Eighty-eight samples of ground meat were randomly collected from retail stores in the metropolitan area of Monterrey, Mexico, and were analyzed for microbial contamination. Methods were those recommended by the Mexican regulation and/or the U.S. Food and Drug Administration. Over 75% of the samples contained 105 total mesophilic microorganisms per g, and over 40% had 106 total coliforms per g. Fecal coliforms were present in most samples. Staphylococcus aureus was detected in 2.3% of the samples, Salmonella spp. in 11.4%, Listeria spp. in 62%, and L. monocytogenes in 16%. Escherichia coli was detected in 76% of samples, but none was serotype O157:H7. Shigella spp. was not found in any sample. Fusarium spp. and Mucor spp. were detected in 3.4% of the samples, and low levels of yeast in 93%. The microbiological quality of the ground meat analyzed was unsatisfactory, and the product could be an important cause of food poisoning.

Egusi pudding is one of the most popular traditional dishes of the Cameroonian population. Besides its nutritional values, it is also endowed with a sociocultural character. Nowadays, consumer demand for Egusi pudding has increased and the dish is sold as street food in several cities of Cameroon and mostly under uncontrolled hygienic conditions. The objective of this study was to assess the microbiological quality of Egusi pudding sold in the city of Yaoundé taking into consideration the protein sources and the sampling sites. Five types of Egusi pudding samples based on protein sources were randomly collected from 25 sellers distributed in 7 districts in the city of Yaoundé and their microbiological quality were assessed. The results showed that the total aerobic count of the different samples (2.97 ± 0.03 to 4.43 ± 0.05 Log CFU/g) was under the threshold value (5.47 Log CFU/g) recommended for food intended for human consumption. Loads of fecal coliforms (1.47 ± 0.00 to 5.47 ± 0.00 Log CFU/g) in 40% of samples, Escherichia coli (2.39 ± 0.12 to 5.43 ± 0.05 Log CFU/g) in 60% of samples, fecal streptococci (2.90 ± 0.15 to 4.74 ± 0.05 Log CFU/g) in 88% of samples, Pseudomonas spp. (3.39 ± 0.15 to 5.43 ± 0.06 Log CFU/g) in 100% of samples, and the presence of Salmonella spp. in 56% of samples revealed a poor level of hygiene of the vendors. Pathogens associated with unsafe food handling such as Staphylococcus spp. were found in 100% of samples at loads (3.84 ± 0.18 to 5.43 ± 0.05 Log cfu/g) higher than the norms of the European Commission. Potential toxigenic pathogens such as Clostridium perfringens, Yersinia enterocolitica, Bacillus cereus, and moulds were also found, respectively, in 100, 96, 96, and 100% of samples. Overall, the most contaminated samples were those made with sardine as protein source, 92.85% (n = 23/25), followed with beef (88.57%), mackerel (84.28%), cod (82.85%), and control (77.1%). The results of this study suggest that important measures should be taken by the Public Health Service in order to sensitize the producers and vendors of Egusi pudding on the respect of good hygiene, manufacturing practices, and the continuous monitor of the quality of traditional products sold in markets.

Due to the increase in the consumption of natural products, there has been a growing use and commercialization of bee pollen, thus, the need for a greater quality control regarding the physical-chemical and microbiological characteristics of this product is justified. In this way, the research aimed to determine the physical-chemical, microbiological and sensorial characteristics of four brands of dehydrated pollen, marketed in natural products houses in different parts of the city of Belém-Pará. Microbiological (aerobic mesophilic bacteria, fungi and yeasts, Coliformes at 45°, Salmonella sp and Staphylococcus aureus) and sensorial analyzes were carried out in the physicochemical analyzes (moisture, ashes, lipids, proteins, pH, free acidity, total sugars). The results obtained were within the parameters of quality allowed by the Brazilian legislation for dehydrated pollen. Regarding the microbiological analysis, all brands showed absence of Staphylococus aureus and Salmonella spp. For the sensorial analysis, the C mark presented better results for both flavor and aroma, confirming the quality of the dehydrated pollen commercialized in Belém-Pa.

A cosmetologia é a ciência que engloba e estuda os cosméticos, desde conceitos iniciais até a sua fabricação, tornando-se uma ciência multidisciplinar. Para garantia de um uso seguro e eficaz dos cosméticos é necessário a realização de análises para se conseguir um padrão de qualidade. Quando há indícios de contaminação por microrganismos no cosmético, diversos problemas podem ser encontrados, como a ocorrência de patologias específicas, causando altos riscos e complicações à saúde do usuário. O objetivo deste trabalho foi investigar qualitativamente através de análises microbiológicas a qualidade dos produtos cosméticos de maquiagem usados de forma compartilhada, utilizando amostras colhidas aleatoriamente em uma loja de varejo, que foi selecionada por ser de grande circulação, da cidade de Juazeiro do Norte, Ceará. Nesta pesquisa foram analisadas oito amostras coletadas durante o período de outubro e novembro de 2017. As análises que foram realizadas seguiram a Farmacopeia brasileira. Como resultado obteve-se um percentual de 87,5 % de contaminação microbiana, evidenciando a presença de Staphylococcus aureus, Escherichia coli, Enterococcus sp. e Pseudomonas aeruginosa, sendo que apenas uma das oito amostras analisadas mostrou-se adequada para uso seguindo os limites de aceitação microbiológicas permitidos por lei. Baseados nesses resultados foi possível concluir que o índice de contaminação das amostras de batons que são utilizadas de modo compartilhado são potencialmente maiores. Com isso, intensifica-se a necessidade de medidas que impeçam o compartilhamento dos produtos cosméticos, com a finalidade de diminuir o risco de uma infecção coletiva.   Palavras-chave: Cosméticos. Uso compartilhado. Contaminação.   Abstract Cosmetology is the science that encompasses and studies cosmetics, from initial concepts to their manufacture, becoming a multidisciplinary science. To guarantee a safe and effective use of cosmetics it is necessary to carry out analyzes to achieve a quality standard. When there is evidence of contamination by microorganisms in the cosmetic, several problems can be found, such as the occurrence of specific pathologies, causing high risks and complications to the health of the user. The objective of this scientific work was to qualitatively investigate through microbiological analysis the quality of cosmetic makeup products used in a shared way, using samples collected randomly in a retail store, which was selected because it is of great circulation, in the city of Juazeiro do Norte, Ceará. In this research, eight (8) samples collected during the period of October and November 2017 were analyzed. The analyzes that were carried out followed the Brazilian Pharmacopoeia. As a result, a percentage of 87.5 % of microbial contamination was obtained, showing the presence of Staphylococcus aureus, Escherichia coli, Enterococcus sp. and Pseudomonas aeruginosa, with only one of the eight samples analyzed being suitable for use following the limits of microbiological acceptance allowed by law. Based on these results it was possible to conclude that the contamination index of the lipstick samples that are used in a shared way are potentially higher. As a result, the need for measures to prevent the sharing of cosmetic products is intensified, in order to reduce the risk of a collective infection.   Keywords: Cosmetics. Shared Use.

O queijo Minas frescal é um dos mais populares do Brasil, porém o alto teor de umidade associado ao métodode processamento, muitas vezes artesanal, e de armazenamento desse produto o tornam muito perecível.Este trabalho teve como objetivo avaliar e comparar a qualidade microbiológica de queijo Minas frescalcomercializado na cidade de Curitiba (PR) nos anos de 1999 e 2009, verificando a evolução na qualidadehigiênico-sanitária desse produto no período de 10 anos. Foram analisadas 11 marcas comerciais de queijo Minas frescal disponíveis no comércio varejista da cidade de Curitiba, sendo amostradas cinco unidades de cada marca, totalizando 55 amostras. Os queijos foram submetidos à pesquisa de Salmonella spp., contagem de coliformes totais e Escherichia coli, contagem de Staphylococcus coagulase positiva e contagem de aeróbios mesófilos, com resultados expressos em UFC/g. Das 55 amostras de queijo, 41,82% e 78,18% apresentaram contagem de E. coli e de coliformes totais acima do limite permitido, respectivamente. Somente uma amostra (1,82%) do total avaliado mostrou-se em desacordo com os padrões para S. coagulase positiva e uma para Salmonella spp. Ambas as amostras foram adquiridas em 2009. Todas as amostras avaliadas em 2009 apresentaram elevada contagem de aeróbios mesófilos, revelando alta carga microbiana. Comparativamente, os queijos avaliados em 1999 mostraram qualidade microbiológica superior aos queijos avaliados em 2009 (p < 0,05). Destes, 100% apresentaram no mínimo um parâmetro microbiológico em desacordo com a legislação vigente, indicando que a qualidade dos queijos Minas frescal avaliados em 2009 apresentou-se inferior a dos queijos avaliados em 1999.

One hundred twenty-seven 60-d aged Cheddar cheese samples produced by 21 provincially inspected cheese plants were analyzed by 8 regional laboratories of the Ontario Ministry of Health. Coliforms were detected in 37 (31.2%) and fecal coliforms confirmed in 22 (18.3%) samples, with geometric mean counts per g of 92.5 and 79.3, respectively. Staphylococcus aureus was found in only two products at a level of &gt;1000 per g. Salmonella spp. and Campylobacter jejuni were not isolated from any of the samples tested. Yersinia enterocolitica was isolated from one product; however, the isolate was bile esculin-and salicin-positive, and considered a non-pathogenic biotype. The pH of these aged Cheddars ranged between 4.98 and 5.50, with a mean of 5.26. Alkaline phosphatase activity was detected in 94 (79.7%) of the 118 samples tested. These results suggest that 60-d aged raw milk Cheddar cheese produced in Ontario does not pose a significant bacteriological health risk.

A study on the presence of Salmonella spp. in live molluscs was performed, which included a description of the different serovars isolated and their relationship to the marine environment. A total of 2,980 samples of shellfish from Galicia (N.W. Spain) were tested for the presence of Salmonella spp. between September 1998 and August 2001. The overall incidence of Salmonella was 1.8% and showed a slight rise during the 3 years of the study. Mussels and oysters presented a higher incidence than clams and cockles, possibly because of their distinct growing habitat. A seasonal pattern was noted for the isolation of Salmonella spp.: 54% of the isolations were detected from September to November. That nearly 67% of the total Salmonella was isolated from shellfish with fecal coliform levels &lt;300/100 g (the maximum level criteria in the European Communities regulations) supported the view that low levels of fecal coliforms do not necessarily indicate the absence of Salmonella. A total of nine serovars were found in the 54 Salmonella isolated. Salmonella Senftenberg was the most frequent (50%), followed by Salmonella Typhimurium (18%) and Salmonella Agona (17%). Salmonella Senftenberg was detected frequently during the year, whereas the remaining serovars were detected only on occasional contamination events.

Water is the basic drink for human beings and drinking water in sachets is very popular because of its relatively low cost and availability. The aim of this study is to determine the bacteriological profile of sachet drinking water sold in the city of Yaounde. It was a descriptive cross-sectional study covering the period from March to June 2019, carried out in the application laboratory of ETMS-Yaounde. A total of 230 samples of drinking water in sachets purchased in different markets in the city of Yaounde were analyzed using Mac Conkey's flooding method. The identification was done on the API 20 E Gallery and the susceptibility test on Mueller Hinton media. The size of the sample was 230 packaged sachet drinking water and 213 of the 230 revealed 92% of positive culture of germs, and only 17 samples gave a negative culture, at a percentage of 8% of isolated germs. The isolated bacterial species and their respective abundances in samples were Enterobacter gergoviae (3%), Klebsiella pneumoniae (5%), Proteus mirabilis (5%), Serratia fonticola (5%), Salmonella choler arizonae cloacae (8%), Salmonella spp. (8%), Enterobacter cloacae (10%), Staphylococcus aureus (10%), Pseudomonas aeruginosa (18%) and Staphylococcus epidermidis (28%). All these tested germs were resistant to Amoxicillin and Erythromycin and 70% of tested germs were sensitive to Gentamycin. Overall, the results revealed poor microbiological quality of these waters. This exposes consumers to health risks, and it is important to inform and sensitize consumers about the risks involved, to educate producers and to control their activities by the health services.

The aim of this work was to assess the microbiological quality of spices sold in Botucatu, São Paulo, Brazil. A total of 233 samples were analyzed for mesophilic bacteria, thermotolerant coliforms, Bacillus cereus, Staphylococcus aureus, and Salmonella. Data showed that 21 and 5.6% of these samples were not in agreement with the standards of Brazilian law, due to an excess of coliforms and to the presence of Salmonella, respectively. Black pepper and cumin exhibited the lowest microbiological quality, whereas bay leaf showed the highest quality. It was concluded that the seasonings possessed poor microbiological quality, and new alternatives should be taken in the primary production in order to improve this quality. Irradiation may also be a tool to assure the safety of these products.
