1. Some Quality Parameters of Powdered Soups Prepared from Different Fish Species
Abstract In this study, we aim to determine the shelf life of dried and ready to use-powdered soup samples obtained from different types of fish species such as Rainbow trout (Oncorhynchus mykiss), sea bream (Sparusaurata L.) and sea bass (Dicentrarchuc labrax). For this purpose, the chemical (moisture, protein, fat, carbohydrate, ash, pH, Thiobarbituric ac

4. Effect of brine and dry salting methods on the physicochemical and microbial quality of chub (Squalius cephalus Linnaeus, 1758)
Abstract The present study, looks at the physicochemical and microbiological quality changes that occur due to different salting techniques (20% salt concentration) of chub (Squalius cephalus) and when stored in 4 ± 0.5 °C. Samples of fish from each group was taken on the 15, 30, 45, 60, 90 and 120th day and was analyzed for nutritional component (crude pr

5. Microalgae population dynamics in photobioreactors with secondary sewage effluent as culture medium
Nitrogen and phosphorus present in sewage can be used for microalgae growth, possibiliting cost reduction in the production of microalgae at the same time that it decreases the eutrophication potential of the effluent. This research aimed at monitoring the native community of microalgae and coliform bacteria in a secondary effluent from anaerobic municipal s

6. Elimination of coliforms and Salmonella spp. in sheep meat by gamma irradiation treatment
This study aimed at evaluating the bacteriological effects of the treatment of sheep meat contaminated with total coliforms, coliforms at 45 °C and Salmonella spp. by using irradiation at doses of 3 kGy and 5 kGy. Thirty sheep meat samples were collected from animals located in Rio de Janeiro State, Brazil, and then grouped in three lots including 10 sample

7. Acetic acid as an intervention strategy to decontaminate beef carcasses in mexican commercial slaughterhouse
Beef can be contaminated during the slaughter process, thus other methods, besides the traditional water washing, must be adopted to preserve meat safety. The objective of this study was to evaluate the effect of 2% acetic acid interventions on the reduction of indicator bacteria on beef carcasses at a commercial slaughterhouse in Mexico. Reduction was measu

8. Avaliação das condições higiênico-sanitárias de abates de suínos no Estado da Paraíba / Evaluation of sanitary conditions in slaughterhouses in the state of Paraiba
The physical structure of slaughterhouses, sanitary-hygienic practices and microbiological parameters related to pork quality were assessed. Five slaughterhouses in the state of Paraíba were inspected, using a checklist and were classified into group I (low risk), II (intermediate risk) and III (high risk). The microorganisms investigated were: in water: to

9. Water quality and diversity of yeasts from tropical lakes and rivers from the Rio Doce basin in Southeastern Brazil
Yeast communities were assessed in 14 rivers and four lakes from the Doce River basin in Brazil, during the rainy and dry seasons of the years 2000 and 2001. Water samples were collected at the subsurface in all sites. The following physical and chemical parameters were measured: temperature, dissolved oxygen, pH, electrical conductivity, total phosphorus, o

10. Microbial contamination of luncheon meat sliced and packaged at supermarkets in Porto Alegre, Brazil
Background: Ready-to-eat (RTE) foods are considered a high risk food group, since they are often consumed without a cooking step. Luncheon meat, a RTE food widely consumed in Brazil, is traditionally produced as industrially vacuum-packaged loaves and afterwards is sliced and re-packaged at retail stores. Since this practice may pose an additional hazard of

11. Effect of the litter material on drinking water quality in broiler production
Considering the importance of drinking water and its effect on broiler performance, drinking water quality was studied using six different litter materials. The presence of coliform bacteria and Escherichia coli was investigated. The following litter materials were used in the trial: wood shavings, rice husks, chopped Napier grass (Pennisetum pupureum), 50%

12. Avaliação da utilização de colifagos como indicadores virais a partir da análise de enterovírus e adenovírus em efluentes tratados por diferentes processos biológicos
Domestic sewage contains a high amount of bacteria and other pathogens and non pathogens that are discharged into water bodies. Contamination of water by the presence of pathogenic bacteria and viruses, brings undesirable consequences, especially for public health. The objective of this work was to evaluate the possibility of using analysis of coliphages as
