| After a general presentation of the Thau lagoon together with its geographic location, socio-economic activities linked to shellfish culture and fishing, this paper investigates the health conditions of the shellfish harvesting areas. I he influence of heavy rainfall following a prolonged drought period is underlined as a determining factor of the momentary bacterial pollution in the harvesting areas, leading to a suspension of sales based on analyses relying solely on the detection of faecal coliforms. As of 1989, bacteriological monitoring was reorganized in the form of a data collection network taking into consideration environmental assessments of water quality as well as shellfish hygiene in order to protect consumer health. Its extension to the... |

| The release of enteric pathogenic bacteria in aquatic environments poses the problem of the fate of these bacteria under the effects of environmental factors (solar radiation, salt concentration, temperature, nutrient level, pH, competition). Frequently, these bacterial cells, potentially pathogenic, enter into a non-culturable state on routine bacteriological plating media. However, the use of direct detection methods (DAPI stained cells) allows the visualization of these Viable but Non Culturable cells (VNC). But, beyond the characterization of the viability of the cells (electron transport activity, metabolic activity, membrane integrity, structure and/or quantity of DNA), what happens with the virulence of these cells? This problem was experimentally... |

| During a 2-year study, the presence of human pathogenic bacteria and noroviruses was investigated in shellfish, seawater and/or surface sediments collected from three French coastal shellfish-harvesting areas as well as in freshwaters from the corresponding upstream catchments. Bacteria isolated from these samples were further analyzed. Escherichia coli isolates classified into the phylogenetic groups B2, or D and enterococci from Enterococcus faecalis and E. faecium species were tested for the presence of virulence genes and for antimicrobial susceptibility. Salmonella members were serotyped and the most abundant serovars (Typhimurium and its monophasic variants and Mbandaka) were genetically characterized by high discriminative subtyping methods.... |

| Propolis shows biological properties such as antibacterial action. This bee product has a complex chemical composition, which depends on the local flora where it is produced. Salmonella serovars are responsible for human diseases that range from localized gastroenteritis to systemic infections. The aim of the present study was to investigate the susceptibility of Salmonella strains, isolated from food and infectious processes, to the antibacterial action of Brazilian and Bulgarian propolis, as well as to determine the behavior of these bacteria, according to the incubation period, in medium plus propolis. Dilution of ethanolic extract of propolis in agar was the used method. Brazilian and Bulgarian propolis showed an antibacterial action against all... |

| Propolis antibiotic action has been widely investigated. This assay was carried out in order to observe the in vitro antibacterial activity of propolis against Salmonella enteritidis isolated from food and Salmonella typhimurium isolated from human infections. Propolis was collected by Apis mellifera in two regions of Brazil (Mossoró, Rio Grande do Norte State; and Urubici, Santa Catarina State). Both strains survival percentage decreased with time of incubation in Ethanolic Extracts of Propolis (EEP), demonstrating bactericidal effect after 24 hours. It was also observed that EEP from Mossoró was more effective than that from Urubici. The control of the propolis solvent - 70% ethanol - was less effective than EEP, showing only a bacteriostatic effect. We... |

| Thailand is a developing nation dependent on agriculture. Due to lack of modern public health practices, she suffers from the consequences of foodborne illnesses. The number of foodborne infection cases has nearly doubled in the past 10 years. Salmonella and Campylobacter pose the greatest risk of bacterial contaminants, mostly from pigs and chickens, and this paper will review livestock production systems and foodborne diseases from cases stemming from these sources. Due to the complexity of the livestock production systems, collection of data to date has been sporadic, but it is clear that controls are needed in slaughterhouse processing methods, and more communication between agencies and surrounding regions is paramount for proper surveillance to have... |

| Salmonellosis, a common human intestinal disorder primarily caused by contaminated meats and poultry, attacks an estimated two million Americans annually. Using a cost of illness approach, the medical costs and productivity losses alone were estimated to cost around one billion dollars in 1987. If pain and suffering, lost leisure time, and chronic disease costs could be quantified, the estimate would increase significantly. Other procedures for calculating the value of life could either raise or lower the estimated economic benefits of reducing human salmonellosis. Incorporating losses to farmers, whose animals have reduced feed efficiency, reduced weight gain, or deaths because of chronic salmonellosis, would also increase the estimates. Also excluded... |

| Food safety risks and microbial outbreaks have significant health impacts on society as a whole, as well as economic loss to food processing firms. According to the U.S. Centers for Disease Control (CDC), an estimated 76 million foodborne illnesses occur each year in the United States. Of these cases, 325,000 hospitalizations and 5,000 deaths occur each year (Mead et al., 1999). The U.S. Department of Agriculture, Food Safety and Inspection Services (USDA-FSIS) (1996) estimated that approximately 4,000 deaths each year are attributed to contamination in meat and poultry products. For food processing firms, microbial outbreaks often result in significant economic losses: food recalls, lost market share, and decreased consumer confidence. The intangible... |

| Food safety regulations and the perception of risk are different among countries. This can lead to persistent trade frictions and even reduce food trade. These differences may also lead to increased dialogue between countries, with improved food safety systems the result. Although little disruption to trade has occurred for food safety reasons (considering the total volume of food trade), trade issues or crises related to food safety are wide ranging. These issues and crises challenge policymakers and industries to both protect domestic food supplies and nurture international markets. Meanwhile, consumers in developed countries are demanding safer food. Risk reduction measures and quality certification programs can not only pre-empt food safety crises,... |

| This paper examines the cross-impacts of food safety news concerning one product on the demand for another product, using the Danish demand for pasteurized eggs versus shell eggs as an illustrative case. The study identifies news with a temporary impact and news with a permanent impact on consumers' food demand behavior. The techniques used to identify the permanent versus temporary news are recursive estimation and parameter stability. Whereas "permanent" news is identified to be represented by a specific individual event, "temporary" news concerning salmonella in eggs is aggregated into a news-index variable. Both temporary and permanent news concerning salmonella in shell eggs appear to have significant positive impacts on the demand for pasteurized... |

| Salmonella is widespread in nature and can be found in all links of the poultry production chain. Due to its high impact on meat processing, techniques for the rapid detection and reproducible characterization of Salmonella serotypes in foods are needed. The present study investigated the potential of molecular profiling to identify and differentiate 15 Salmonella serotypes isolated from the poultry production chain, based on 5 primers by random amplified polymorphic DNA (RAPD), enterobacterial repetitive intergenic consensus (ERIC-PCR), amplification of rDNA internal spacer analysis (RISA), and amplified ribosomal DNA restriction analysis (ARDRA) of 16S-23S rRNA internal spacer region (ISR) cleaved with Alu I and Hha I restriction enzymes. Three isolates... |

| Reducing Salmonella contamination in poultry is of major importance to prevent the introduction of this microorganism into the food chain. Salmonellae may spread during storage time (shelf life) whenever pre-harvest control fails or post-harvest contamination occurs. Therefore, preventive measures should also be used in the post-harvest level of poultry production in order to control salmonellae. Chicken skin samples were experimentally contaminated by immersing whole legs (thighs and drumsticks) in a suspension containing 10(6) colony forming units per milliliter (CFU/mL) of Salmonella Enteritidis phage type 4 (SE PT4) at the slaughter day. One day later, samples from one group were immersed in a suspension pool containing 10(9) CFU/mL of each of three... |
