RESUMEN

RESUMO Nascentes localizadas em locais públicos, como praças e parques, frequentemente são utilizadas pela população como fonte alternativa de água, o que pode colocar em risco a saúde pública quando não há qualidade adequada para consumo. O objetivo deste trabalho foi avaliar a água das bicas localizadas em três parques públicos da cidade de Curitiba, Paraná. O monitoramento foi realizado mensalmente por meio de de análises microbiológicas de coliformes totais (CT), Escherichia coli (EC) e bactérias heterotróficas (BH), e tomadas de pH, com coletas em triplicata durante um ano em três pontos: Parque Atuba (A), Parque Gutierrez (B) e Parque São Lourenço (C). Os resultados mostraram contaminação por CT no ponto A, em B foi observado presença em níveis elevados em todas as coletas de CT(log 2,4350±0,6730 NMP.100 mL-1), EC (log 1,0890±0,6327 NMP.100 mL-1) e BH (log 1,9170±0,6920 UFC.mL-1), não sendo observadas diferenças significativas entre os períodos de coleta (p>0,05). Foi evidenciado que nos períodos chuvosos a condição de potabilidade da água decaiu em todos os pontos avaliados, com aumento significativo na contagem de CT seguido pelo acréscimo de BH, sugerindo infiltração nas nascentes canalizadas. A presença constante de EC no ponto B sugere contaminação por esgoto, o que pode colocar em risco a saúde das pessoas que consomem a água disponível nas bicas.


ABSTRACT Water sources in public places like parks and squares are often used by people as an alternative for available water, which might be a public health concern when there is no adequate quality for consumption. The aim of this study was to evaluate the water quality from the fountains located in three public parks in Curitiba, Paraná, Brasil. The monitoring was conducted monthly by microbiological analysis of total coliforms (TC), Escherichia coli (EC) and heterotrophic bacteria (HB) and the pH was taken, with triplicate samples during a year at three sites: Atuba Park (A), Gutierrez Park (B) and São Lourenço Park (C). The results showed TC in site A; at B it was observed the presence, at high levels, of TC (log 2.4350± 0.6730 NMP.100 mL-1), EC (log 1.0890±0.6327 NMP.100 mL-1) and HB (log 1.9170±0.6920 UFC.mL-1), significant differences among sampling periods were not observed (p>0.05). It was observed that in the rainy season the condition of water portability decreased in all evaluated sites with a significant increase in TC, followed by increasing of HB, suggesting infiltration in the channeled sources. The presence of E. coli in site B suggests wastewater pollution, which can endanger the health people consuming the available water in the taps.

RESUMEN

The purpose of this study was to evaluate the microbiological quality from the drinking fountains of a Public Institution located in the state of Parana, Brasil, as for the presence of total and faecal coliforms. Were analysed water samples of drinking fountains from two Institution campi, based on the determination of the presence of total and faecal coliforms through the use of the Colilert Technique. The results revealed that one sample of water from one of the drinking fountains analysed revealed bacteria contamination belonged to the total coliform group, corresponding to 1 bacteria/ IOOmL of water None of the samples analysed revealed contamination belonged to the faecal coliforms group.

O objetivo do estudo foi avaliar a qualidade microbiológica de bebedouros de uma Instituição Pública do Paraná quanto à presença de coliformes totais e fecais. Foram analisadas amostras de água de bebedouros de dois campus da Instituição, com base na determinação da presença de coliformes totais e fecais por meio da técnica do Colilert em cartela. Os resultados revelaram que uma amostra de água de um dos bebedouros analisados apresentou contaminação com bactéria do grupo coliforme total, correspondente a I bactéria/lOO mL de água. Nenhuma das amostras analisadas apresentou contaminação pelo grupo dos coliformes fecais. (AU)

RESUMEN

In view of the need to in form the producers, dealers and consumers about the capability of the vegetables in being a vehicle for microorganisms, they should receive suitable hygienic and sanitary treatment. This paper aimed at evaluating the microbiological quality of organic and conventional tomatoes (Lycopersiconesculentum Mill.) commercialized in Curitiba city, southern Brazil. Eight samples of conventional tomatoes and four samples of organic tomatoes were collected from different sites. The microbiological analyses for detecting Salmonella spp and molds and yeasts were conducted according to the Compendium of Methods for Microbiological Examination of Foods. Total coliforms and Escherichia coli were analyzed by the PetrifilmTM methodology. The data were analyzed by variance analysis and Tukey tests. No Salmonella sp was isolated from 25 g of tomato samples. The total coliform counts ranged up to 1.4x103CFU/g and Escherichia coli up to 2.3x102 CFU/g in conventional tomatoes. Yeasts and molds were foundin conventional tomato samples up to 2.1x10, and up to 1.04 x 1012 CFU/g in organic tomato samples. This study clearly shows that the tomatoes ought to receive suitable hygienic and sanitary treatment before being commercialized.
