The quantity of available water in the planet, being in superficial or in-depth collections, it is enough to assist the needs of the globe population. Problems exist related to the distribution of natural reservoirs and the population density, since there is not equivalency between the quantity of the available water and the populational density. Besides, poor use and undesirable attacks to the water source has turned the planet potable water into improper for its use in the natural form. The water is indispensable for everything and everyone: the food chain, agriculture and cattle and even for tourism and leisure. Of all the available sources, the underground sources are the ones that offer the highest quality, for that reason they are much used by human consume and industrial production, being food, medication, and general use. The current essay of major completion (TCC) has as its purpose to analyze the physio chemical and microbiological characteristics of the potable water used for the consume of employees of a public company of the state of Pernambuco, based on the evaluation of the implemented good practices, as well as the implementation of the APPCC system. The water used by the company is from an underground source, from a crafted well. From the months of July to November of 2020 there were analyzed documents related to the physio chemical and microbiological parameters: heterotrophic bacteria, total Coliforms and Escherichi coli, accordingly, to validated methods by SMWW. The results showed macrobiotic load in the researched points and in the 3 kinds of analyzed microorganisms (˂1.0 to 7.9x10 UFC/mL to heterotrophic; ˂1.0 CFU/mL to Total Coliforms and ˂1.0 CFU/mL to E. coli) much inferior to the maximum allowed by the current legislation, which is 500 UFC/mL, absence/100mL and absence/100mL, respectively. As for the physical and pH parameters, it was observed variations: pH=5.3 to 6.6; Color= 10 to 44uH; Turbidity= 1 to 8 UT and Free residual chloride= 0.02 to 0.66mg/L. These results allowed to conclude that: in every analyzed data and during the period that was studied, the water used in the company fits the potability standards for the physio chemical and microbiological parameters; the used water treatment in the public company of the state of Pernambuco, consisting of the disinfection, filtration, stocking and distribution steps, is enough to support and guarantee the water quality; observed inconstancies in the physio chemical parameters of the pH, color, turbidity and free residual chloride did not compromise the quality of the water for human consumption stablished by the 2914 regulation from 12/12/2021.

Brazil produces around 10 million tons of beef, from which approximately 20% are exported to other countries following rigorous quality standards. High-quality food is an important factor in its consumption. The goal of this research was to verify if current legislation for slices of beef exposed in supermarkets of Camaragibe city is being enforced correctly. Especially in terms of temperature conditions in the beef storages according to the legislation, and to present suggestions to enhance these conditions to minimize the issues found. It has been selected a sample of five sale points, where was collected six pieces of beef from each supermarket. It has been considered two types of cuts (“patinho” and “peito”). Hence, in total 30 meat samples, which were packed using high-density polyethylene plastic, i.e., following the same conditions as offered to regular customers. To evaluate the temperature conditions, it was used a portable multi-function digital thermometer with a metallic rod and -50ºC to 300ºC measurement capacity. Two out of five sites had visible thermometers and exposed enough pieces in the glass case. In regards to the temperature conditions of the beef, only one site has followed the regulations of the “regulatory standard n° 4/2014 – DIVISA/SVS/SES”. Therefore, only six out of the 30 samples have followed the current regulations of ideal temperature for refrigerated meat. The results allowed us to identify the need for the enforcement of best practices, assessment systems, and training programs to employees, as well as the means to certify the production chain of refrigerated meat. It has been suggested the deployment of the APPCC system on the manipulation and exposition of refrigerated meat, which is to be adopted by every stakeholder of the production line.

The chicken meat production in Brazil surpasses 13 million tons, where 31% are exported and 69% supply the internal market, guaranteeing an annual consumption of 45.27 kilos of chicken meat per inhabitant. Its consumption is linked to several factors, such as being healthier, flavor, and lower price. This study aims at verifying if the selling of chicken meat in supermarkets of Recife is being practiced following the commercialization standards of current legislation. This work verified if the temperature where the meat is exposed is following the conditions presented by the legislation. We also present suggestions intended to improve the current conditions of storage, exposition, and selling of this product. It has been selected a sample of five sale points, where was collected six pieces of beef from each supermarket. It has been considered two types of cuts (chicken breast and chicken thigh). Hence, 30 meat samples in total. The samples were conditioned in polyethylene plastic bags or polystyrene boxes, simulating the same conditions the product is offered to regular customers. To evaluate the temperature conditions, a portable multi-function digital thermometer was used with a metallic rod and -50ºC to 300ºC measurement capacity, and 0,1ºC resolution. All of the five sites had visible thermometers and exposed enough pieces in the glass case. However, in one of the sites, the device presented a biased temperature. Four out of five sites had the correct number of pieces allowed to be exposed simultaneously. Regarding the temperature conditions of the chicken meat, only two sites have followed the regulations of the “regulatory standard n° 4/2014 – DIVISA/SVS/SES”. Therefore, only 13 out of the 30 samples (43%) have followed the current regulations of ideal temperature for refrigerated chicken meat. Therefore, approximately 57% of the visited places followed the regulation standards.The results allowed us to identify that especially the smaller stores face struggles to meet the regulations for accommodation and the ideal temperature of chicken meat, which impact the quality of the product for end consumers. It has been suggested the deployment of training programs to employees so that the quality and best-practices of the selling of chicken meat and its nutritional value can be kept. In consequence, improving the food safety for the clients.

The quality of the water for consume is animportant factor for the health and life quality of the consumers.The Brazilian Health Minister (MS) guarantees the harmlessness of the water consumed by the Brazilians over the establishment of rules and standards based of the presence of toxic compounds and bacteria. The search for natural mineral water is great all over the world and many are the reasons that lead the consumers to acquire this product, among them the purity characteristics contribute for this rise. Although, studies show cases of contaminations by fungus in bottled mineral water, being found even in high counting, even in anoligotrophic environment. This can constitute health risk for the consumers, mainly by immunocompromised individuals. The Brazilian legislation does not include fungus in the microbiological analysis for potable water. This work shows the presence of fungus in bottled water of 20 liters, comercialized in the great are of the city of Recife (RMR).There were randomly selected fifty 20 L bottles of tendifferent brands. From each brand there were analysed 5 samples of different lots, accordingly methodology of plate counting established in the Standard Methods for the Examination of Water and Wastewater. Contaminants fungus were found in every brand in different concentrations, with the 10 brands here identified from A to J, 8 showed contamination by filamentous fungus and yeast (A, C, D, E, F, G, H, J) and a difference in the contaminant quantity.The B and I samples showed low contamination by filamentous fungus and did not showed the presence of yeast.The pH of the analysed samples variedfrom 4.1 and 5.4. The results of this research allowed to conclude that the bottled water in 20Lbottles comercialized in the RMR can be contaminated by fungus; that there is great variation in the contaminations by this kind of microorganisms and that the pH of the different brands analysed, between 4,1 and 5,4, can contribute to the presence and/or development of the contaminants fungus. It is expected that with these records, contribute for the inclusion of fungus in the potability parameters for the human consume. Because the confrontation of these information with from others researchers, shows that this kinds of water can be animportant path to the dissemination of fungus and diseases transmissions.

For the past years, the rising consume og bottled water in Brazil is a fact that is being studied by researchers of different parts of the country. The possible reasons for the case is the fact that bottled water transmits protection to the health, studies confirm different contamination levels in this kind of water. To ensure the health of consumers, it is required a quality standard for the commercialization of this product. An example of this, ministries as the Health Minister (MS) and the National agency of Health sanitization (ANVISA) establish microbiological parameters for the bottled natural mineral water destined to human consumption. For many reasons, it is considered important the information regarding hygienic sanitary indexes presented in the bottled water. This research has the purpose to evaluate the microbiological quality of the bottled water commercialized in the Region of the great Recife (RMR) by means of microbiological analysis of the hygienic sanitary indexes. Pseudomonas aeruginosa and Coliforms. There were evaluated 9 different brands of bottled water in 20L package, coded as A, B, C, D, E, F, G, H and I. From each brand there collected 5 samples in the period between August of 2018 and June of 2019, totaling 45 samples. For the microorganisms detection, there were used validated methods by the American Public Health Association (APHA), by the American Waters Works Association (AWWA) and by the Water Environment Federation (WEF). The obtained results confirmed the presence of Pseudomonas in 64% of the samples and of Coliforms in 66% of the samples, what may led to conclude the Pseudomonas aeruginosa and Coliforms can occur in natural mineral water bottled in 20L package commercialized in the RMR; an expressive number of brands showed to be unsafe due to the presence of microorganisms indicators of the hygienic sanitary conditions; the contamination levels by the Pseudomonas aeruginosa and Coliforms, vary among different brands of bottled water and beside what was found, we can find in the RMR market, mineral water brands that are considered safe, regarding the microbiological aspects. Such results are considered concerning, since the search for bottled water is, mainly, for the apparently guaranteed safety.
