lesquels on peut agir. ABSTRACT Mashanza is a traditional fresh cheese produced in eastern DRC, particularly in South Kivu. Unfortunately, its production has remained artisanal, despite its commercial importance and practices differ from one place to another. The purpose of this study is to diagnose the health status and manufacturing practices of this product. 12 manufacturing units located in the Kabare, Kalehe, Uvira and Walungu territories were used as subjects of study. The 5M method classified the various factors that may contribute to the depreciation of the quality of the Mashanza. The results showed that the majority of manufacturing units are of the artisanal type and are not compliant in terms of facilities and sanitation. The equipment used is rudimentary. The staff is poorly educated and has not been trained in good manufacturing and hygiene practices. The results of the physicochemical analysis of the products show values between 31.1% and 48.8% for the dry matter, 3.5 and 3.9 for the pH, of 0.87 and 0.95 for Aw and 41.5 and 100.8 ° D for acidity, reflecting, among other things, the influence of process variability on Mashanza quality. The microbiological analysis reveals a total mesophilic aerobic flora varying between 4 and 8 × 10 2 cfu / ml for whey and 0 and 9.8 × 10 2 cfu / g for Mashanza. The whey accuses the presence of coliforms: E. coli, S.aureus, anaerobic sulphite-reducing germs, yeasts and moulds. Their enumeration shows values ranging between 0 and 1.4 × 10 2 cfu / g for total coliforms, 0 and 36 cfu / g for faecal coliforms, 0 and 1.6 × 10 2 cfu / g for E. coli; 0 and 1.2.103, cfu / ml for the sulphito-reducing anaerobes and between 0 and 1.5.103. ufc / g for yeasts and moulds. Salmonella sp. is absent from all whey and Mashanza samples. In general, Mashanza is satisfactory. The results obtained make it possible to guide producers and researchers on the factors that can degrade the quality of Mashanza and that can be acted on.

The aim of the research. To compare the ovicidal efficiency of insectoacaricides of different composition and manufacturers on flea eggs (Ctenocephalides spp.) for treatemnt of the premises where animals live. Materials and methods of the research. The study was conducted on the basis of the clinic of veterinary medicine "Vetservice" Sumy, laboratory "Veterinary Pharmacy" and "Innovative technologies and safety and quality of livestock products" of Sumy National Agrarian University. The ovicidal effect of insectoacaricides on flea eggs of Ctenocephalides spp. was studied. Ctenocephalides spp. eggs were selected from the pet bedding on which the animal spended most of its time, namely the cats. The studied material was selected with a cosmetic brush. Ctenocephalides spp. eggs were placed into a Petri dish of 10 eggs per each dish. The test material was introduced with a dental probe. There were 4 test dishes, which were treated with insectoacaricides (each test dish was treated with a separate drug) and 1 control dish with no treatment. Microscopy was conducted under a light microscope with magnification X8 of each egg, with following treatment of each egg with insectoacaricides. Monitoring was conducted in 24, 48 and 72 hours after treatment. Results. Research has shown that drugs which demonstrated 100 % ovicidal effectiveness were Sentry Home (pyriproxyfen – 0.02 %, permethrin – 0.2 %, n-Octyl Bicyclohepten – 1.0 %) in 24 hours and Neostomazan (CEVA)(transmix – 5.0 g, tetramethrin – 0.5 g) in 72 hours. Conclusions. Insectoacaricide drug Sentry Home (pyriproxyfen – 0.02 %, permethrin – 0.2 %, n-Octyl Bicyclohepten – 1.0 %), used for the treatment of the premises where the animals live, showed the most pronounced ovicidal effect in 24 hours.

The aim of this study is to evaluate the hygienic quality of the dishes cooked and sold by the women traders in the town of Korhogo. The study was carried out with 45 restaurants in the town of Korhogo. It consisted on the one hand, a survey based on the Ishikawa diagram in order to assess the hygienic conditions, and on the other hand of microbiological analyses of the ready-to-serve meals. A total of 90 samples were taken, including 2 dishes per restaurant, respectively consisting of one hot and one cold dish. Generally, results showed that hygienic conditions were unsatisfactory based on the utilized guidelines. From a microbiological point of view, the meal samples were 75.2% satisfactory, 7.6% acceptable and 17.2% unsatisfactory. In view of these results, it appears essential to improve hygiene conditions by greater involvement of the official services involved in training these traders and monitoring compliance with good hygiene practices and the establishment of a program of cleaning and disinfection of premises and equipment.

Tostones (fried plantains) are consumed by a large segment of the Latin population in Florida. In addition, their use in specialty restaurants is on the increase. However, little is known about the microbial and nutritional quality of this product, particularly as affected by processing. Tostones are prepared by peeling and cutting the plantains into slices; soaking slices in a salt brine; frying, drying and flattening the slices; and refrying them until golden brown. Protein, ash, crude fiber and carbohydrate content increased during preparation as a result of moisture loss during processing. Fat content increased due to uptake during frying. Phosphorus, Na, Hg, Se and Zn content also increased, whereas that of K and Fe decreased. Changes in water activity and pH were not significantly pronounced. Bacillus and Penicillium species were the only organisms isolated from laboratory-prepared samples. The finished product contained 48.0% carbohydrate, 26.5% moisture, 21.5% fat, 2.5% protein, 1.0% ash, 0.5% crude fiber and 395 Kcal/100 g.
