Selected AbstractsGlobal Standards, Local Realities: Private Agrifood Governance and the Restructuring of the Kenyan Horticulture IndustryECONOMIC GEOGRAPHY, Issue 2 2010Stefan Ouma abstract Over the past decade, private food safety and quality standards have become focal points in the supply chain management of large retailers, reshaping governance patterns in global agrifood chains. In this article, I analyze the relationship between private collective standards and the governance of agrifood markets, using the EUREPGAP/GLOBALGAP standard as a vantage point. I discuss the impact of this standard on the organization of supply chains of fresh vegetables in the Kenyan horticulture industry, focusing on the supply chain relationships and practices among exporters and smallholder farmers. In so doing, I seek to highlight the often-contested nature of the implementation of standards in social fields that are marked by different and distributed principles of evaluating quality, production processes, and legitimate actions in the marketplace. I also reconstruct the challenges and opportunities that exporters and farmers are facing with regard to the implementation of and compliance with standards. Finally, I elaborate on the scope for action that producers and policymakers have under these structures to retain sectoral competitiveness in a global economy of qualities. [source] ISTANBUL'S BOSTANS: A MILLENNIUM OF MARKET GARDENS,GEOGRAPHICAL REVIEW, Issue 3 2004PAUL J. KALDJIAN ABSTRACT. For centuries, a network of market gardens throughout Istanbul provisioned the city with fresh vegetables. These bostans and their gardeners held a respected place in Istanbul life, contributing to the city's food and employment needs. Today, only fragments remain. Massive urban development, intense competition for metropolitan space, modernization, changing institutions and laws, and the global industrialization of food have threatened this tradition with extinction. But in spite of the overwhelming forces behind their demise, some of Istanbul's bostans persist. Efforts to support and promote the gardens, and to draw from the expertise and experience of their gardeners, are emerging. From a historical perspective, this article examines Istanbul's bostans to understand their meaning and contribution to the city's people and landscape.

[source] Etiology and prevention of gastric cancer: a population study in a high risk area of ChinaJOURNAL OF DIGESTIVE DISEASES, Issue 4 2005Wei Cheng YOU A series of studies has been carried out in Linqu County, Shandong Province, China, a high-risk area for gastric cancer, to investigate the risk factors associated with gastric cancer, precancerous lesions and the prevention of gastric cancer. Our studies showed that sour pancakes (a popular local food), salted foods, cigarette smoking, and family history of gastric cancer were risk factors, whereas fresh vegetables, and intake of vitamin C and calcium were inversely associated with the risk of gastric cancer. The prevalence of chronic atrophic gastritis was approximately 20% in an adult population in Linqu County, intestinal metaplasia was approximately 50%, and dysplasia was approximately 20%. A follow-up study showed that the relative risk of developing gastric cancer increased with the severity of gastric lesions, and was associated with dietary factors, cigarette smoking and H. pylori infection in this population. The findings strongly support the idea that gastric cancer is primarily determined by environmental factors and develops in a multistep progression of precancerous lesions. [source] PREVALENCE AND ANTIMICROBIAL RESISTANCE OF LISTERIA SPECIES IN FOOD PRODUCTS IN BANGKOK, THAILANDJOURNAL OF FOOD SAFETY, Issue 1 2010SIRIPORN STONSAOVAPAK ABSTRACT A total of 380 meat and meat products, dairy and dairy products, fresh vegetables, fresh seafood, and ready-to-eat food samples from supermarkets in Bangkok, Thailand were collected and analyzed for the occurrence of Listeria spp. and of Listeria monocytogenes. The overall incidence of Listeria spp. was 16.8%, most of them were isolated from raw meat and vegetables. L. monocytogenes was isolated from 18 (4.7%) out of 380 studied samples. Other species isolated were L. innocua (6.6%), L. ivanovii (0.8%), L. seeligeri (0.5%), L. grayi (1.6%) and L. welshimeri (2.6%). The antimicrobial susceptibilities of the 64 isolate of Listeria spp. were also examined by the standard disk diffusion method. Listeria spp. were resistant to penicillin (6.3%), chloramphenicol (3.1%) and tetracycline (1.6%), but sensitive to amoxicillin, vancomycin, ampicillin, rifampicin and sulfamethoxazole. PRACTICAL APPLICATIONS Listeria monocytogenes prevalence in food products in Bangkok has been documented. More studies on the occurrence of L. monocytogenes are needed to establish microbiological criteria of foods in the country. The findings of our study, increases in antibiotic resistance among Listeria spp. will provide useful information for the development of public health policy in the use of antimicrobials in food animal production. [source] US,Mexico fresh vegetable trade: the effects of trade liberalization and economic growthAGRICULTURAL ECONOMICS, Issue 1 2001Jaime E. Málaga NAFTA; Vegetables; Trade liberalization; Mexico Abstract Studies of US-Mexico vegetable trade have generally emphasized the importance of US tariffs in determining the competitive advantage of US producers. Even so, research has identified at least four factors related primarily to the different levels of economic development in the US and Mexico that also have important effects on US-Mexico agricultural trade in general and fresh vegetable trade in particular. These include the differential growth rates of US and Mexican real wages, production technology (yields), and per capita income as well as cyclical movements in the real Mexican Peso/US Dollar exchange rate. This study examines the relative contribution of NAFTA and the development-related factors to likely future changes in US fresh vegetable imports from Mexico. The analysis employs an econometric simulation model of US and Mexican markets for five fresh vegetables (tomatoes, cucumbers, squash, bell peppers, and onions) accounting for 80% of US fresh vegetable imports. The results suggest that the 1994,1995 Peso devaluation rather than NAFTA was primarily responsible for the sharp increase in US imports of Mexican vegetables observed in the first years following the implementation of NAFTA. Over time, however, the results suggest that differences in the growth rates of US and Mexican production yields and, to a lesser extent, of US and Mexican real incomes and/or real wage rates could plausibly contribute more to the future growth of US tomato, squash, and onion imports from Mexico than the trade liberalizing effects of NAFTA. [source] Sulfur fertilization and light exposure during storage are critical determinants of the nutritional value of ready-to-eat friariello campano (Brassica rapa L. subsp. sylvestris)JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 13 2009Giancarlo Barbieri Abstract BACKGROUND: The nutritional value of fresh vegetables can be affected at different steps within the field-to-market pipeline. Both pre- and post-harvest factors should be considered in order to increase the produce quality and to preserve it until final consumption. In this study the effects of sulfur nutrition during plant growth and light exposure during storage on the nutritional value of ready-to-eat friariello campano (Brassica rapa L. subsp. sylvestris L. Janch. var. esculenta Hort.) were studied. RESULTS: Fresh weight loss was higher in light-storage treatment. During storage, light exposure reduced leaf nitrate content, although no effect could be attributed to sulfur nutrition. Sulfur increased both lipophilic and hydrophilic antioxidant activity. The hydrophilic antioxidant activity linearly decreased during storage, whereas the lipophilic activity increased over time. However, no differences could be attributed to light exposure during storage for this parameter. Results on colorimetric indexes and their relation with the chlorophyll content are also reported. CONCLUSIONS: Ready-to-eat friariello quality may be improved with an enhanced antioxidant activity and reduced nitrate content by combining, respectively, increased sulfur availability during plant growth and exposure to light during storage. On the other hand, light exposure caused a more rapid decline in produce fresh weight during storage. Copyright © 2009 Society of Chemical Industry [source] Soy, isoflavones, and prostate cancerMOLECULAR NUTRITION & FOOD RESEARCH (FORMERLY NAHRUNG/FOOD), Issue 2 2009Le Jian Abstract Prostate cancer has marked geographic variations between countries. Genetic, epigenetic, and environmental factors co-contribute to the development of the cancer. The association between dietary factors and prostate cancer has been investigated and one explanation for the low incidence of the cancer in Asia might be high consumption of fresh vegetables including soybean and its products. Soybean is a species of legume contain high amount of isoflavones including genistein, daidzein, glycitein, and equol, which have a prophylactic effect on prostate cancer. In this article, epidemiological and laboratory studies on the relationship between soybeans, isoflavones and prostate cancer are reviewed and large scale multiethnic epidemiological studies are recommended. [source] Application to routine analysis of a method to determine multiclass pesticide residues in fresh vegetables by gas chromatography/tandem mass spectrometryRAPID COMMUNICATIONS IN MASS SPECTROMETRY, Issue 11 2002J. L. Martínez Vidal The use of gas chromatography/tandem mass spectrometry (GC/MS/MS) applied to determine multiple pesticide residues in fresh vegetables has been thoroughly studied. A single injection method to detect, confirm and quantify 54 multiclass pesticides has been developed and applied in a routine analysis laboratory. The proposed method consists of a rapid extraction of 15,g of vegetable sample with dichloromethane. An additional clean-up step is not necessary even when injecting 10,µL of extract. Instead the gas chromatograph was fitted with a carbofrit inserted into the glass liner and a guard column. In addition, the detection mode chosen (MS/MS) provides additional selectivity. The method has been validated and applied to 1300 samples in a routine laboratory following specified quality criteria. The recovery efficiencies obtained for all the pesticides ranged between 70.2 and 110.8% at two different fortification levels. The relative standard deviation for quantification (RSD) was lower than 16.7% for all the compounds. Important experimental parameters, such as the conditioning of carbofrit, overload of the analytical column, and cleanliness of the ion trap, were evaluated for their influence on the performance of the method.
