3. Self-Monitoring Microbiological Criteria for the Assessment of Hygienic Procedures During Chicken Slaughtering
ABSTRACT Self-monitoring procedures are adopted by food industries to ensure the quality and safety of final products, considering hygiene and processing criteria. This study aimed to evaluate contamination in chicken processing, considering the microbiological criteria proposed by self-monitoring systems. Environmental samples from reception, slaughtering a

4. Intervention strategies for the reduction of microbiological contamination on the hands of food handlers
Abstract The purpose of this study was to evaluate intervention strategies for the reduction of microbiological contamination on the hands of food handlers. The study was conducted from January 2009 to December 2014 at a food and nutrition company in Curitiba, Brazil. Samples from the hands of 877 handlers were collected for microbiological analysis. The int

5. The Dynamic of some Biochemical Indicators at Species of Medicinal Plants from Areas of Suceava County, Romania, Emerged under the Mining Pollution Influence
ABSTRACT It is known the fact that the mining causes huge damages on the environment having negative biologic effects extremely severe on some groups of organisms of the food chain. The pollutants causes major damages at the level of leaves' cuticles, the vegetation reacting through irreversible modifications at the tissue's level and at substances and energ

6. Changes in Soil Organic Carbon Fractions in Response to Cover Crops in an Orange Orchard
ABSTRACT The cultivation of cover crops intercropped with fruit trees is an alternative to maintain mulch cover between plant rows and increase soil organic carbon (C) stocks. The objective of this study was to evaluate changes in soil total organic C content and labile organic matter fractions in response to cover crop cultivation in an orange orchard. The

7. Process capability index Cpk for monitoring the thermal performance in the distribution of refrigerated products
Abstract The temperature of refrigerated products along the cold chain must be kept within pre-defined limits to ensure adequate safety levels and high product quality. Because temperature largely influences microbial activities, the continuous monitoring of the time-temperature history over the distribution process usually allows for the adequate control of

8. Assessing the sources of high fecal coliform levels at an urban tropical beach
Recreational water quality is commonly assessed by microbial indicators such as fecal coliforms. Maceió is the capital of Alagoas state, located in tropical northeastern Brazil. Its beaches are considered as the most beautiful urban beaches in the country. Jatiúca Beach in Maceió was found to be unsuitable for bathing continuously during the year of 2011.

9. Evaluation of glycerin as preserving agent of chicken serum for plate agglutination test
Serum is widely used for the purpose of monitoring and diagnosis support for most of poultry diseases. In the case of the serum plate agglutination test (SPA), commonly used to detect antibodies for Salmonella Pullorum (SP), Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS), serum cannot be frozen because it may result in false positive. Without fre

10. The antimicrobial efficacy of Lippia alba essential oil and its interaction with food ingredients
The objective of this study was to evaluate the antimicrobial potential of Lippia alba essential oil (EOLa) and to investigate the effect of food ingredients on its efficacy. The antimicrobial potential of the oil was determined by the presence or absence of inhibition zones, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)

11. Monitoramento temporal e espacial de contaminações bacterianas na produção de bioetanol: caracterização molecular por T-RFLP e detecção quantitativa por qPCRde comunidades formadoras de biofilmes / Temporal and spatial monitoring of bacterial contamination in bioethanol production: a molecular characterization by T-RFLP and quantitative detection by qPCR of community-formers biofilms
Bacterial contamination by Lactobacillus, Bacillus and Leuconostoc and other lactic acid bacteria is one of the main factors that affects the yield in alcoholic fermentation process. Biofilm formation protects the bacteria community and it is a permanent source of contamination. For characterization of these contaminations in (1) biofilms from centrifuge, ta

12. Desenvolvimento de um sistema de recirculação com uso de wetlands construídas para efluentes da piscicultura / Development of a recirculating system using constructed wetlands for aquaculture effluents
Global aquaculture has been growing very fast in recent decades due to several factors, including: population growth, demand for low calorie protein and especially the reduction of natural fish stocks. Brazil has enormous potential to become a world leader in fisheries production in captivity. However, the development of aquaculture in Brazil must be conduct
