This survey has to general objective to evaluate the Food Safety Policy implemented by Restaurantes Populares do Rio Grande do Norte. The survey is qualitative of type exploratory and descriptive. The universe of survey is all Units of Food and Nutrition (UAN) of the Restaurantes Populares do Rio Grande do Norte. To collects of data were used two instruments: interview and form. The interviews were intended to analyze the four axes of the Food Safety: access, food quality, production and marketing of food and organizational arrangement. The form was used to check the quality of nutrition and sanitary-hygienic food served. We used two types of forms: a spreadsheet with the weekly menu and the portions served to verify that the meals serve the nutritional needs proposed by the program; and the check-list of ANVISA to verify the sanitary-hygienic conditions in each unit. Through the survey data and analyses made observe that the access category have some problems such as lack of registration, lack of advertising of Restaurants and wastage of public resources, making policy that should be of included in a policy of exclusion. In the nutritional aspect there is neglect on the daily nutritional goal, because it is not accomplished nutritional analysis of menu offered, the nutritionists do not know what should be the nutritional value of meals served; in the hygienic-health aspect trough the problems identified is concludes that there is no guarantee of food quality hygienic-sanitary, committing the program as a Food Safety Program. About the production and marketing of food is observed some problems as: the goal of sale of meals is not achieved in full, the purchase of genres does not stimulate the local economy, nor generates jobs and income, and inefficient performance of the MEIOS's supervision. In the analysis of organizational arrangement is concluded that the partnerships are beneficial, despite some negative points, therefore, are these partnerships the problems of non-compliance, as both the MEIOS and Nutriti of important criteria established in the partnership. Therefore, it is understood that the Programa Restaurantes Populares in its original formulation is proposed to be a food safety policy, but has some problems that impossible to meet its goal, making it unprofitable like Food Safety Policy

Meat is a well accepted food with appreciable appealing. Due to its high nutritional value it plays a central role in human development. Meat/meat derivates are important sources of proteins, minerals and vitamins. Their nutritional importance is paralleled to their economic impact. Paying attention to the social alarm originated by a recent publication of WHO about the relationship between red and/or processed meat consumption and cancer, this paper reviews the following aspects: a) the present consumption of meat/meat products in Spain; b) the contribution of their macro/micronutrients to the recommended dietary allowances; c) the obliged use of additives (e.g. nitrites and nitrates) to warrant the food safety, and their daily intake. In addition health risks derived from a high consumption, as well as the most appropriate culinary uses in order to reduce the formation of toxic products (e.g. N-nitrosocompounds) are commented. Due to the huge variety of available meat products, this paper concludes that any generalization should be avoided. We also emphasize about the advantages of consuming meat/meat products in the frame of a Mediterranean diet, rich in vegetables, fruits, and bioactive compounds.

Surface Plasmon Resonance (SPR) and localized surface plasmon resonance (LSPR) biosensors have brought a revolutionary change to in vitro study of biological and biochemical processes due to its ability to measure extremely small changes in surface refractive index (RI), binding equilibrium and kinetics. Strategies based on LSPR have been employed to enhance the sensitivity for a variety of applications, such as diagnosis of diseases, environmental analysis, food safety, and chemical threat detection. In LSPR spectroscopy, absorption and scattering of light are greatly enhanced at frequencies that excite the LSPR, resulting in a characteristic extinction spectrum that depends on the RI of the surrounding medium. Compositional and conformational change within the surrounding medium near the sensing surface could therefore be detected as shifts in the extinction spectrum. This dissertation specifically focuses on the development and evaluation of highly sensitive LSPR biosensors for in situ study of biomolecular binding process by incorporating nanotechnology. Compared to traditional methods for biomolecular binding studies, LSPR-based biosensors offer real-time, label free detection. First, we modified the gold sensing surface of LSPR-based biosensors using nanomaterials such as gold nanoparticles (AuNPs) and polymer to enhance surface absorption and sensitivity. The performance of this type of biosensors was evaluated on the application of small heavy metal molecule binding affinity study. This biosensor exhibited ~7 fold sensitivity enhancement and binding kinetics measurement capability comparing to traditional biosensors. Second, a miniaturized cell culture system was integrated into the LSPR-based biosensor system for the purpose of real-time biomarker signaling pathway studies and drug efficacy studies with living cells. To the best of our knowledge, this is the first LSPR-based sensing platform with the capability of living cell studies. We demonstrated the living cell measurement ability by studying the VEGF signaling pathway in living SKOV-3 cells. Results have shown that the VEGF secretion level from SKOV-3 cells is 0.0137 ± 0.0012 pg per cell. Moreover, we have demonstrated bevacizumab drug regulation to the VEGF signaling pathway using this biosensor. This sensing platform could potentially help studying biomolecular binding kinetics which elucidates the underlying mechanisms of biotransportation and drug delivery.

Presently, the scientists recognize the health benefits of food fibers in the menu and also plant food sources are at high interest both for general population and food companies. The food companies are responsible for a clear nutrition labelling that will assist consumers to make informed and healthy choices and health providers has to inform the population about the benefits of fibers.The aim of our study was to evaluate the Romanian knowledge and attitudes regarding dietary fibers from food products. We made a qualitative survey based on a questionnaire applied in 2015, over a period of 6 months, over 670 Romanian consumers. It was focused on testing the attitudes and knowledge towards ingestion of foods rich in fibers. For all data analysis we used the software SPSS, from IBM Inc. Our results showed that the knowledge about dietary fibers and also the ingestion of food products rich in fibers were low, and most of the subjects didn’t have any interest to read the nutritional information from food labels. The female participants ate more whole grains and fruits than males and pay more attention to food labelling. Romanian people prefer to stay and eat home than at restaurants especially in rural areas, and the knowledge about fibers benefits was significantly related to education and urban location. We underline the needs for more efficient community interventions and proper information about the importance of dietary fibers for our health and also to improve and disseminate nutritional standards and diet recommendation among population.

The PARABAN project has been a Scotland-wide initiative to develop and deliver farm-specific ‘best practice’ for the control of Mycobacterium avium ssp. paratuberculosis (MAP) in cattle using ‘Knowledge Exchange’. A range of partners have been involved, including nine ‘Champion Farms’. With input from the farmer, his/her vet and PARABAN advisors, a tailored monitoring and control programme was devised for each ‘Champion Farm’, taking into account the history of the disease on the farm, the physical facilities available and farmer objectives. Culling decisions based on live animal test results were incorporated into each farm-specific programme to complement the management programme already in place to maintain each herd. Results were analysed and discussed with all the partners throughout the project and then offered for wider scrutiny at farm open days. Feedback and questions from these open days have been used to complete the ‘Knowledge Exchange’ cycle. As a major component of the PARABAN project the author collected samples from all adult animals culled from ‘Champion Farms’ at slaughter or as fallen stock, irrespective of in-life MAP test status. These were then subjected to histopathological examination by experienced veterinary pathologists and the results compared with the results from in-life MAP testing. This was intended to evaluate the contribution slaughterhouse sampling could make towards decision making for disease control on farm and formed the main aim of this thesis. In total, samples of terminal ileum and draining lymph node were collected from three-hundred and fifty-two animals. A positive result on histopathology was defined as the presence of lesions typical of MAP and also the presence of acid-fast bacteria within the sections. There was found to be fair agreement between the overall results from histopathology and serum ELISA (Kappa = 0.33), though there appeared to be some variation in agreement between the tests on the individual ‘Champion Farms’. The presence of MAP was confirmed in seven of the eight farms which contributed animals to this study, despite sometimes prolonged efforts at controlling the disease. A separate study was undertaken to make use of the archives of the Scottish Centre for Production Animal Health and Food Safety at the Veterinary School, University of Glasgow. The archive contained records of cases from across southern Scotland and northern England. Analysis of the data generated from examination of these records suggested that MAP is widespread within the Scottish cattle herd and may well be increasing

Introducción: Actualmente existe un reconocimiento creciente de que el hogar desempeña un papel importante en varias cuestiones de higiene y salud pública. El ambiente del hogar ha sido implicado como una fuente importante de propagación de enfermedades infecciosas, y la intervención de las medidas de higiene, implican una reducción de la incidencia, especialmente en los países menos desarrollados y en poblaciones vulnerables como las gestantes. Objetivo: Evaluar la asociación entre la práctica de hábitos higiénicos de las gestantes estrato 1 y 2 de las localidades de Usaquén y Kennedy en relación a sus factores socioeconómicos. Métodos: Estudio Analítico de Corte transversal. Se realizó en las gestantes de los estratos 1 y 2 de las localidades de Usaquén y Kennedy en la ciudad de Bogotá. Se recolectaron datos referentes a factores socioeconómicos y hábitos de higiene de 141 gestantes a través de la aplicación de una encuesta. Los datos obtenidos de las variables de interés fueron procesados a través de análisis multivariado y regresión logística paramétrica y no paramétrica, con el fin de establecer si existía asociación o no entre las mismas. Resultados: Existe asociación entre el número de Nacidos vivos y la presencia de plagas (p=0.034 y Coeficiente de correlación: -1.253). Así mismo se encontró asociación habitar en cuartos rentados y la limpieza de casa general (p=0.008 y Coeficiente de correlación: 0.480). Existe una asociación entre la variable edad y el lavado de frutas (p=0.041 y Coeficiente de correlación: 0.384). Conclusiones: Existe relación entre los hábitos higiénicos y los factores socioeconómicos de las gestantes estudiadas. Existe un mayor hábito de lavado de frutas antes de ser consumidas en gestantes de mayor edad. Adicional a esto se evidencia a mayor número de hijos hay menor presencia de plagas en el hogar y mayor limpieza del hogar. Solo en un pequeño porcentaje de los hogares se evidencio una óptima limpieza, por lo cual se deben plantear más políticas para mejorar la higiene de los mismos ya que los datos reportados permanecen subóptimos en la población seleccionada.

Las organizaciones de hoy en día entienden más el valor de las personas dentro de estas, por ser el elemento dinamizador. Por esto es necesario transmitirles constantemente la visión, misión y objetivos de la empresa para que las personas contribuyan a este fin. Dado el reconocimiento por parte de las organizaciones hacia el recurso humano y su administración, se hace necesario la existencia de un liderazgo bastante eficiente que sea capaz de asegurar condiciones favorables de trabajo y que garanticen el cumplimiento de los objetivos de las empresas. Las organizaciones del Siglo XXI exigen líderes con cualidades, habilidades y actitudes para afrontar todos los factores externos con los que se pueden enfrentar. Es por eso que surge la necesidad de estudiar la empresa Lácteos El Pomar ya que es una empresa que resurgió de las cenizas después de haber entrado en liquidación y que tiene como referente de un líder al gerente de la compañía. El propósito de este estudio de caso será describir y analizar el liderazgo y la motivación como herramientas transformadoras en la nueva gerencia de Lácteos El Pomar, como también entender cómo estas se implementaron e influenciaron al grupo de trabajadores para salir de la crisis. Mediante este estudio de caso se espera comprender si el gerente de la empresa es percibido como líder e identificar su estilo de liderazgo. Por otro lado, mediante entrevistas al personal de la empresa, se esperará identificar los factores que influyeron de manera negativa para acentuar la crisis de la compañía. Finalmente se espera analizar aquellas estrategias de liderazgo realizadas por la dirección que conllevaron a la permanencia de la compañía a pesar de la crisis.

Actualmente la relación que existe entre la logística humanitaria y la seguridad agroalimentaria es muy estrecha, estos dos conceptos constituyen un elemento sumamente importante en situaciones que se presentan hoy en día a nivel mundial, como por ejemplo en los diferentes tipos de desastres naturales como terremotos, tsunamis, sequías, hambrunas, entre otros, o simplemente, en zonas de alta pobreza. La logística humanitaria es hoy en día un concepto novedoso que nace de la necesidad de poder suministrar los recursos adecuados en zonas que han sido afectadas por desastres naturales, o situaciones de orden público, como por ejemplo los conflictos armados. Estos recursos deben asegurarle a la población afectada que puedan mantener a lo largo de un tiempo sus necesidades básicas, y así mismo, que estos recursos aseguren a la población afectada que puedan tener una vida digna y segura, lo que conlleva entre otras cosas, tener una seguridad agroalimentaria. A medida que se presentan diferentes escenarios de desastres naturales, la ayuda humanitaria a nivel mundial es necesaria, y el tiempo de respuesta juega un papel sumamente importante. En consecuencia, esta investigación presenta un enfoque que involucra los conceptos de logística humanitaria y de seguridad agroalimentaria, con el fin de contextualizar su evolución y los estudios que se llevan a cabo hoy en día.

Meat industry needs to reduce salt in their products due to health issues. The present study evaluated the effect of salt reduction from 6% to 3% in two Portuguese traditional blood dry-cured sausages. Physicochemical and microbiological parameters, biogenic amines, fatty acids and texture profiles and sensory panel evaluations were considered. Differences due to salt reduction were perceptible in a faint decline of water activity, which slightly favoured microbial growth. Total biogenic amines content ranged from 88.86 to 796.68 mg kg 1 fresh matter, with higher amounts, particularly of cadaverine, histamine and tyramine, in low-salt products. Still, histamine and other vasoactive amines remained at low levels, thus not affecting consumers’ health. Regarding fatty acids, no significant differences were observed due to salt. However, texture profile analysis revealed lower resilience and cohesiveness in low-salt products, although no textural changes were observed by the sensory panel. Nevertheless, low-salt sausages were clearly preferred by panellists.

Environmental pollution by several heavy metals and metalloids is a severe problem worldwide, as soils became increasingly contaminated, posing a threat to ecosystems and ultimately to human health. Contamination derives from large scale urbanization and industrialization, threatening land ecosystems, surface and groundwater, as well as food safety and human health. Remediation strategies for heavy metal-contaminated sites are necessary to protect from their toxic effects and conserve the environment for future generations. Numerous physicochemical techniques have been adopted including excavation and deposition in landfills, thermal treatment, leaching and electro-reclamation. These techniques are fast but inadequate, costly, cause adverse effects on soil physical, chemical and biological properties, and may lead to secondary pollution. In fact, many of these approaches only change the problem from one form or place to another, and do not completely destroy the pollutants. There was an urgent need to develop new technologies which are cost-effective and eco-friendly. In this context, biological remediation has tremendous potential. It uses plants and microorganisms to remove or contain toxic contaminants and is considered as the most effective method because it is a natural process, environmentally-friendly, has a low cost, and wide public acceptance. The present chapter aims to provide a comprehensive review of some of the promising processes mediated by plant and microbes to remediate metal-contaminated environments. Some biological processes used for the decontamination of organic compounds will also be included because of their relevance and potential common use for both purposes.

Fungal endophytes present in different asymptomatic grapevine plants (Vitis vinifera L.) located in different vineyards within Alentejo, a highly important viticulture region in Portugal, were identified in this study. Sampled grapevine plants included the three most representative cultivars in the region, Syrah, Cabernet Sauvignon, and Aragonez, growing under two different modes of management, conventional and biological. Sixteen fungal taxa were identified through sequencing of the internal transcribed spacer region. Total number of endophytic fungi isolated showed significant differences both in management mode and in cultivars, with higher numbers in grapevines under conventional mode and from Syrah cultivar. The composition of fungal endophytic communities did not show significant differences among cultivars, but differences were observed between fungal communities isolated from grapevines under biological or conventional modes. The most fungal taxa isolated from grapevines cultivated under biological mode were Alternaria alternata, Cladosporium sp., and Nigrospora oryzae, and under conventional mode Botrytis cinerea, Epicoccum nigrum, and Epicoccum sp. These differences suggest that the different products used in grapevine production have impacts in fungal endophytic composition. Further investigation of the identified fungi with respect to their antagonistic characteristics and potential use in plant protection to ensure food safety is now in course.
