Item Perfil do risco sanitário de alimentos comercializados em feiras especiais de Goiânia - GO(Universidade Federal de Goiás, 2013-04-11) Agostinho, Tânia Maria de souza; Melo, Camila Silveira de; Campos, Maria Raquel Hidalgo; http://lattes.cnpq.br/9910969694141110; Campos, Maria Raquel Hidalgo; Rezende, Cíntia Silva Minafra e; Carvalho, Ana Clara Martins e SilvaThe itinerant sale of food ensures the access to food for the low income urban population. This informal activity, despite its contribution to food access due to the low cost and the convenience of its offer, is an alternative source of food which can pose health risks to the population. Therefore, it is positive due to its socio-economic and cultural importance and satiety of hunger but negative with regard to hygienic and sanitary issues. This study aims to establish the risk profile of ready-to-eat foods sold at street markets in the central region of Brazil. On the preparation of the risk profile, the information gathered must objectively and concisely describe the most relevant knowledge about the problem identified which can propose future actions. The study was a cross-sectional and descriptive with a quantitative approach at 22 street markets registered with the Municipal Economic Development Secretariat of Goiânia, Goiás, Brazil. The data collection occurred in two phases (phase 1 and 2) interspersed by a training course. The data collection procedure involved the application of a checklist based on health legislation at the selected street markets stalls and sample collection of eight food groups for microbiological analysis. Participated in this study 229 points of sale of ready-to-eat food products and/or foods prepared at the place of consumption, in the period from July 2008 to May 2010. Traditional teaching and learning methodology was used to train the food handlers. Considering the results obtained in phases 1 and 2, from both the checklist and the microbiological analysis, it was possible to establish the risk profile of food products sold at these street markets. This profile could contribute to the future intervention actions with the targeted audience. The ready-to-eat foods sold at street markets showed relevant frequency of microbiological non-compliance with the current health legislation. This situation indicates the possibility of the presence of pathogenic bacteria in foods, and therefore, represents a risk to consumers. When establishing the risk profile for the consumption of foods sold by street vendors it is evident the need to develop intervention models with actions directed toward to the improvement of conditions of this activity, known as informal.Item Boas práticas de manipulação de alimentos em cozinhas domiciliares: práticas de trabalhadores domésticos(Universidade Federal de Goiás, 2013-07-07) Oliveira, Allys Vilela de; Campos, Maria Raquel Hidalgo; http://lattes.cnpq.br/9910969694141110; Borges, Liana Jayme; Marques, Rosana de Morais Borges; Campos, Maria Raquel Hidalgo; André, Maria Cláudia Dantas Porfírio Borges; Correia, Márcia Helena SacchiThe Foodborne Diseases stand out as a public health problem, and the residences are among the main sites of occurrence. In many residences the household employee holds the position of food handler, being directly responsible for the health of the food served at the table. The aim of this study was to analyze the practices of food handling and responses to a questionnaire on these practices by domestic workers in their professional environment. Therefore, it was observed hygiene techniques applied for 35 domestic workers during the preparation of a meal, and then were asked about their habits when handling food at work. The instruments used to collect data were a checklist of practice of food safety and a questionnaire about the topic. We calculated descriptive indicators of the sample mean, median and standard deviation. The association between the questionnaire responses and attitudes during observation were calculated by Kappa coefficient and chi-square test (α = .05). The mean observation time of the preparation of the meal in each residence was 46 minutes, while the questionnaire required an average of 15 minutes for each subject answers it. The observation of food handling these individuals showed that 64% of their attitudes were adequate, while in their responses to the questionnaire reported having the habit of performing 70% of procedures. It was found that personal hygiene was the area with lower fitness (40%), while the responses to the questionnaire indicated environmental hygiene as with larger mismatches (56%). The cleaning of hands was prominent among the inadequate procedures during the observation, approximately 85% of the sample committed the fault. Another point that stands out is the use of dish cloth, a practice common in kitchens for 80% of subjects. There was a positive association between education and care practices as observed with the expiration date of food products and defrost foods properly. Already the questionnaire responses were associated with schooling in five items concerning appropriate attire in meal preparation, cleaning and proper storage of food. Statistical analyzes showed that hygiene practices applied in the preparation of the meals were not associated with the answers provided. We conclude that the handling of food for domestic workers exposes diners to contamination by Foodborne Diseases, and that there is a difference between the application of food safety practices in food preparation and answers regarding their practices.Item Perfil higienicossanitário em uma unidade de dietas especiais de um hospital público de Goiânia, Goiás(Universidade Federal de Goiás, 2016-06-10) Pereira, Ana Cristina de Castro; Carvalho, Ana Clara Martins e Silva; http://lattes.cnpq.br/7394320393653597; Campos, Maria Raquel Hidalgo; http://lattes.cnpq.br/9910969694141110; Campos, Maria Raquel Hidalgo; Correia, Márcia Helena Sacchi; Vaz, Inaiana Marques Filizola; André, Maria Cláudia Dantas Porfírio Borges; Brasileiro, Aline AlvesEnteral administration is defined as foods for special purposes, by means of probes or orally. It can be industrialized, or manipulated, and according to the nutritional needs, solely or partially, to replace or supplement for oral feeding for patients. Used in hospitals, clinics or homes, with the aim of maintaining tissues, organs or systems. They are an excellent medium for microbial growth, due to its composition rich in nutrients and exposure time at room temperature for administration. Microbial contamination of enteral formulas can occur in several stages, with a critical moment is the manipulation. Thus, this research assessed the hygienic sanitary quality processing of enteral diets and physical and functional adaptations of the Special Diet unit in a public hospital in Goiânia, Goiás. This is an analytical observational design, carried out in three distinct stages: July and November 2015 and January 2016. A checklist has been applied provided the Board of the Resolution n° 63/2000, for situational diagnosis and health of the place. Microbiological analyzes of water were performed, diet powder and reconstituted according to the standards of the Collegiate Board Resolution n° 12/2001 according to the methodology of the American Public Health Association. It also investigated the presence of Staphylococcus aureus and Escherichia coli in hands and nostrils of the handlers involved in the preparation of diets. For statistical analysis, for the qualitative and discrete variables, we used the Q Test Cochran, while for the quantitative variables we used the Friedmann test. The reconstituted diet was coliforms at 35 °C in 78% of samples, but not confirmed E. coli and coagulase positive Staphylococci counts at any stage. The powder preparation diet and water at all stages, there were no contamination by pathogenic micro-organisms. It detected the presence of S. aureus and E. coli in hands (10% for both micro-organisms) and nasal cavity (10% and 41%, respectively) of the surveyed handlers. Considering the checklist for inspection preparation of diets in the UDE, the average rate of compliance of blocks evaluated was 64.9%, 62.7% and 74.6% in the stages of the study, respectively. The hygienic sanitary profile was partially unsatisfactory. The main problems identified were enteral feedings reconstituted outside the microbiological standards for coliforms at 35 °C, but without the presence of pathogenic micro-organisms. There was inadequate microbiological profile of hands and nostrils of some manipulators and low compliance rates in some blocks, indicating a need for readjusting the physical structure, better quality control record of the manipulated diets and reassessment of the handlers hygiene practices, since this can be seen as one of the important factors in the transmission of diseases, and responsible for foodborne outbreaks.Item Condições higienicossanitárias de lactários hospitalares de Goiânia(Universidade Federal de Goiás, 2014-08-28) Rodrigues, Camilla Alves Pereira; Borges, Liana Jayme; http://lattes.cnpq.br/7394320393653597; Diaz, Mario Ernesto Piscoya; http://lattes.cnpq.br/8921949936090276; Campos, Maria Raquel Hidalgo; http://lattes.cnpq.br/9910969694141110; Correia, Marcia Helena Sacchi; Carvalho, Ana Clara Martins e Silva; Campos, Maria Raquel HidalgoThis work aimed to evaluate the profile of microbiological contamination in infant formula milk powder and reconstituted, water and utensils used in food preparation for infants less than one year in lactaries five hospitals with pediatric care in the city of Goiânia, Goiás state, Brazil. Also conducted a follow-up of professionals involved in the preparation and distribution of infant formula, through verification of good handling practices on lactaries room, as well as evaluation of the hygienic conditions of the hands and nasal pits. 640 samples were obtained considering the two stages of the study, so before and after training in best practices for handlers involved. These samples for microbiological determinations coliforms at 35 °C and 45 °C, coagulase positive staphylococci, Bacillus cereus, Salmonella, Pseudomonas aeruginosa and mesophilic aerobic microorganisms, Escherichia coli and Staphylococcus aureus were performed. Presence of P. aeruginosa was observed in a sample of water and another of aerobic mesophilic. All samples of infant formula milk powder proved adequate to consume according to current legal resolution, but a sample of them, reconstituted, presented coliform count at 35 °C above the limit allowed by law. There was an improvement in the microbiological profile of respondents between the two stages of the research vessels, being statistically significant at 35 °C for coliforms and P. aeruginosa. Escherichia coli and Staphylococcus aureus in nasal cavity and hands of food handlers were found. None of lactaries surveyed during the study demonstrated satisfactory level of compliance against the current health legislation after application of the checklist in good handling practices. Even after training several nonconformities relating the adjustments set was identified. With this study it was concluded that the infant formula infants were offered to secure the microbiological point of view. Good manufacturing practices and training tools can be permanent improvement in sanitary hygienic control in the food production process. We need better public policies to develop, oversee and implement effective legislation to health services, as well as ensure the sanitary quality of food to the population.Item Perfil microbiológico de queijo minas frescal industrializado e artesanal comercializado em Goiânia, Goiás(Universidade Federal de Goiás, 2015-06-30) Silva, Lívia Milhomem; Borges, Liana Jayme; http://lattes.cnpq.br/7394320393653597; Campos, Maria Raquel Hidalgo; http://lattes.cnpq.br/7997149004572420; Campos, Maria Raquel Hidalgo; Carvalho, Ana Clara Martins e Silva; Correia, Marcia Helena SacchiThe fresh Minas cheese is widely consumed in Brazil due to its good taste, people's behavior and its easy marketing. It’s a highly sensitive food to microbial contamination due to its characteristics and may have pathogenic microorganisms, a result of a possible failure in the hygienic and sanitary control. The Escherichia coli is a bacterium commonly found in this product and stands out for being indicative of fecal contamination and it’s related to resistance to antimicrobials and high genetic variability between strains found in food. This study evaluated the microbiological quality of fresh Minas cheeses, handmade and industrially produced according to Brazilian legislation. In addition, the aim of this study was also test the susceptibility of E. coli to different antibiotics and identifies its genetic profile. The samples were collected in supermarkets and fairs in the city of Goiânia, Goiás and subjected to microbiological analysis in accordance with the standards established by Resolution RDC nº. 12 of January 2, 2001, of the National Health Surveillance Agency, following the methodology recommended by the American Public Health Association. The antimicrobial susceptibility testing followed the disk diffusion technique in Mueller- Hinton agar and, the genetic variability, was observed by the technique of Pulsed Field Gel Electrophoresis. The analysis detected the presence of coliforms in 100.0% of samples, while fecal coliforms were observed in 10.0% and 14.3% of samples from supermarkets and fairs, respectively. 12.5% of the samples fairs confirmed the presence of Escherichia coli. Handmade cheeses were more contaminated than industrially produced chesses. Of eight isolates, one (8.0%) were sensitive to ampicillin, six (48.0%) showed intermediate susceptibility to cefepime and one (8.0%) was resistant to tetracycline, while 100.0% were sensitive to amoxicillin/clavulanic acid, aztreonam, ceftazidime, ceftriaxone, ciprofloxacin, gentamicin, imipenem, sulfamethoxazole/trimethoprim and piperacillin-azobactam. The cheeses showed high contamination than the limits established to Brazilian legislation, making it unfit for human consumption. These results indicate failures in hygienic sanitary controls in the food chain. The technique of PFGE revealed high genetic variability among isolates while the antibiogram revealed high sensitivity of isolates to antibiotics.Item Processamento e condições higienicossanitárias de frutos e polpas em comunidades quilombolas(Universidade Federal de Goiás, 2016-05-02) Silva, Natália Menezes; Santiago, Raquel de Andrade Cardoso; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4703571H3; Campos, Maria Raquel Hidalgo; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4700986T7; Caliari, Márcio; André, Maria Cláudia Dantas Porfírio BorgesThe pulp processing is a possibility for use of fruits by traditional people like the quilombolas, inserted in a context in which native fruits are little consumed. Therefore, the hygienic and sanitary quality is essential in the production of safe food. This study aimed to evaluate the processing and hygienic and sanitary conditions of fruits and fruit pulps in quilombola community. The survey was conducted in the Community of the Remnant of Quilombo do Pombal, Goiás, Brazil. To evaluate the physical and functional conditions was applied a checklist before and after the implementation of structural adjustments, training and implementation of the Manual of Good Practices and Standard Operating Procedures. Data were categorized according to the percentage of adequacy. Microbiological analyzes of 32 samples were taken including, fruits of Cerrado found in the community and fruits and their pulps in different steps of the flowchart production. The hazards and critical control points were listed in the production flow chart. The physical and functional diagnostic performed indicated average compliance of blocks of 30.18%, being classified in Group 3, unsatisfactory. After interventions, there was 62.13% of compliance, with classification in Group 2, regular (p <0.05). The intervention effect was significant (p <0.05) for five of the seven blocks evaluated. Microbiological analysis indicated that all the native fruits collected are in accordance with the recommendations of the current health legislation. Fruits and pulps included into processing flowchart presented in accordance with sanitary standards for fecal coliform count and detection of Salmonella spp, however, the mold count and yeast in eight pulps analyzed indicated that five of them had counts above the established by legislation. The results suggest fruit contamination since the harvest and multiplication of such micro-organisms in the remaining stages. The washing and filling steps were able to reduce the load of molds and yeasts. It is understood that the physical and functional adaptations implemented were important to increase the percentage of adequacy of the items, however, the persistence of shortcomings in the work process may compromise the quality of the final product, stressing the need for compliance with good practices.Item Qualidade microbiológica de água tratada para hemodiálise e caracterização de bactérias patogênicas(Universidade Federal de Goiás, 2015-02-03) Souza, Bárbarah Gregório de Araújo; Borges, Liana Jayme; http://lattes.cnpq.br/7394320393653597; Freitas, Ana Tereza Vaz de Souza; http://lattes.cnpq.br/5288011784889591; Campos, Maria Raquel Hidalgo; http://lattes.cnpq.br/9910969694141110; Pereira, Edna Regina Silva; André, Maria Cláudia Dantas Porfírio Borges; Campos, Maria Raquel HidalgoHemodialysis is a primary treatment for chronic renal patients in the terminal phase. In this therapy, the water is used for the dialysis solution production and dialyzers reuse, and therefore the microbiological quality should be guaranteed, once excessive levels of bacteria are responsible for symptoms such as fever, chills, hypotension and shock, and may even lead to death of patients. Thus, this study aimed to evaluate the water microbiological quality used in hemodialysis centers and characterize isolated pathogenic bacteria from this water. During the months of May and June 2014, were collected in two stages, water samples from four collection points in 12 hemodialysis centers of the cities of Goiania-GO and Aparecida de Goiânia-GO. The protocol followed the microbiological parameters of Board Resolution No. 11/2014, in addition to fecal coliforms, Escherichia coli and Pseudomonas aeruginosa research, according to the American Public Health Association. The strains of pathogenic bacteria were characterized phenotypic and genotypically through the antibiogram and Pulsed Field Gel Electrophoresis. Of the 96 water samples, 7.3% were classified contaminated with total coliforms, 1.1% by fecal coliforms, 18.7% by heterotrophic bacteria and 10.4% by P. aeruginosa, the latter being present in 6 hemodialysis centers. E. coli strains were not isolated in the water samples studied. All P. aeruginosa strains were resistant to cefepime and only one strain was also resistant to aztreonam and piperacillin-tazobactam. Genotypic analysis revealed eight different electrophoretic profiles and showed the persistence of the same bacteria clones in the two phases of collection in a hemodialysis center. It can be concluded that the water used in dialysis units has unsatisfactory hygienic and sanitary conditions and pathogenic bacteria strains have antibiotic resistance pattern used in your control and high genetic diversity, revealing the potential health risk to patients undergoing hemodialysis.Item Caracterização de riscos microbiologicos na administração de dietas enterais em um hospital público de Goiânia, Goiás(Universidade Federal de Goiás, 2015-03-31) Taboada, Maria Izabel de Souza; Borges, Liana Jayme; http://lattes.cnpq.br/7394320393653597; Campos, Maria Raquel Hidalgo; http://lattes.cnpq.br/9910969694141110; Tipple, Anaclara Ferreira Veiga; Carvalho, Ana Clara Martins e Silva; Campos, Maria Raquel HidalgoEnteral nutrition therapy englobes all the procedures for maintenance and recovery of patients who are unable to be fed orally by the offer of enteral feeding. Is associated with many types of complications by pathogenic microorganisms that may lead to development of nosocomial infections. The aim of this study was characterize microbiologic risks in the administration of enteral feeding formulas at a teaching-hospital in Brazil. Is a cross-sectional study, where were obtained 280 samples at total: 140 of enteral feeding formulas before and after the administration and 140 of filtered water before and after rinsing the delivery sets. In the enteral feeding formulas coliforms at 35ºC and Escherichia coli was enumerated. The water analysis included enumeration of heterotrophic bacteria and detection of Pseudomonas aeruginosa, coliforms at 35ºC and Escherichia coli. For the results interpretation Brazilian legislation for enteral feeding and water was used. To check the compliance of administration procedures according to legislation, a check list was fill in the moment of delivery set change. The enumeration of coliforms at 35ºC was over the limits of legislation in 75% of the enteral feeding samples after administration. No presence of E. coli was detected neither in enteral feeding or water samples. In the water samples analyzed, presence of coliforms at 35ºC was founded in 98% and Pseudomonas aeruginosa in 88% after rinse the delivery sets. By the checklist was possible to observe that the legislation recommendations were not fulfilled in the totality. Through this study was possible to have a perspective of the major attention that has to be given to administration procedures and the prevention measures to minimize risks of pathogenic microorganisms so that way reduce the incidence of nosocomial infections.
