Espectro de agentes etiológicos associados a surtos de doenças transmitidas por alimentos em núcleos receptores turísticos de três regiões geográficas do Estado de São Paulo

Foodborne and waterborne diseases are spread by the consumption of food or water contaminated with bacteria and/or their toxins, viruses, parasites or chemicals. The aim of the research reported here was to establish the spectrum of etiologic agents of foodborne outbreaks at 15 tourist resorts in three geographic regions of the State of Sao Paulo (Brazil). The study was based on the cases reported to the Epidemic Surveillance Center (CVE) of the Public Health Authority of the State of São Paulo (SES), from 2002 to 2005. The tourist centers were chosen at random in three regions of the state (Capital, Interior and Coast) and offered the following attractions: events, agribusiness, cultural history, shopping, town center, gastronomy, health and leisure, sun and sea. Among the bacteria, the results showed that Salmonella spp. were most frequently associated with outbreaks, followed by Shigella spp., enterotoxigenic Escherichia coli, Staphylococcus aureus, Clostridium perfringens, Bacillus cereus and Campylobacter spp. Viruses (Rotavirus and Hepatitis A) played a part in many of the cases, while the frequency of parasites and worm infestations was low in the foodborne disease outbreaks at these resorts. The mixed foods (rice, beans, liver, potatoes, barbecue, juice), fish and poultry were the three commonest vehicles implicated in the outbreaks.

Avaliação preliminar do potencial turístico do município de rifaina (SP) e os impactos decorrentes do uso público de seus atrativos paisagísticos

This paper attempts to assess both the touristic potential of scenic attractions and the environmental impacts resulting from the public use of such attractions in the Rifaina Municipality, State of São Paulo, Southeastern Brazil. In the recent past, this municipality had its economy concentrated in rural activities (livestock, corn, rice and bean crops) and in the ceramic industry (production of bricks, tiles and shackles),which was largely developed in the floodplain of the Rio Grande before the construction of the Jaguara Power Plant Dam. The impacts resulting from touristic activities were evaluated by applying the VIM - Visitor Impact Management method, with emphasis on biophysical indicators. The main touristic attractions analyzed were: (1) Rifaina artificial beach; (2) Jaguara Reservoir; (3) Morro do Chapéu (scenic hill); (4) Touristic railroad; and (5) Cuestas cliffs. Attractions (1) and (2) are the most exploited ones, including, in the second case, nautical sports, sportive and craft fishing, and summer lodging. Although currently disabled, the touristic railroad presents potential conditions to be re-explored. Attractions (3) and (5), despite keeping high landscape and ecological ecotouristic potential, are the least visited places. In the present paper, a preliminary characterization of the major issues of tourism industry in the Rifaina municipality is made, including suggestions for the sustainable exploitation of tourism resources. The final results of the environmental impact evaluation of the tourism activities include small impacts in attractions (4) and (5) and moderate impacts to the three first attractions. In order to keep the sustainable touristic potential for that municipality this study proposes the improvement of the following measures: to foster research projects on technical or scientific aspects of the touristic attractions, improvement of tourism infrastructure and the creation of an Environmental Protection Area (APA) of the cuestas' scarps.

Análise multivariada na determinação do risco de erosão em solos sob irrigação

The objective of this work was to verify the application of cluster analysis to evaluate soil erosion risk for different soil classes, soil slopes and soil managements. The study was conducted in a 33 ha section of a large field located in Carmo do Rio Claro County, MG, Brazil. The field had been managed in a corn/bean rotation under conventional tillage and under coffee plantation for seven years, both under sprinkle irrigation. Soil samples were obtained at every 10 m at 0.20 m depth along a transect of 1050 m. Soil erosion risk (A), natural potential erosion (PN), and erosion expectation (EE) were determined and submitted to a cluster and principal component analysis. The application of clustering analysis showed high correlation between the clusters and soil types. With clustering analysis plus principal components analysis, it was possible to identify groups of high and low soil erosion expectation, showing that the areas with higher soil erosion expectation are correlated to the soil class, soil slope and soil management. Among the studied variables, the natural potential erosion (PN) showed to be the most important factor to identify different soil erosion groups. The cluster analysis showed that 98% of the variables were classified within each group, and that they should be managed differently due to the soil erosive potential of each group,.

Supressão de água em diferentes fases fenológicas do feijoeiro (Phaseolus vulgaris L.)

Bean (Phaseolus vulgaris L.) is widespread in the Brazilian social and economic scene. The hypothesis is that if the water supply is suppressed in just one of the five development stages of irrigated beans, it can result in yield reduction lower than 20%, allowing water economy. The objective of this study was to compare the performance of bean Carioca group IAC Alvorada yield components, with irrigation suppression in each of the five phenological phases (emergence, vegetative, flowering, grain filling and maturation) and no irrigation and irrigated in all stages. The study was conducted at Agronomical Sciences College, UNESP, Botucatu, SP, Brazil. The statistical design was the randomized block with seven treatments and four replications. Data were subjected to analysis of variance and t test at 5% probability. A rainfall event (58 mm) after planting allowed the successful emergence of seedling beans in plots where water would not be applied. The yield components were higher affect when there was irrigation's suppression at Vegetative phase and at Flowering phase. The treatments where occurred irrigation suppression at Maturation and at Emergence showed yield reduction of less than 20%, proving the hypothesis.
