This paper aims to examine the issue raised by the consumption of locally produced food in all its various aspects, and in particular, addresses how this practice contributes to local and global sustainability. It analyzes the different definitions of local food, the strategies used, the implications of the distance traveled in the transportation of food to the consumer's table -food miles, the relationships between local food consumption and sustainability, farming practices that reduce carbon emissions, contribution of urban agriculture to local food, local trading of food produced by rural farmers, as well as a number of relationships between the consumption of local food and human nutrition and health, local food protection and the ability to support local food production for humanitarian actions in disaster situations. The promotion of "local food" is a complex problem covering environmental issues, the economy and health.Transportation is not the only factor that determines how efficient it is to consume local food. Often, the technologies used for agricultural production are those most responsible for the degree of sustainability in the production and supply of food to the population. Local production does not always mean lower emissions of greenhouse gases. In general, the consumption of local foods, produced in ways adapted to the local environment using technologies with an ecological basis, is something beneficial and salutary for the environment, economy and society in general.

Avaliar a qualidade da farinha obtida de grãos de trigo fumigados com atmosfera sintética (21% de CO2) associada a níveis reduzidos de fosfina (0,25, 0,50 e 0,75 g m-3) foi o que se objetivou através deste trabalho. Para posterior comparação dos resultados, realizaram-se dois tratamentos com ar ambiente associado às dosagens de zero e 1,0 g m-3 PH3, em três períodos de exposição (24, 72 e 120 h) e temperatura de 29 ºC e 60% de umidade relativa. A análise dos resultados permitiu concluir-se que, em geral, os tratamentos não influenciaram na qualidade da farinha para panificação obtida do trigo fumigado com fosfina associada à atmosfera sintética (21% de CO2) e ao ar ambiente.

RESUMOAtravés deste trabalho objetivou-se avaliar a vida pós-colheita de mamão, estudando-se o efeito da atmosfera modificada e absorvedor de etileno na qualidade dos frutos em três diferentes formas de armazenamento: frutos com embalagem de polietileno de baixa densidade (PEBD) e com absorvedor de etileno (CECA), frutos com embalagem de PEBD e sem absorvedor de etileno (CESA) e controle com frutos sem embalagem de PEBD e sem absorvedor de etileno (SE). Durante o período de armazenamento e a cada três dias, realizaram-se as seguintes análises: sólidos solúveis totais (SST), acidez titulável (AT), a razão entre SST e AT, firmeza da polpa (F) e análise sensorial, na qual foi avaliada a aceitação do produto para os atributos aroma, sabor, textura, cor da polpa e aparência. Os resultados obtidos mostraram, quanto à aceitabilidade, que os tratamentos diferiram entre si e também ao longo do período de armazenamento; para se armazenar mamões da cultivar Golden, a temperatura ambiente, é importante à utilização de embalagem de PEBD associada ao absorvedor de etileno, cujo efeito favoreceu a obtenção de frutos de qualidade, mantendo suas características físicas, químicas e sensoriais.Palavras-chave: absorvedor de etileno, filme de PEBD, qualidade, análise sensorial Postharvest characterization of stored papaya in modified atmosphere ABSTRACTThis work aimed to evaluate the postharvest quality of papaya, studyng the effects of modified atmosphere and of ethylene absorbers on fruit quality with three different modes of storage: fruits covered with film of PEBD and ethylene absorbers (CECA), fruits covered with film of PEBD without addition of ethylene absorbers (CESA) and, the control without film of PEBD and without addition of ethylene absorbers (SE). The following analyses were accomplished every 3 days during storage period: total soluble solid (TSS), titratable acidity (TA), the ratio between TSS and TA, pulp firmness and sensory analysis to evaluate the product approval according to attributes like aroma, taste, texture, color pulp and aspect. The obtained results showed differences in treatments as well as along the storage period. It was also noticed that storing papaya of the Golden cultivar in the ambient temperature, the use of packing associated with PEBD and ethylene absorbers is important because the associated effect favored the production of fruits with high quality, maintaining the physical, chemical and sensorial characteristics.

Neste trabalho, foi estudado o efeito da temperatura de armazenagem na conservação de mamão minimamente processado. Os mamões, previamente resfriados à temperatura de 6 ºC, foram submetidos à seleção, lavagem, sanitização, corte em cubos, enxágüe, e acondicionamento em embalagens plásticas de polietileno de baixa densidade rígido e armazenados em câmaras frias nas temperaturas de 5 e 10 ºC por 8 dias. Avaliou-se pH, acidez titulável, sólidos solúveis totais, vitamina C e contaminações microbiológicas no mamão minimamente processado. O delineamento experimental utilizado foi o inteiramente casualizado, com três repetições. A acidez titulável foi menor com a maior temperatura. As análise de vitamina C e pH não apresentaram diferença significativa entre as temperaturas de armazenamento. Os teores de sólidos solúveis não variaram entre os tratamentos, e os cuidados higiênicos adotados durante o processamento permitiram a obtenção de produtos com baixa contagem microbiana, no produto armazenado a 5 °C após 8 dias. Estes resultados permitem indicar o mamão para a produção de produtos minimamente processados, na forma de pedaços, com conservação a 5 oC por um período de 8 dias.

Este trabalho teve por objetivo avaliar o efeito da atmosfera modificada (100% CO2) associada a doses de fosfina no controle de Sitophilus zeamais (Motschulsky). Concluiu-se que: o aumento do período de exposição resultou no aumento da eficácia dos tratamentos; as pupas de S. zeamais foram mais tolerantes aos tratamentos, enquanto os ovos e as larvas de primeiro ínstar foram mais sensíveis e que a concentração de 0,75 g m-3 de fosfina, associada à atmosfera contendo 100% de CO2, no período de 120 h de exposição, é a mínima necessária para o controle efetivo de todas as fases de desenvolvimento do S. zeamais.

This review aims to examine the issue rural workers' health and the use of pesticides in its various aspects, especially emphasizing how that is doing in developing and developed countries. We found than the rural workers pesticide contamination problems occur both in developing countries as in developed countries. We concluded than to ensure the rural workers' health when they use pesticides becomes necessary to increase the training of workers. It is also important to build political agendas and actions in the health of agricultural workers, with implementation of preventive health programs with greater oversight and monitoring on pesticide use. IntroductionThe indiscriminate application of pesticides affects both human health and natural ecosystems. The use of pesticides in agriculture can be justified by the need to increase agricultural production, but behind the use of these substances are the risks of occupational diseases confirmed by studies that focus primarily on specific types of substances (SILVA & SADI, 2006). The epidemiology of the use of pesticides in agriculture should be seen not only in terms of consumers, but in view of occupational hazard among farmers or rural workers. DOI: 10.19180/1809DOI: 10.19180/ -2667 In general, there is a false thought that in the developed countries there is no problem related to poisoning of farm workers by pesticides. According to the "Centers for Disease Artigo de RevisãoControl and Prevention" of the United States, agriculture is the most dangerous industry for American workers, affecting mainly the younger ones. It was found that 76% of agricultural workers suffered fatal accident were under 16 years and worked in an agricultural family business that was exempt from child labor laws (CENTERS FOR DISEASE CONTROL AND PREVENTION. NIOSH, 2003).Pesticides have been widely used to control pests and diseases related to agriculture, fisheries, forestry and food industry. Throughout history it was necessary to create laws that establish safety rules regarding the use of pesticides in order to reduce their impact on the environment and the health of farm workers. Leaflet and label are examples of this and are the main sources of information for rural workers, helping to prevent accidents and consequently poisoning (ZAMBRONE & CORREA, 2008).This review aims to examine the issue rural workers' health and the use of pesticides in its various aspects, especially emphasizing how that is doing in developing and developed countries. MetodologyWe utilized the site periodic capes (www.periodicos.capes.gov.br) and the key words utilized were: "segurança and agrotóxico" and "rural work and pesticide". The time was the last 10 years. We found 75 citations and selected 35 than talked about rural workers` health related to the use of pesticides. These 35 citations, 14 were in Portuguese language: 11 papers, 1 dissertation, 1 book and 1 technical bulletin and 21 were in English language: 18 papers, 2 books and 1 technical bulletin. We found mainly citations of the last five years (...
