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 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 2019-09-05 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 2022-10-14 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the 2004 risk assessment, outbreaks of illness and resultant deaths due to L. monocytogenes continue to occur across the globe. Continued effort is needed to summarize and critically evaluate the most recent information on L. monocytogenes in RTE foods. New data to improve and further inform the 2004 Risk Assessment is available for nearly every factor considered previously, including new quantitative data on L. monocytogenes contamination of foods. To facilitate this work, an FAO/WHO expert meeting was held by virtual means from 20 October to 6 November 2020 to review and discuss the available data and background documents, and to assess the need to modify and update risk assessment models/tools. This report focuses on the deliberations and conclusions of the expert meeting.

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 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 excerpt: In 2019, following a request from the Codex Committee on Food Hygiene (CCFH), the Codex Alimentarius Committee (CAC) approved new work at its 42nd Session on the development of guidelines for the control of Shiga toxin-producing Escherichia coli (STEC) in leafy vegetables and in sprouts. The objective of the report was to evaluate commodity-specific interventions used at all stages of fresh fruit and vegetable production from primary production to post-harvest activities, transportation, point of sale and consumer use. Emphasis was placed on the identification and evaluation of interventions used throughout the world to reduce microbiological hazards of fresh fruits and vegetables that contribute to the risk of foodborne illnesses, taking into consideration their effectiveness, practicality and suitability. The expert committee addressed four subdivided commodity groups: 1) leafy vegetables and herbs, 2) berries and tropical fruits, 3) melons and tree fruits, and 4) seeded and root vegetables.

This book was released on 2024-01-15 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to a request from the 52nd Session of the Codex Committee on Food Hygiene (CCFH), the FAO/WHO Joint Expert Meetings on Microbiological Risk Assessment (JEMRA) convened this meeting, to collate and assess the most recent scientific information relating to the control of non-typhoidal (NT)-Salmonella spp. in chicken meat. The assessment included a review of the Codex Guidelines for the Control of Campylobacter and Salmonella in Chicken Meat (CXG 78-2011). The Campylobacter will be reviewed by another meeting. The expert consultation noted that no single control measure was sufficiently effective in reducing either the prevalence or the level of contamination of broilers and poultry meat with NT-Salmonella spp. Instead, it was emphasized that control strategies based on multiple intervention steps would have the greatest impact on controlling NT-Salmonella spp. in the broiler production chain. 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.

Download or read book Ranking of low moisture foods in support of microbiological risk management Meeting report and systematic review written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2022-07-22 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-moisture foods (LMF) are foods that are naturally low in moisture or are produced from higher moisture foods through drying or dehydration processes. These foods typically have a long shelf life and have been perceived for many years to not represent microbiological food safety risk hazards. However, in recent years, a number of outbreaks of foodborne illnesses linked to LMF has illustrated that despite the fact that microorganisms cannot grow in these products, bacteria do have the possibility to persist for long periods of time in these matrices. Responding to a request from the Codex Committee on Food Hygiene (CCFH), the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) implemented a series of activities aimed at collating and analysing the available information on microbiological hazards related to LMF and ranking the foods of greatest concern from a microbiological food safety perspective. Seven categories of LMF which were ultimately included in the ranking process, and the output of the risk ranking, in descending order was as follows: cereals and grains; dried protein products; spices and dried herbs; nuts and nut products; confections and snacks; dried fruits and vegetables; and seeds for consumption.
