Item Análise parasitológica de cultivares de uvas (Vitis spp.), comercializadas em diferentes locais na cidade de Serra Talhada, Pernambuco(2024-03-07) Cavalcanti, Amanda de Brito; Lima, Marilene Maria de; http://lattes.cnpq.br/9135077184593725; http://lattes.cnpq.br/2411545060419950Currently, there is an increase in the consumption of fresh foods due to the population's growing search for a healthier diet. However, the quality of these foods in terms of microbiological health is a concern, as they may represent a significant means of transmission of enteroparasites. The present study aimed to investigate the occurrence of parasites in grape samples, sold in different locations in the city of Serra Talhada. The collection period took place between July and December 2023, with the analysis of grape samples (Vitis spp.) carried out at the Plant Biotechnology Laboratory, at the Federal Rural University of Pernambuco. In total, 28 samples of grapes were analyzed from 14 commercial establishments, including greengrocers, street markets and supermarkets. Of the samples analyzed, parasitic structures such as insects, mite eggs and mites were found. Given the results obtained, it was concluded that parasitic structures are present in grapes sold in the city of Serra Talhada, however additional studies are necessary, expanding the sample size and using more than one diagnostic method.Item Uso de agrotóxico na agricultura familiar ás margens do rio Pajeú no município de Calumbi no sertão pernambucano(2020) Araújo, Anderson dos Santos; Almeida, Rosa Honorato de; http://lattes.cnpq.br/4319299572657528Family agriculture in Brazil accounts for 70% of all food consumed in the domestic market, however, the difficulty of access to information and the lack of technical assistance has promoted the excessive use of pesticides. In Pernambuco, there are about 6,619 tons of pesticides used annually and an average of 1545 cases of intoxication between 2002 and 2014. In view of the above, the objective of the present study was to conduct a survey of the profile of riverine family producers regarding the use of agrochemicals and safety procedures during their use. The study was carried out in the Sertão do Alto Pajeú region of Pernambuco, in the municipality of Calumbi, with family farmers located on the banks of the Pajeú River. The data were collected from the application of an oral questionnaire, subdivided into three themes: 1- Cultures worked; 2- Agrotoxic used and 3- Personal protective equipment. A total of 25 family farmers were interviewed and the choice of farmers was made according to the best profile of family farmer and proximity to the banks of the Pajeú River. This study reveals an important social and environmental problem, which is reproduced in several rural areas of the country, within the context of food production by family agriculture. A significant portion of the farmers interviewed were found to use agrochemicals, which are not recommended for crops and classified as very dangerous to the environment, also highlighting the non-use of IPEs. If these family farmers had the opportunity and technical guidance, access to information and government incentives, the reality presented in this research could be different.Item Caracterização físico-química e microbiológica do queijo coalho, com e sem registro, comercializado durante o período seco e chuvoso na cidade de Serra Talhada-PE(2019) Souza, Mailza Gonçalves de; Silva, Fabiana Maria da; http://lattes.cnpq.br/3782949109950763; http://lattes.cnpq.br/8159251448025679Much appreciated by consumers, curd cheese is produced in an industrial, artisanal and informal way, which can make available to the population a product with or without nutritional and microbiological quality. Thus, the objective was to analyze the physicochemical and microbiological characteristics of curd cheese, with and without registration sold during the dry and rainy season in the city of Serra Talhada-PE. Twenty samples of rennet cheese were acquired at the different commercialization points of the city and in two different periods (dry and rainy), ten were registered cheese and ten without registration. A completely randomized design with 2x2 factorial design (two periods, rainy and dry and cheeses with and without registration) was used. The results were subjected to analysis of variance and Tukey test at 5%, using the Minitab version 16.2.3 program. In the physicochemical analyzes, the pH, acidity, fat, mineral matter and humidity did not differ statistically (p> 0.05 ), but there was a difference for the temperature (p <0.05), being the average of the cheese without and registered in the dry and rainy period of 19, 20, 8, and 13° C respectively. The protein presented statistical difference for the two studied variables (periods and registration), being the averages for the cheese with and without registration, in the dry and rainy periods of 20,43%, 21,20% 25,665 and 23,30%. . Of the cheeses registered, 90% of the analyzed samples, in the dry and rainy period, presented positive results for the presence of thermotolerant coliforms. For unregistered cheese, 100% of the samples were contaminated in both periods analyzed. For the presence of Salmonella, cheeses registered at 20% were contaminated with the bacteria. In the rainy season, 60% of the unregistered cheeses were positive, while 80% of the samples had contaminated cheeses. The result for Staphylococcus aureus analysis was negative in 100% of the samples in both periods analyzed. The rennet cheese sold in the municipality of Serra Talhada, presents contamination by microorganisms that can cause serious damage to the health of consumers, in addition to improper storage temperature.Item Avaliação de milho (Zea mays) e feijão-caupi (Vigna unguiculata) em solo (neossolo litólico) contaminado com Al(III) através de análise morfológica e espectrofotométrica(2019) Silva, Maria Caroline Pereira da; Lima, Marcelo Batista de; http://lattes.cnpq.br/2424699316257149; http://lattes.cnpq.br/2844991714013250Aluminum in its ionic form, Al (III), presents itself as a problem for the development of plant cultures and has been pointed as a potential factor for the emergence of neurodegenerative and bone diseases in humans. In this work we evaluated the influence of different Al (III) concentrations on soil samples (eutrophic cambisol) and corn (Zea mays) and cowpea (Vigna unguiculata) crops. This evaluation was made by the morphological and spectrophotometric analysis of the plants and by the analyzes by the titulometric and spectrophotometric method for the soil. Thus, a planting was performed for 21 days. The seed containers, three corn or three bean, were arranged in eight blocks, each block containing all soil samples treated with different Al (III) concentrations. After the germination and growth period, the crops and soil were analyzed. The main symptoms of morphological alteration observed in the plants were chlorosis, leaf curling and reduction in the root system and size. The spectrophotometric analysis of the plants resulted in Al (III) concentrations between 167.58-181.26 mg L-1. The analyzes performed on soil samples for Al (III) concentration by both methods presented different values. The titration method showed variations between 16.19-59.36 mg L-1 of Al (III), while in the spectrophotometric the values obtained were between 168.24-230.77 mg L-1 of Al (III).
