This book was released on 2022-10-12 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although Shiga toxin-producing Escherichia coli (STEC) have been isolated from a variety of food production animals, they are most commonly associated with ruminants from which we derive meat and milk. Because of the widespread and diverse nature of ruminant-derived food production, coupled with the near ubiquity of STEC worldwide, there is no single definitive solution for controlling STEC that will work alone or in all situations. Instead, the introduction of multiple interventions applied in sequence, as a “multiple-hurdle scheme” at several points throughout the food chain (including processing, transport and handling) will be most effective. This report summarises the review and evaluation of interventions applied for the control of STEC in cattle, raw beef and raw milk and raw milk cheese manufactured from cows’ milk, and also evaluated available evidence for other small ruminants, swine and other animals. The information is presented from primary production, to the end of processing, providing the reader with information on the currently available interventions based on the latest scientific evidence. This work was undertaken to support the development of guidelines for the control of STEC in beef, raw milk and cheese produced from raw milk by the Codex Committee on Food Hygiene (CCFH).

This book was released on 2019-09-05 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shiga toxin-producing Escherichia coli (STEC) infections are a substantial public health issue worldwide, causing more than 1 million illnesses, 128 deaths and nearly 13 000 Disability-Adjusted Life Years (DALYs) annually. To appropriately target interventions to prevent STEC infections transmitted through food, it is important to determine the specific types of foods leading to these illnesses. An analysis of data from STEC foodborne outbreak investigations reported globally, and a systematic review and meta-analysis of case-control studies of sporadic STEC infections published for all dates and locations, were conducted. A total of 957 STEC outbreaks from 27 different countries were included in the analysis. Overall, outbreak data identified that 16% (95% UI, 2-17%) of outbreaks were attributed to beef, 15% (95% UI, 2-15%) to produce and 6% (95% UI, 1-6%) to dairy products. The food sources involved in 57% of all outbreaks could not be identified. The attribution proportions were calculated by WHO region and the attribution of specific food commodities varied between geographic regions. In the European and American sub-regions of the WHO, the primary sources of outbreaks were beef and produce. In contrast, produce and dairy were identified as the primary sources of STEC outbreaks in the WHO Western Pacific sub-region. The systematic search of the literature identified useable data from 21 publications of case-control studies of sporadic STEC infections. The results of the meta-analysis identified, overall, beef and meat-unspecified as significant risk factors for STEC infection. Geographic region and age of the study population contributed to significant sources of

This book was released on 2019-02-18 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shiga toxin-producing Escherichia coli (STEC) infections are a substantial health issue worldwide. Circa 2010, foodborne STEC caused > 1 million human illnesses, 128 deaths, and ~ 13,000 Disability Adjusted Life Years (DALYs). Targeting interventions appropriately relies on identifying those strains of greatest risk to human health and determining the types of foods that cause STEC infections. There are hundreds of STEC serotypes; however, based on the evidence gathered during the review, the Expert Group concluded that the serotype of the STEC strain should not be considered a virulence criterion. All STEC strains with the same serotype should not be assumed to carry the same virulence genes and to pose the same risk, as many STEC virulence genes are mobile and can be lost or transferred to other bacteria. this report proposes a set of criteria for categorizing the potential risk of severity of illness associated with a STEC in food is recommended based on evidence of virulence gene profiles and associations with clinical severity. The criteria could be applied by risk managers in a risk-based management approach to control STEC in food. While ruminants and, other land animals are considered the main reservoirs for STEC, various largescale outbreaks have been linked to other foods. Thus, the report also addresses source attribution of foodborne STEC infections globally in order to inform the development of international standards by the Codex Alimentarius on the control of STEC, and in particular identify the foods which should be the focus of those standards. Finally it provides a review of monitoring programmes and methodology for STEC which can serve as a reference for countries planning to develop such programmes.

This book was released on 2019-01-22 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Strains of pathogenic Escherichia coli that are characterized by their ability to produce Shiga toxins are referred to as Shiga toxin-producing E. coli (STEC). STEC are an important cause of foodborne disease and infections have been associated with a wide range of human clinical illnesses ranging from mild non-bloody diarrhoea to bloody diarrhoea (BD) and haemolytic uraemic syndrome (HUS) which often includes kidney failure. A high proportion of patients are hospitalized, some develop end-stage renal disease (ESRD) and some die. The information requested by CCFH is divided into three main areas: the global burden of disease and source attribution; hazard identification and characterization; and monitoring, including the status of the currently available analytical methods. This report provides an overview of the work undertaken in response to the request from the CCFH and provides the conclusions and advice of the Expert Group based on the currently available information.

This book was released on 2014-11-11 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shiga toxin-producing Escherichia coli (STEC) is an important foodborne pathogen associated with both outbreaks and sporadic cases of human disease, ranging from uncomplicated diarrhoea to haemorrhagic colitis (HC) and haemolytic uraemic syndrome (HUS). STEC affects children, elderly and immuno-compromised patients. STEC is capable of producing Shiga toxin type 1 (Stx1), type 2 (Stx2) or both, encoded by stx1 and stx2 genes, respectively. These strains are likely to produce putative accessory virulence factors such as intimin (encoded by eae), an enterohaemolysin (EhxA) and an autoagglutinating protein commonly associated with eae-negative strains (Saa), both encoded by an enterohaemorrhagic plasmid. Several studies have confirmed that cattle are the principal reservoir of STEC (O157 and non-O157:H7 serotypes) and many of these serotypes have been involved in HUS and HC outbreaks in other countries. Transmission of STEC to humans occurs through the consumption of undercooked meat, vegetables and water contaminated by faeces of carriers and by person-to-person contact. Diagnostic methods have evolved to avoid selective diagnostics, currently using molecular techniques for typing and subtyping of strains. Control is still a challenge, although there are animal vaccines directed against the serotype O157:H7.
Book Synopsis Shiga Toxin-producing Escherichia Coli (STEC) by : Delphine Larose
Download or read book Shiga Toxin-producing Escherichia Coli (STEC) written by Delphine Larose and published by . This book was released on 2016 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enterohemorrhagic E. coli (EHEC) are responsible for important diseases such as hemorrhagic colitis,hemolytic and uremic syndrome or thrombotic thrombocytopenic purpura. Human infections occurprincipally by consumption of contaminated food particularly beef meat, milk or vegetables. The mainnaturally reservoir of EHEC is the gastro-intestinal tract of cattle. Cattle feces are therefore responsiblefor contamination of various types of food but also environment dissemination of the pathogenicbacteria. Related to this problematic, the two objectives of this project were (i) to develop a newimmuno-capture method to improve the isolation of the main serogroups of EHEC involved in humaninfections in food; and (ii) to develop a new direct fed microbial usable in cattle to decrease prevalenceof EHEC in animals. This thesis allowed the development of an immuno-capture method based on theuse of 96-well microplates coated with specific antibody directed against E. coli O157 and otherserogroups. This method, called immuno-microplate capture (IMC) was efficient and user-friendly forthe isolation of E. coli O157; O26; O103 and O111 in foods. This could be an alternative to the use ofimmuno-magnetic beads which are currently used for the detection of EHEC in foods, but are timeconsumingand labor intensive when large number of samples is analyzed simultaneously. The secondpart of this thesis allowed the selection of 5 lactic acid bacteria strains which presented highantagonistic activity against E. coli O157 and other serogroups in vitro. Resistance of these strains togastro-intestinal conditions (acidic conditions, presence of bile salts and rumen fluid) was evaluated invitro. The safety of the 5 strains was checked in Balb-C mice by administration of each strain mixed infeed at 109 cfu/g. Finally, freeze-drying did not affect the antagonistic activity of the 5 strains, suggesteda possible large scale use of these strains. According to the various results obtained in vitro, the 5 strainscould potentially be used as DFM in cattle to decrease colonization of their gastro-intestinal tract byEHEC and consequently decrease the risk of food and environment contaminations.

Book excerpt: To collate and assess the most recent scientific information relevant to the control of thermotolerant Campylobacter species in broiler production and chicken meat, the Joint FAO/WHO Expert Meeting on Microbiological Risk Assessment (JEMRA) convened a meeting in Rome, Italy in February 2023. The expert committee reviewed the available data on Campylobacter control including scientific literature published from 2008 to October 2022 and data submitted in response to a call for data for this meeting. The experts: 1) determined the quality and quantity of evidence of control measures for Campylobacter, 2) evaluated the impact of measures to control Campylobacter in the broiler production chain, 3) determined which hazard-based interventions pertained specifically to Campylobacter and which were general to the control of foodborne pathogens in the pre- and post-harvest broiler production chain, and 4) reviewed and recommended revisions to the Guidelines for the Control of Campylobacter and Salmonella in Chicken Meat. This report describes the output of this expert meeting and the advice herein is useful for both risk assessors and risk managers, at national and international levels and those in the food industry working to control the hazard in poultry.

This book was released on 2012-09-10 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globalization of the food supply has created conditions favorable for the emergence, reemergence, and spread of food-borne pathogens-compounding the challenge of anticipating, detecting, and effectively responding to food-borne threats to health. In the United States, food-borne agents affect 1 out of 6 individuals and cause approximately 48 million illnesses, 128,000 hospitalizations, and 3,000 deaths each year. This figure likely represents just the tip of the iceberg, because it fails to account for the broad array of food-borne illnesses or for their wide-ranging repercussions for consumers, government, and the food industry-both domestically and internationally. A One Health approach to food safety may hold the promise of harnessing and integrating the expertise and resources from across the spectrum of multiple health domains including the human and veterinary medical and plant pathology communities with those of the wildlife and aquatic health and ecology communities. The IOM's Forum on Microbial Threats hosted a public workshop on December 13 and 14, 2011 that examined issues critical to the protection of the nation's food supply. The workshop explored existing knowledge and unanswered questions on the nature and extent of food-borne threats to health. Participants discussed the globalization of the U.S. food supply and the burden of illness associated with foodborne threats to health; considered the spectrum of food-borne threats as well as illustrative case studies; reviewed existing research, policies, and practices to prevent and mitigate foodborne threats; and, identified opportunities to reduce future threats to the nation's food supply through the use of a "One Health" approach to food safety. Improving Food Safety Through a One Health Approach: Workshop Summary covers the events of the workshop and explains the recommendations for future related workshops.

Meeting report written by World Health Organization and published by World Health Organization. This book was released on 2024-01-10 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fruits and vegetables are an important part of a healthy diet and are protective against many chronic health conditions. Yet, fresh fruits and vegetables have been consistently implicated in food safety incidents involving microbiological hazards around the globe for decades. In response to requests of the Codex Committee on Food Hygiene concerning microbiological hazards in fresh fruits and vegetables and to update and expand the information available in Microbiological hazards in fresh leafy vegetables and herbs (MRA14), which was published in 2008, FAO and WHO convened a series of expert meetings in 2021 to 2022. The purpose of the meetings was to collect, review and discuss relevant measures to control microbiological hazards from primary production to point of sale in fresh, ready-to-eat (RTE) and minimally processed fruits and vegetables, including leafy vegetables. The experts made an effort to update and include any recent trends in commodity and pathogen pairing or pathogen occurrence and presence with a focus on emerging and neglected pathogens. The primary production in open fields was investigated by considering the location, adjacent land use, topography, and climate; prior land use; water; wildlife, animal and human intrusion; soil amendments; and harvest and packing. The experts also worked on: primary production in protected facilities; minimal processing; transport, distribution, and point of sale; and also the gaps in mitigation and interventions measures. The advice herein is useful for both risk assessors and risk managers, at national and international levels and those in the food industry working to control the relevant hazards in the fresh fruits and vegetables. the development of improved mitigation and intervention measures.

Book Synopsis Safety and quality of water use and reuse in the production and processing of dairy products by : Food and Agriculture Organization of the United Nations
Download or read book Safety and quality of water use and reuse in the production and processing of dairy products written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2023-02-10 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is used for a wide range of activities in the dairy sector, which consumes a substantial volume of first-use drinking water for production processes, cleaning and disinfection. There is a great potential to exploit possible sources of reusable water in the dairy sector. In 2020, the 43rd session of the Codex Alimentarius Commission approved the new work entitled ¡°Development of Guidelines for the Safe Use and Reuse of Water in Food Production¡± proposed by the 51st session of the Codex Committee on Food Hygiene. To support this work, the Joint FAO/WHO Expert Meeting on Microbiological Risk Assessment (JEMRA) was asked to provide scientific advice regarding safe use and reuse of water in the dairy sector. JEMRA convened an online meeting from 14 June to 2 July 2021 to provide clear and practical guidance on risk-based approaches to assess and manage fit-for-purpose water sourcing, use and reuse in the dairy sector. This report describes the output of this meeting to support the decision-making when applying the concept of fit-for-purpose water for use in the production and processing of dairy products.
