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.
Book Synopsis Effects of In-feed Additives on Performance, Gut Microbe Ecology, and Antimicrobial Susceptibility of Enterobacteria on Nursery Pigs by : Hayden Ervin Williams
Download or read book Effects of In-feed Additives on Performance, Gut Microbe Ecology, and Antimicrobial Susceptibility of Enterobacteria on Nursery Pigs written by Hayden Ervin Williams and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments using a total of 720 nursery pigs were used to determine the effects of Elarom SES, in-feed antibiotics, zinc, or copper on nursery pig growth performance and fecal consistency. Two experiments using a total of 1,534 nursery pigs were used to determine the effects of formaldehyde inclusion, lysine level, and synthetic amino acid inclusion on nursery pig performance, amino acid utilization, and gut microbial community. One experiment using a total of 300 nursery pigs were used to determine the effects of chlortetracycline (CTC) or a probiotic inclusion on nursery pig growth performance and antimicrobial susceptibility. Experiment 1 determined the effect of Elarom SES, in-feed antibiotics, or zinc on nursery pig performance and fecal consistency. The addition of Elarom SES or ZnO alone reduced ADG, but G:F was poorest when all three additives were fed in combination. Addition of in-feed antibiotics increased ADG and G:F throughout the study. Experiment 2 determined the effects of Elarom SES or copper inclusion on nursery pig performance and fecal consistency. The addition of Elarom SES or increasing copper did not provide consistent benefits in performance. In both experiments, there were no individual or overall treatment effects or treatment × day interactions observed for fecal consistency. Experiment 3 compared the effects of formaldehyde source and lysine level on nursery pig growth performance. Regardless of source or lys level, the inclusion of formaldehyde in nursery pig diets marginally reduced ADG and resulted in poorer G:F. Experiment 4 compared the effects of formaldehyde and synthetic amino acid inclusion level on nursery pig growth performance, amino acid utilization, and gut microbial community. The inclusion of Sal CURB in diets reduced ADG and ending BW while inclusion decreased ADFI. ADFI response was dependent on synthetic amino acid level in the diet. Sal CURB inclusion in diets reduced total and available lysine, but reduced bacterial microflora in treatment feed. Experiment 5 determined the effects of CTC or a probiotic on nursery pig performance and antimicrobial susceptibility. The addition of CTC to diets improved ADG, ADFI, and ending BW. The addition of Poultry Star improved ADFI and d 14 BW, but benefits did not carry throughout the study.

Download or read book Preharvest Food Safety written by Siddhartha Thakur and published by John Wiley & Sons. This book was released on 2020-07-10 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of farm-to-fork safety in the preharvest realm Foodborne outbreaks continue to take lives and harm economies, making controlling the entry of pathogens into the food supply a priority. Preharvest factors have been the cause of numerous outbreaks, including Listeria in melons, Salmonella associated with tomatoes, and Shiga toxin-producing E.coli in beef products, yet most traditional control measures and regulations occur at the postharvest stage. Preharvest Food Safety covers a broad swath of knowledge surrounding topics of safety at the preharvest and harvest stages, focusing on problems for specific food sources and food pathogens, as well as new tools and potential solutions. Led by editors Siddhartha Thakur and Kalmia Kniel, a team of expert authors provides insights into critical themes surrounding preharvest food safety, including Challenges specific to meat, seafood, dairy, egg, produce, grain, and nut production Established and emerging foodborne and agriculture-related pathogens Influences of external factors such as climate change and the growing local-foods trend Regulatory issues from both US and EU perspectives Use of pre- and probiotics, molecular tools, mathematical modeling, and one health approaches Intended to encourage the scientific community and food industry stakeholders to advance their knowledge of the developments and challenges associated with preharvest food safety, this book addresses the current state of the field and provides a diverse array of chapters focused on a variety of food commodities and microbiological hazards.
Book Synopsis Novel Pre-Harvest Approaches to Control Enteric Food-Borne Bacteria in Poultry by :
Download or read book Novel Pre-Harvest Approaches to Control Enteric Food-Borne Bacteria in Poultry written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known that two of the most common microorganisms associated with food-borne illnesses are Campylobacter jejuni and Salmonella serotypes which are readily found in poultry house environments. Poultry products have been repeatedly implicated as a significant source of food-borne disease organisms. This has researchers examining methods of reducing bacteria at the farm level. The primary focus of this study will be on novel pre-harvest methods to control food-borne bacteria in poultry. Four studies were conducted to examine the potential of using mannose or peptide-containing biofunctionalized nanoparticles (BN) to bind Campylobacter jejuni (C) in vitro or in the gastrointestinal (GI) tract of poultry. Two additional studies were conducted to examine the effects of two feed additives, Immustim® and Protimaz®, on growth performance and bacterial pathogen populations in the lower GI tract and ceca of broiler chickens. The objective of the preliminary tolerance study was to determine the effect of the BN polystyrene cores on turkey poult performance to 6wk with observation to 14wk. In this study, 198 1-wk old Nicolas turkey poults placed in 6 pens were banded, weighed and then gavaged with varying volumes (0.1, 0.5 or 1.0mL) of different polystyrene core aqueous suspensions. In all pens, 3 control poults were gavaged with distilled water. BW was determined at wk 1, 3 and 6 with observations to 14 wk. There were no significant differences (Pd".05) in BW or BW gains due to the polystyrene cores. Thus, the cores were apparently tolerated by the turkey poults and did not impact growth performance. The second study utilized an in vitro protocol to examine BN-bacterial aggregation activity. Aqueous BN suspensions were diluted 1:1, 1:10 and 1:100 in 0.1% peptone water, mixed with 1.5mL of suspended C and incubated at room temperature. The mixtures were sampled at 5 and 30 minutes, plated onto Brucella agar and incubated at 42 & deg;C for 48h. Population.
Book Synopsis Improving Food Safety Through a One Health Approach by : Institute of Medicine
Download or read book Improving Food Safety Through a One Health Approach written by Institute of Medicine and published by National Academies Press. 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.
Book Synopsis The Effect of Feeding Live Yeast and Yeast Extracts on Growth Performance and Antimicrobial Susceptibility of Fecal Escherichia Coli in Sows and Nursery Pigs by : Jenna Austin Chance
Download or read book The Effect of Feeding Live Yeast and Yeast Extracts on Growth Performance and Antimicrobial Susceptibility of Fecal Escherichia Coli in Sows and Nursery Pigs written by Jenna Austin Chance and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is comprised of 3 chapters involving studies evaluating live yeast and yeast extracts with or without the addition of pharmacological levels of Zn, feeding sows live yeast and a yeast extract and following their offspring into the nursery where progeny were fed varying inclusions of yeast additives and direct fed microbials (DFM). Chapter 1 involved 360 weanling barrows to determine the effects of feeding live yeast and yeast extracts with or without pharmacological Zn on nursery pig growth performance, fecal dry matter (DM), and antimicrobial susceptibilities of fecal E.coli. The results suggest that feeding pharmacological Zn for 21-d post-weaning is an effective strategy to optimize growth performance, economic criteria, and increase fecal DM for the first few days following weaning. Although all isolates were classified as susceptible to ciprofloxacin, the minimal inhibitory concentration (MIC) of fecal E.coli tended to be increased when pigs were fed pharmacological levels of Zn but no difference was observed to the remaining thirteen antimicrobials that were evaluated. Thus, the short-term use of pharmacological levels of Zn did not increase antimicrobial resistance (AMR). There was no benefit for any of the growth, economic, fecal DM, or AMR response criteria when live yeast and yeast extracts were included in the diets. Chapter 2 involved three batch-farrowing groups where 80 sows were used to determine the effects of feeding live yeast and a yeast extract's impact on sow and litter performance. One of the three sow groups (27 sows) were used to determine the yeast additives impact on the antimicrobial susceptibility of sow fecal E.coli. The results suggest that feeding live yeast and a yeast extract, from d 110 of gestation through lactation, may increase sow feed intake but had no impact on any other sow or litter performance criteria. A diet by sampling day interaction revealed that fecal E.coli isolates gained resistance to the antimicrobial cefoxitin over time when the yeast additives were included in the diet, but the main effect of diet had no impact on any of the fourteen antibiotics tested. Chapter 3 consisted of two experiments which used 670 weaned pigs to evaluate previous sow treatment (control vs yeast additives) and nursery diets with varying combinations of yeast additives and DFM. In Exp. 1, subsequent offspring from one of the sow groups in chapter 2 were fed either a control diet or a diet that contained live yeast and yeast extracts to evaluate growth performance and the AMR patterns of fecal E.coli. In Exp 2., subsequent offspring from one of the sow groups in chapter 2 were fed either a control diet, a diet containing yeast extracts (DFM 1), or a diet with Bacillus spp. and yeast extracts (DFM 2). Results from both studies suggest that feeding sows yeast additives from d 110 of gestation through lactation can improve growth performance of their offspring in the nursery. In Exp. 1, feeding live yeast and yeast extracts in the nursery appeared to hinder growth performance. However, in Exp. 2, pigs that were fed DFM 2 reported optimized growth in the late nursery period. In Exp 1., results suggest that progeny from sows that were fed yeast might increase the potential of fecal E.coli MIC to nalidixic acid, ciprofloxacin, and gentamicin. Yet, feeding live yeast and yeast extracts in the nursery may lower the MIC of azithromycin and chloramphenicol of fecal E.coli.

Download or read book Interventions for the Control of Non-typhoidal Salmonella Spp. in Beef and Pork written by Food and Agriculture Organization of the United Nations and published by Microbiological Risk Assessmen. This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Non-typhoidal Salmonella spp. are estimated to cause 93.8 million cases of acute gastroenteritis and 155,000 deaths globally each year, approximately 85% of which are estimated to be foodborne, establishing Salmonella as having a significant public health and economic impact on society. Pork products are among the top food-borne sources of Salmonella globally, while beef products have been implicated in several large outbreaks in recent years. Contamination of beef and pork with Salmonella can also have a negative impact on the agri-food and trade sectors due to costly recalls of products and by limiting market access. FAO and WHO have undertaken a systematic review of the available evidence on interventions to control Salmonella in beef and pork from primary production through processing. This information was then considered by an expert meeting which provided recommendations on efficacious interventions. This report presents the outcome of those deliberations as well as the review of studies on which the discussions were based, providing the reader with a wealth of up to date information on the currently available interventions for the control of Salmonella in beef and pork."--Publisher's description.
