Avaliação das condições higiênico-sanitárias da produção de refeições à base de carne da alimentação escolar no município de Natal-RN

The National School Nutrition Program is the oldest program in the country directed at food and nutrition safety. Its aims are to offer nutritional food as a supplement to students of public and philanthropic schools. Studying school nutrition transcends the investigation as a purely social program, given that it reaches the fields of public health, nutrition and food, using a wide variety of approaches. Thus, it is characterized by a multidisciplinary study, where the disciplines work side by side in distinct aspects of a single problem. Aim: This study aims to assess hygiene practices during the preparation of meat-based meals in public schools in the city of Natal, Brazil. Methods: A list was applied at 27 schools to identify the procedures of good food preparation practices. In addition, cooking and meal distribution temperature were measured and a microbiological analysis of the final preparation and of the water used in preparing it was performed. For microbiological analyses of the food, we analyzed coliforms at 45°C, coliforms at 35°C and Enterococcus, and for the water, we analyzed thermotolerant coliforms and total coliforms, using the methods recommended by APHA, 1995. Results: Most of the schools did not meet the required standards in all the variables related to good food preparation practices, except for the time spent preparing the meat, in which 89% were within the norm. Cooking temperature of the meals was within the standard; however, the temperature at distribution and the time spent dispensing the meals were inadequate. Of the 27 schools, 22 (81.5%) showed the presence of coliforms at 35° C in at least one meal sample and 18 (66.7%) had values above the recommended limit for coliforms at 45°C. The presence of E. coli was identified in 6.1% of the samples analyzed. The presence of Enterococcus was not found at any of the schools. With respect to the water, the North district of the city was the only one that did not meet the standards for the two indicators evaluated. The contamination found was not associated with the hygiene or food storage problems observed. Conclusions: The results show that the hygiene-sanitary conditions of meat-based public school meals were unsatisfactory, demonstrating the need for improvements in the production process to preserve the health of the student population. Multidisciplinarity: Researchers from the areas of food microbiology, nutrition, public health and statistics took part in this study, a decisive factor for characterizing the research as multidisciplinary

Inclusão de farinha de resíduos da indústria de filetagem de tilápias na alimentação de girinos de rã-touro (Rana Catesbeiana Shaw,1802)

The objective of this experiment was to evaluate the inclusion of meal of tilapia industrial waster in bullfrog tadpoles' diets (Rana Catesbeina Shaw, 1802). Two hundred fifty tadpoles with initial weight and length of 0,18 +/- 0,05g and 2,50 +/- 0,18 centimeters were used, respectively, they were used and distributed in 25 aquariums of 30 liter each in a complete randomized design with five treatments and five repetitions. The tadpoles were fed four times a day with diets containing 0, 5, 10 and 15% of inclusion of tilapia filleting and another diet with 0% of supplemented tilapia filleting with synthetic methionine, being supplied four times a day at ease. The experiment period was 30 days. The diets with tilapia filleting inclusion and methionine supplementation did not have influence in the final weight and length averages, feed survival and conversion of bullfrog tadpoles. It cam be used until 15% of tilapia filleting inclusion in the bullfrog tadpoles food. The synthetic methionine supplementation in diets for bullfrog tadpoles is not necessary in diets with levels over 0,471/4 of the total methionine.

Uso de bandejas de alimentação na fase de engorda do camarão-da-Amazônia Macrobrachium amazonicum (HELLER, 1862)

The aim of this experiment was to evaluate the hypothesis that the M. amazonicum prawns accept feeding in trays. Six ponds were stocked with 10 juveniles II (1.2 +/- 0.7 g) per m(2) in 02/14/2003. An entirely randomized experimental design with 2 treatments (feeding in trays or feeding to the throw) and 3 replicates was used. Prawn average weight, survival, productivity, and physical and chemical variables of the water were compared between treatments using "t" test of Student. Average weight, survival and productivity were, respectively, 7.2 +/- 0.3 g, 46.8 +/- 7.8% and 335 +/- 45 kg/ha in feeding tray treatment and 6.8 +/- 0.1 g, 85.8 +/- 5.2% and 586 +/- 42 kg/ha in feed to the throw treatment. Survival and productivity differed significantly (p<0.5), while that average weight didn't differ significantly. M. amazonicum needs to use further number of trays per area, possibly due to territorial and aggressive behavior.

Proteína e energia na alimentação de pacus criados em tanques-rede

O objetivo neste trabalho foi avaliar o desempenho de pacus (Piaractus mesopotamicus) criados em tanques-rede e alimentados com dietas contendo níveis de proteína bruta (PB) e energia digestível (ED). Foram utilizados 3.960 peixes com 293,38 ± 5,67 g de peso inicial, distribuídos em 18 tanques-rede de 5 m³, com 220 peixes por unidade experimental (44 peixes/m³), em esquema fatorial 3 × 2, composto de três níveis de proteína bruta (25, 30 e 35%) e dois de energia digestível (3.250 e 3.500 kcal/kg). O arraçoamento foi realizado quatro vezes ao dia (às 9 h, 11h30min, 14 h e 17 h) até a saciedade aparente dos animais. Não foram observadas diferenças no ganho de peso, na taxa de sobrevivência, na conversão alimentar aparente nem na taxa de crescimento específico. No entanto, houve diferença na deposição de gordura visceral, que foi maior nos animais alimentados com as rações de maior nível energético. Também não foi observada influência dos níveis de proteína e energia da dieta nos teores de umidade, proteína bruta, matéria mineral e lipídio dos filés. Rações contendo 25% de proteína bruta e 3.250 kcal/kg de energia digestível promovem melhores resultados de desempenho.

Qualidade nutricional dos cardápios em escolas públicas e alcance às metas do programa nacional de alimentação escolar em município do nordeste brasileiro

O Programa Nacional de Alimentação Escolar tem como objetivo atender as necessidades nutricionais dos alunos durante sua permanência em sala de aula, contribuindo para o crescimento, o desenvolvimento, o rendimento escolar e a formação de hábitos alimentares saudáveis. Diante da relevância social e considerando os princípios do direito humano da alimentação adequada e da segurança alimentar, é fundamental o monitoramento da execução e consecução das metas nutricionais estabelecidas pelo programa. Desta forma, este estudo teve como objetivos analisar a qualidade nutricional dos cardápios ofertados em escolas públicas de um município rural do Nordeste brasileiro, quanto à composição nutricional, custo com gêneros alimentícios, nível de adesão dos escolares às refeições oferecidas e atendimento às recomendações nutricionais do Programa Nacional de Alimentação Escolar. Foi desenvolvido estudo transversal, realizado com 473 escolares, em Nísia Floresta, município do Estado do Rio Grande do Norte. A frequência de consumo semanal da alimentação escolar foi analisado segundo o padrão adotado por Sturion et al., que classifica o nível de adesão em: efetiva (quatro a cinco dias), média (dois a três dias) e baixa (um dia). Analisou-se 64 preparações da alimentação escolar, eleitas de forma aleatória por conglomerado, avaliadas quanto à energia, macronutrientes e micronutrientes (vitaminas A e C, ferro, zinco, magnésio e cálcio). Utilizaram-se como parâmetros as recomendações nutricionais estabelecidas pelo programa (2009), para atender 20% das necessidades nutricionais diárias, considerando as faixas etárias de 6 a 10, 11 a 15 e 16 a 18 anos. Calculou-se o custo das preparações servidas com base na licitação realizada no município. A associação entre adesão e extratos etários foi investigada utilizando a análise de correlação. A energia oferecida pelos cardápios foi inferior a recomendação em até 50%. As refeições atingiram, em média, 249,34 kcal (±64,43). Observaram-se preparações com inadequação dos macronutrientes e micronutrientes, exceto para proteínas (102,3%) e lipídios (100,1%), na faixa etária ix de 6 a 10 anos. O custo das preparações foi R$ 0,53 (±0,16), sendo provenientes 56,6% de recursos federais e 43,4% da contrapartida municipal, com essencialidade de recursos municipais no provimento do custo. Quanto à adesão, 93,9% dos escolares informaram consumir os lanches. Para o nível de adesão, obtiveram-se: 67,2% efetiva, 21,8% média e 4,9% baixa. Foi encontrada associação significativa entre as variáveis adesão e idade (χ2 = 89,36; GL=6; P < 0,001), sendo a baixa adesão encontrada, sobretudo, na faixa de 16 aos 18 anos. Os cardápios ofertados não atingem as metas do Programa Nacional de Alimentação Escolar, favorecendo a insegurança alimentar, especialmente aos adolescentes. Portanto, há necessidade de reformulações, planejamento, e implantação de refeições diferenciadas e adequadas às distintas faixas e factíveis de execução

Como material de estudo utilizou-se escritos memorialísticos que, avaliados na perspectiva da antropologia da doença e do doente, permitem estabelecer a rede de significados elaborados pela comunidade dos enfermos.

Eleições, pesquisas e estratégias de marketing: a campanha eleitoral de Micarla de Sousa em Natal (2008)

From the importance that the political science and the social sciences began to give the electoral programs on TV, were examined in that work academic the effects of research in electoral marketing strategies in Gratuitous Timetable of the Electoral Publicity of the marketing year the candidate Micarla de Sousa (PV) in 2008 for the prefecture of Natal. To analyze the marketing strategies of electoral candidate Micarla de Sousa were used three sources of data: the HGPE on the first part, The interview with the coordinator's marketing campaign of Micarla de Sousa, José Ivan and the quantitative research carried out by the Office IBOPE before and during the period of HGPE. In the analysis of electoral programs, was used the qualitative and quantitative approach, taking as objective to verify whether there was some change in marketing strategy in the candidate Micarla HGPE. So the electoral programs that candidate were transcribed and analyzed and then faced with the results of researches electoral IBOPE carried out in the same period. The interview with the coordinator's marketing campaign the candidate Micarla de Sousa brought relevant information on the construction of public image at the time pre-electoral and electoral. In search of IBOPE, socioeconomic variables were regarded assex, age, education and income. With the collection of this data, there was an intersection of information about the voting intentions of Micarla candidate for mayor of Natal and it was checked how his candidacy has increased or decreased within the surveyed segments and how these oscillations marketing strategies directed at the candidate's HGPE for any specific audience. Also, do not forget that the electoral process is influenced by various factors, because this process is dynamic

Práticas clientelistas e dádivas como estratégias de hegemonia política: uma análise sobre o campo da saúde em Mossoró-RN

The reality experienced by many families and individuals who seek and require the services of the Unified Health System - SUS, the relationships between users, health professionals, and political representatives, establishes the core of the issue that guides the choice and interest of this study concerning the prominence of clientelist practices and gifts that permeate the health field. The research is based on the analysis and reflection of the intrinsic relationship between the health and political fields. It analyses the health field and its relationship with the dynamics and developments of the local political scenario relating it to the implementation of the Family Health Program and Community Health Agents Program (PACS/PSF health programs) in the city of Mossoró, State of Rio Grande do Norte which refers to the period 1991-2010; and falls into a methodological perspective of qualitative approach. The methodological tools and techniques used were based on semi-structured interviews, direct observation of the field, journalistic texts and documentary sources. The construction and questioning of the object of the research were based on theoretical contributions from authors discussing the social field and symbolic power: Bourdieu (2005); clientelist relationships and gifts from asymmetric exchanges: Rouland (1997), Lanna (1995), Martins (1999), Carvalho (1999), Diniz (1982); exercise of hegemony and political strategy from authors who analyse this subject: Gramsci (1995), Coutinho (1981), and Gruppi (1978). Furthermore, the research has established dialogues with authors who address the dynamics of Brazilian politics such as Baquero (2001) and Weffort (1993). The collected data were subjected to qualitative content analysis. The results showed that with the implementation of the PACS/PSF programs in the aforementioned city, the health field has established itself as a key scenario for the exercise of political hegemony of the factions that dominate this socio-political context, resizing clientelist practices, however, without modifying the power structures within this social scenario

Eça de Queiroz e a cozinha burguesa: literatura e alimentação

Using literature to discuss the topic of food, proper bourgeois cuisine, was the purpose of this work. As a corpus, we use one of the works of Eça de Queiroz, The City and the Mountains. Served as theoretical references the Claude Levi-Strauss s concept of universal culinary and the Jean Claude Fischler s concept of specific culinary who understands food as a cultural system which includes representations, beliefs and practices of a specific group. After the initial reading of the novel and construction of a file containing general information of the work, categories designed for elaboration of a material for analysis were these: work, characters, food, intellectuals and geographies. We realized the culinary as an epicenter for understanding the culture of a specific group: in this case, the bourgeois. We proposed a quaternary model for systematizing it: this bourgeois cuisine highlights the technique, has affection for what is rare and/or expensive but still consume it with temperance, establishing a new relationship with the use of time and, finally, it is the one that opens the ritual that involves frequent restaurants and cafes. The exercise of thinking the bourgeois cuisine through the literature suggests that the art may work on increase the comprehensive capabilities of nutritionists, professionals who deal with a complex object in your practice: the food

Limites e possibilidades do programa nacional de alimentação escolar enquanto estratégia de promoção da segurança alimentar e nutricional no municipio de Macaíba/RN

This dissertation aims to understand the importance of the National School Feeding as a strategy for ensuring the promotion of food and nutrition security in the municipality of Macaíba / RN, taking into account the implementation of the Law School Feeding, 11,947, 2009. The program was extended to all public basic education, youth and adults, in addition to ensuring that 30% of transfers from FNDE, were intended for the purchase of products from family farms. The survey was conducted with 160 students from public schools and farmers nesting Quilombo dos Palmares II, who produce on their land vegetables, fruits and cereals for their own consumption, for sale in local markets, in addition to providing for PNAE. The reciprocity between neighbors, such as mutual aid and sharing of common goods was noticeable in this group of farmers, since it was necessary to meet weekly deliveries of products to schools. As students, we applied a test of acceptability in two schools located in rural and in urban areas, to learn the opinion of ourselves in relation to school food consumed. It was concluded that to be most effective program in the region, there must be a better match in school menus, so that it can be attractive to students and to ensure greater use of fresh food, the main ingredient of same, practice of nutrition education in schools, to teach students the importance of food to health. In relation to local management, noted the need for adjustments bureaucratic as hiring staff for the departments, in order to be more agile in releasing payments to farmers, in addition to hiring assistants general services for schools, one Since the cooks exert dual role, the cooking while being responsible for cleaning the entire school environment. Government investments in the rural sector would be extremely valuable for farmers, since they need financial resources to purchase inputs, irrigation projects for gardens, availability of land for planting, transportation to facilitate the delivery of its products to schools and technical assistance more frequently

A trajetória dos movimentos socioambientais em Sergipe : personagens, instituições e estratégias de comunicação

The research aimed to study the emergence, role, and the possibilities of environmental movements in Sergipe, running through an analysis of the period between 1983 and 2011. This goal has been guided by the core issue of research, which was to analyze the relationship between the mission, structure and action of environmental organizations in Sergipe. The research arose from the need to map and critically evaluate the environmental movement in Sergipe. The methodological procedures focused on the literature search, survey papers in Sergipe a time gap of 28 years, detailed analysis of nine "movements" and selected in-depth interviews, semi-structured interviews with dozens of social actors involved in the area. In conclusion, we observed that environmentalism in Sergipe, from its inception, was associated with recovery of consciousness regarding the environment, to combat local problems of degradation, and the search for legitimacy of public opinion. Although the environmental movement have been, at times, the attention of mass media, the movement failed to leave the niche and achieve a more representative portion of society. You can still see the deep relationship between the profile of environmental leaders, capital strength and the practical results of the environmental actions and finally, it was observed that the action of the movements has much stronger bond with the relationship of the organization and its main leaders with the other "environmentalist," than with the structure and mission of the institution

Avaliação do crescimento e do custo da alimentação do pacu (Piaractus mesopotamicus Holmberg, 1887) submetido a ciclos alternados de restrição alimentar e realimentação

Avaliaram-se os efeitos da utilização de ciclos alternados de restrição alimentar e realimentação no crescimento do pacu, durante o período de engorda, e a viabilidade desta prática na produção comercial da espécie. Juvenis foram distribuídos em três tanques e submetidos a diferentes manejos alimentares, constituindo os tratamentos: A (alimentado ad libitum), B (restrição alimentar de 4 semanas, realimentado por 9 semanas) e C (6 semanas de restrição alimentar, realimentado por 7 semanas), em um total de 13 semanas por ciclo (4 ciclos experimentais). No final de cada ciclo alimentar, 20 peixes de cada tratamento foram amostrados e os dados biométricos registrados. Os valores obtidos para peso, comprimento total e fator de condição (K) foram submetidos a ANOVA e as médias comparadas pelo teste de Duncan. Os resultados mostraram que o tratamento C é o mais indicado somente para outono/inverno, promovendo maior crescimento, menor custo com ração, baixa conversão alimentar e maior receita líquida parcial. Entretanto, durante as estações mais quentes do ano (primavera/verão) outros programas de alimentação devem ser testados, utilizando-se períodos mais curtos de restrição alimentar. Quando se tratou da produção anual, o tratamento A respondeu melhor em termos de biomassa produzida, apesar do maior gasto com alimentação, visto que, com o aumento da temperatura, o crescimento dos peixes dos demais tratamentos ficou prejudicado.

Efeito da alimentação de Schizaphis graminum com genótipos de sorgo no desenvolvimento do predador Cycloneda sanguinea

O pulgão Schizaphis graminum (Rondani) (Hemiptera: Aphididae) é uma das principais pragas do sorgo. O objetivo deste trabalho foi determinar o efeito da alimentação deste inseto com genótipos de sorgo resistentes e suscetíveis no desenvolvimento do predador Cycloneda sanguinea (Linnaeus) (Coleoptera: Coccinellidae). O pulgão foi criado em folhas dos genótipos de sorgo GR 11111 e TX 430 x GR 111, resistentes, GB 3B, de resistência moderada e BR 007B, suscetível ao hemíptero. As larvas de C. sanguinea foram alimentadas diariamente, ad libitum, com ninfas e adultos de S. graminum. A duração das fases de desenvolvimento e a sobrevivência de C. sanguinea não foram influenciadas pelo genótipo. Apenas a duração do quarto ínstar, da fase larval e do período de larva a adulto foram afetadas. O peso de larvas de segundo ínstar de C. sanguinea não foi afetado pelo genótipo. Nos demais ínstares e fase adulta, esse parâmetro foi diferenciado conforme o genótipo de sorgo utilizado como hospedeiro ao pulgão. Os genótipos resistentes GR 11111 e TX 430 x GR 111 não afetam adversamente o desenvolvimento e a fecundidade de C. sanguinea, durante uma geração. Estes genótipos demonstram compatibilidade com o predador e viabilizam o manejo de S. graminum na cultura do sorgo.

Não preferência para alimentação e aspectos biológicos de Spodoptera eridania em cultivares de feijão-caupi

The aim of this paper was to evaluate the no-preference for feeding and biological aspects of Spodoptera eridania fed on cowpea cultivars BR17 Gurgueia, BRS Urubuquara, BRS Nova Era, Sempre Verde, BRS Milenio and BR3 Tracuateua. In free-choice test, leaf discs were placed in Petri dishes where one third instar larvae per cultivar was released, whereas in no-choice test one leaf disc was placed per Petri dish where one caterpillar per cultivar was released, evaluating their attractiveness after 1, 3, 5, 10, 15, 30, 60, 120, 360 and 720 minutes, as well as the leaf area consumed. Randomized blocks and complete randomized blocks design were used for free-choice and no-choice tests, respectively, with six treatments and 10 replications. The evaluation of the biological parameters of S. eridania was carried out in Petri dishes where recently hatched caterpillars were transferred in the proportion of one per dish, and the leafs of the cultivars were offered to them during the whole larval period, and we evaluated: periods and viabilities of larvae and pupae, overall viability, weight of larvae and pupae, sex ratio, longevity and overall cycle. Complete randomized design was used with six treatments and 30 replications. In no- preference for feeding free-choice test the cultivars Sempre Verde and BR17 Gurgueia were the most and the least consumed, respectively. Regarding the effects of cowpea cultivars on larval viability we can infer that BRS Urubuquara and Sempre Verde show antibiosis-type resistance to S. eridania.
