Resumo O estudo foi realizado com o objetivo de verificar tanto a condição microbiológica quanto as diferenças físico-químicas existentes em pólens armazenados por diferentes espécies de abelhas sem ferrão no Nordeste do Brasil. Os pólens armazenados foram coletados nas colônias mantidas em meliponários das seguintes espécies: Melipona subnitida, M.scutellaris, M. mandacaia, Scaptotrigona sp. e Frieseomellita varia. Com relação às análises de qualidade microbiológica, as mesmas foram realizadas em micro-organismos indicadores de qualidade comercial (mesófilos, bolores e leveduras), qualidade sanitária (Staphylococcus coagulase positiva, coliformes fecais e Escherichia coli), e de segurança (esporos de Clostridium sulfito redutores e Salmonella spp.). Para os parâmetros físico-químicos, os mesmos foram avaliados de acordo com a exigência do Regulamento Técnico (RT) de qualidade para pólen apícola, e também para compostos fenólicos. Todas as amostras apresentaram condição microbiológica de acordo com as recomendações aceitáveis para o consumo humano. Os resultados confirmaram as diferenças na composição físico-química do pólen armazenado das cinco espécies; no entanto, houve formação de três grupos de pólens armazenados com base nos parâmetros físico-químicos. As amostras da espécie M. scutellaris apresentaram conteúdo de compostos fenólicos cinco vezes mais elevado aos outros méis das espécies avaliadas. Logo, este estudo permitiu conhecer a composição dos pólens armazenados por abelhas sem ferrão, por conseguinte reforçando a necessidade de reformular o Regulamento Técnico (RT) existente no Brasil para pólen apícola, de forma a abranger os pólens armazenados das espécies nativas.

Hazard analysis critical control point (HACCP) module was prepared for one of the most popular fast food momo (chicken momo and buff momo). For this, hazard analysis was conducted in eight different restaurants of Katmandu city by observing all the steps of preparation, monitoring time-temperature throughout the preparation process and collecting samples of different stages of these food. The samples were assessed for total aerobic mesophilic count (TAMC), total coliform count, total Staphylococcus aureus count, total yeast and mold count, detection of Salmonella spp. and Escherichia coli. During preparation of chicken momo, the highest TAMC, yeast and mold count, coliform and S. aureus count were found to be 2.8 × 106cfu/g, 2.1 × 103cfu/g, 1.92 × 105cfu/g and 3.4 × 103cfu/g respectively. While preparation of buff momo, the highest TAMC, yeast and mold count, coliform count and S. aureus count were found to be 2.82 × 106cfu/g, 1.9 × 103cfu/g, 2.1 × 105cfu/g and 2.8 × 103cfu/g respectively. These values and near to these values too were obtained from the samples of pickles, spices, raw momo, mixture of minced meat with spices and raw meat. The organisms originally present in the raw materials were subsequently transmitted to all the preparatory stages but was not observed after steaming and hence the final steamed product of both kinds of momo were free from microorganisms. Thus from the above findings, it was concluded that steaming was the main critical control point (CCP), which if done for proper time and temperature, can eliminate all the contaminating organisms.

With a previous observation of Escherichia coli growth cessation along with temperature variation within three different bacteriological culture media (nutrient agar, Luria-Bertani agar and minimal agar), current investigation further depicted on the possible growth dynamics of Escherichia coli (SUBE01) and Salmonella (SUBS01) growth and viability upon supplementation of different carbon sources (dextrose, sucrose, lactose, glycerol and tween 20) at 37°C under the aeration of 100 rpm. Viability of the tested bacterial species was assessed through the enumeration of the colony forming unit (cfu) appeared upon prescribed incubation for 12-24 hours on different agar plates consisting of the above mentioned carbon sources. Besides, to inspect the cellular phenotypic changes, morphological observations were conducted under the light microscope. Variations in bacterial growth (either growth acceleration or cessation) were further noticed through the spot tests on the agar plates. Considerable shortfalls in the culturable cells of E. coli and Salmonella spp. were noted in the minimal media separately consisting of sucrose, lactose, glycerol or tween 20 while an opposite impact of accelerated growth was noticed in the media supplied with dextrose. The data revealed a hierarchy of consequence of carbon sources as nutrient generators whereby the favourable bacterial growth and survival order of the carbon sources was estimated as dextrose > glycerol > lactose > tween 20 > sucrose.Bangladesh J Microbiol, Volume 32, Number 1-2,June-Dec 2015, pp 39-44
