Abstract The aim of this study was to analyze the microbiological quality of meals served in nursing homes in the city of Ponta Grossa, Paraná, before and after the training of food handlers. The first stage was to perform a checklist conforming with current legislation. The second consisted of the collection of 4 food samples from each location and a microbiological investigation in accordance with the relevant legislation. The third was the training of food handlers in relation to good food handling practices. The fourth was a further microbiological analysis of new samples. The application of a checklist showed that the locations met the requirements of current legislation. Of the 40 samples analyzed, 17.5% (7 samples) were unfit for consumption. Among the unfit samples 15% (6 samples) had coliforms at 45 °C, 2.5% (1 sample) had coagulase-positive staphylococci, 2.5% (1 sample) had Bacillus cereus and 2.5% (1 sample) had Salmonella sp. The results of this study show the importance of controlling the quality of food served to an age group that is prone to health risks.

A cidade de Uberlândia, MG, vem apresentando um processo de urbanização acelerado, com crescimento populacional de 3,54% ao ano, acima da média nacional. Entre os problemas causados pela urbanização está o fornecimento de hábitats para uma grande variedade de insetos. Neste estudo objetivou-se identificar espécies de formigas que ocorrem nos domicílios de Uberlândia, relacionando-as ao tempo de urbanização e infra-estrutura dos bairros e ao estado de conservação das residências. As formigas foram coletadas utilizando isca-armadilha em 120 residências de 12 bairros reunidos em três grupos. Registraram-se 14 espécies de formigas, sendo Camponotus (Mayr), Monomorium (Mayr) e Tapinoma (Foerster), respectivamente, os gêneros mais freqüentes. Somente Camponotus vittatus (Forel), Monomorium pharaonis (L.), Tapinoma melanocephalum (Fabricius) e Brachymyrmex sp. (Mayr) foram coletadas nos três grupos. A relação entre as formigas mais freqüentes no interior dos domicílios e seu estado de conservação mostrou que Paratrechina longicornis (Latreille) foi mais freqüente (60%) em construções mal conservadas ou precárias. C. vittatus e Camponotus melanoticus (Emery) ocorreram em locais que correspondem às três categorias de estado de conservação. C. vittatus foi a espécie de formiga mais freqüente nessa área urbana de Cerrado, o que não foi encontrado em nenhum outro levantamento publicado sobre formigas urbanas.

Uberlândia, MG, Brazil, underwent an accelerated process of urbanization with a population growth of 3,54% each year, higher than the national average. One of the problems emergent from urbanization is the use of different habitats for a great variety of insects. The objective of this study was to identify species of house-invading ants that occur in the urban area of Uberlândia. The occurrence of the house-invading species in regard to the time of urbanization, neighborhood infrastructure, age and maintenance of private houses was also assessed. The ants were collected using bait-traps in 120 residences from 12 neighborhoods which were put in three groups. Fourteen species of ants were catalogued, with Camponotus (Mayr), Monomorium (Mayr) and Tapinoma (Foerster) being the most frequent genera. Only Camponotus vittatus (Forel), Monomorium pharaonis (L.), Tapinoma melanocephalum (Fabricius) and Brachymyrmex sp. (Mayr) were collected in all three groups. The relation between the ants collected and the age and maintenance of the private houses showed that Paratrechina longicornis (Latreille) was most frequent (60%) in poorly preserved or precarious constructions. Whereas, C. vittatus and Camonotus melanoticus (Emery) occurred in all categories of maintenance. Overall, C. vittatus which had not been found in any previously published survey of urban ants, was the most frequent species in urban areas of the Cerrado.
