Monitoramento da Qualidade do leite: Procedimentos Diagnósticos

Means for milk, not otherwise specified, the product from complete and uninterrupted milking , in a hygienic, healthy cows, well fed and rested. The milk of other animals must be called according to origin of species. One of the main characteristics that defined the milk is the set of their sensory characteristics, and the main flavor. The control of milk quality in Brazil has been an important factor for the consolidation of the entire production chain, passing necessarily by the dairy industry. The production of milk with good quality guarantees, of course, food safety for consumers. The measures to obtain milk begin on the property, in carrying out correct procedures for milking, storage and transportation of the product also in the dairy. Later, in the laboratory evaluation of physicochemical properties, research fraud, and microbiological examinations. Finally, measures of health education are need for producers to become aware of the economic benefits by obtaining a better quality milk. The objective of this review is to emphasize the importance of using diagnostic procedures methods for the control of mastitis and consequently obtain better Milk quality

Análise da qualidade microbiológica em leite pasteurizado, tipo C, recém pasteurizado e na data de validade

The conservation of raw milk for long periods of time under refrigeration can result in the lost of its quality. This happens because bacterias, capable of developing in low temperatures, as psichrotrophics, in milk, associates with its enzymatic activities, are capable to degradate it. Although the pasteurization of milk sufficiently diminishes the transmission of the illnesses, that generally eliminates such microorganisms, is not a total efficient process because many enzymes produced for such bacterias are termostable, being able to resist the treatment and to remain active, leading to the loss of the quality of milk and its derivatives. The Normative Instruction 51 of 2002 established that milk must be cooled and stored in the production property, what resulted increasing the incidence of such bacteria in population destined milk. In some parts of the world contaminated milk is causing serious risks to the health of the population, assuming great importance in Public Health, mainly in relation to the hygienic-sanitary conditions of the product. ANVISA establishes, thus, maximum bacteriological concentration that must be evidenced before commercializing the product, guaranteeing the quality of milk as proper for consumption. Based on these aspects, the objective of this work is the microbiological analysis of 30 milk samples type C, collected in bakeries of the city Botucatu, in the state of São Paulo. Analysis were made to determinate the most likely number of termotolerants coliforms, as well the number of colony units of psichrotrophics bacterias, the presence of Salmonella and the enumeration of positive Staphylococcus aureus, at the moment of purchase and validity of the products

Impacto da Mastite nos parâmetros reprodutivos em gado de leite

This study aimed to conduct a review in most articles relating mastitis and reproduction. Mastitis affects the reproduction according to its time of occurrence and agent. Mastitis affects the interval interestrus and also increases the number of days open, the number of services per conception, the abortion rate and decreases the conception rate. The inflammatory reaction generated by mastitis and all the toxins produced by bacteria alter the entire endocrine profile of cows that experienced episodes of mastitis and thus affect their reproduction

Estudo de caso: aplicação do método DMAIC-White Belt- na redução de latas amassadas em uma produção de leite em pó

This work consists of the implementation of the steps Define, Measure , Analyze , Improve and Control ( DMAIC ) to develop a Six Sigma project in an industry the food industry. The objective was to demonstrate a potential for reducing the occurrence of crushed cans in potting milk powder industry in a White Belt project. The food industry accounts for about 9 % of Brazil's gross domestic product ( GDP ), generating thousands of jobs . Among the major sectors of the food industry is the manufacturing sector of milk , occupies approximately 10 % of the total turnover of the food industry . Brazil is considered today one of the eight largest producers of milk powder in the world. The milk powder is packed , mostly for aluminum cans that are lined internally with varnishes and other materials to protect the milk of metals from aluminum. When the cans are dented food protection is compromised and may lead ingestion causing dis-eases such as botulism. Aiming to solve the problem of dented cans methodology was used as a case study with a quantitative approach through the DMAIC method. Some quality tools used in each step of the project as brainstorming , cause and effect diagram , flowchart , ef-fort and impact matrix, 5W1H , among other Pareto diagram is presented . A survey about the disposal of cans in the company verifying a mean loss and, from this histor-ical , a goal loss was calculated was performed . With the target set we calculated the annual saving design . During application of DMAIC was found that the highest rate of loss occurred in transportation between the factory and the factory that fills cans milk . Several actions were taken to resolve problems that resulted in dented cans and the first two months of phase control it was found that the smaller losses calculated target resulting in a saving for the company. The short time of implementa-tion of the Improve phase did not allow a more detailed a ...

Medidas de adequação ambiental para indústria de leite e derivados, como requisito para gestão ambiental

The society continues demonstrating its need regarding the products and services, even though it becomes increasingly value the protection of the environment. In this context, environmental management is defined as a management method that emphasizes to continuously improve results and promote sustainable development. Moreover it has as a tool the laws which provide the benchmarks and mechanisms for companies to adapt their activities in such a way that does not alter the quality of the environment. In this sense, in order to propose improvements to a dairy aiming their environmental suitability, a present study was prepared by following the production activities of the enterprise, the raising of standards and applicable legal requirements and environmental assessment for the preparation of an array of aspects and impacts with the task of identifying the most significant according to MOREIRA (2006). The results indicated that some of the impacts of high relevance are related to the generation of wastewater and solid waste, which do not have treatment and / or proper disposal and indeed require intervention for their suitability. Through, these results were drawn up proposals for actions conformation. In addition, they were proposed meeting the requirement for health and safety at work, in accordance with the standard regulations. This study has the function, therefore, propose to the company in question, an environmental management plan that ensures the protection of the environment and health of employees and consequently the improvement of production processes and products

Staphylococcus sp na produção primária de leite: aspectos de saúde pública

Staphylococcus is one of the more important causes of the called Foodborne Disease(FD), being that from the 40 species described from genus, the more important is Staphylococcus aureus. During years believed that the S. aureus was the only specie from genus able to produce enterotoxins, responsable for the clinical frame in humans, but latest studies report the isolation of other species both positive coagulase (PC) as negative with enterotoxigenic potential. The symptoms of this intoxication appear after a short period of incubation (2-6 hours) and usually characterized by nausea, vomits, abdominal ache, diarrhea, and rarely is fatal. For the toxin to be formed in food is necessary that bacteria population to be at least 105 UFC/g, being that such toxins characterized by presenting great resistance front of gastrointestinal proteases and of homemade termical treatment. Among the main foods that might carry the microorganism, the milk and its derivatives have highlights. The contamination of the product might happen as from the milk from cows with clinical and/or subclinical mastitis, as the Staphylococcus genus is one of the main agents etiologic from this disease, equipments utensils badly sanitized equipments and utensils and from the manipulators. The control of these factors configures as fundamental condition for the achievement of a safe, quality product, which doesn’t offer risk to the consumers

Impacto de interações antrópicas sobre o comportamento de peixes-boi marinhos (Trichechus manatus manatus) reintroduzidos no litoral norte de Alagoas

Atualmente o encalhe de filhotes órfãos representa uma das principais ameaças à conservação do peixe-boi marinho (Trichechus manatus manatus) no litoral nordeste do Brasil. O Projeto Peixe-boi resgata os filhotes encalhados, reabilita em cativeiro e reintroduz estes animais em áreas de ocorrência histórica e em locais onde a população está em declínio. Estudos sobre comportamento animal fornecem uma importante ferramenta para avaliação dos Programas de Reintrodução. Os trabalhos existentes sobre comportamento de peixes-boi marinhos em vida livre sujeitos a interações antrópicas restringem-se a animais nativos na Flórida. No Brasil, há estudos etológicos apenas com espécimes em cativeiro ou recinto em ambiente natural. O objetivo do trabalho foi verificar possíveis alterações comportamentais de peixes-boi reintroduzidos, ou seja, que passaram parte da vida em cativeiro e foram soltos em ambiente natural, em função de interações antrópicas. No período de Fevereiro a Julho de 2010, com o auxílio da radio-telemetria, uma fêmea e dois machos (8 anos de idade) foram observados diariamente, em períodos alternados, com a metodologia do “animal focal”. Para o monitoramento, utilizou-se bicicleta, caiaque e, em locais de difícil acesso, o mesmo foi feito a pé. Totalizou-se 114 horas de observação para Arani e 167 horas para Potiguar. As observações da fêmea Aira ficaram comprometidas em função da perda do equipamento de radio-telemetria. A análise dos dados mostrou uma alta freqüência de comportamentos de interação (mais de 50%) em relação aos demais comportamentos de função vital para os dois machos. Dessas interações, as com animais de mesma espécie e objeto atingiram elevadas freqüências. Verificou-se ainda que a categoria afiliativa foi predominante nas interações entre peixes-bois...

Sucessão estratigráfica do Andar Alagoas na Serra do Tonã, Bacia do Tucano (BA)

STRATIGRAPHIC SUCCESSION OF ALAGOAS STAGE ON SERRA DO TONÃ, TUCANO BASIN (BAHIA). Located in northeast of Bahia, serra do Tonã is a NS elongated plateau that standsout in the flattened relief of Tucano Basin. The stratigraphic succession belongs to the Aptian post-rift sequence of this basin. Based on facies analysis, vertical stratigraphic profiles and satelite images interpretation, three stacked stratigraphic units were recognized: (1) lower carbonate unit, composed by laminated limestones and breccias, 5 m thick, correlated with Camadas Batateira of Arripe Basin; (2) intermediate siliciclastic unit, 100m thick and made of sandstones exhibiting finning upward cycles, overlaid by mudstones and sandstones wich sedimentary structures suggest action of tidal currents and (3) upper carbonate unit, composed by laminated limestones, 2-10 m thick, related with Santana Formation, that record lacustrine environment with possible marine influence. Paleocurrent analysis indicates proviniance from north and paleoflows towards south, similar to the Aptian fluvial facies of Araripe Basin, showing that both basins integrated the same continental paleodrainage
