Download or read book Develop Methods To Evaluate the Performance of Aflatoxin Sampling Plans for Shelled Corn written by and published by . This book was released on 1912 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Eighteen lots of shelled corn were tested for aflatoxin contamination. The variability and distributional characteristics associated with the aflatoxin testing procedure were investigated. The total variance associated with testing shelled corn was estimated and partitioned into sampling, sample preparation, and analytical variances. All variances were found to increase with an increase in aflatoxin concentration. Using regression analysis, mathematical expressions were developed to model the relationship between aflatoxin concentration and the total, sampling, sample preparation, and analytical variances. The expressions for these relationships were used to estimate the variance for any sample size, subsample size, and number of analyses for a specific aflatoxin concentration. For example, testing a lot with 20 parts per billion (ppb) aflatoxin using a 2.5 lb sample, Romer mill and 50 g subsample, and HPLC analysis, the total, sampling, sample preparation, and analytical variances are 274.9 (CV=82.9%), 214.0 (CV=73.1%), 56.3 (CV=37.5%), and 4.6 (CV=10.7%), respectively. The percentage of the total variance for sampling, sample preparation, and analytical is 77.8, 20.5, and 1.7 %, respectively. Next, fifteen positively skewed distributions were each fitted to 18 empirical distributions of aflatoxin test results for shelled corn. The compound gamma distribution was selected to model the sample aflatoxin test results for shelled corn. The method of moments technique was chosen to estimate the parameters of the compound gamma distribution. Mathematical expressions were developed to calculate the parameters of the compound gamma distribution for any lot aflatoxin concentration and test procedure. Observed acceptance probabilities were compared to operating characteristic curves predicted from the compound gamma distribution and all 18 distributions of sample aflatoxin test results were found to lie within a 95% confidence band. Using the mean and variance relationships.

Download or read book Joint FAO WHO Expert Consultation on Risk Assessment of Microbiological Hazards in Foods FAO Headquarters Rome 17 21 July 2000 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2000 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microbiological safety of food is becoming an increasingly important issue in many countries. A number of factors have contributed to this, including changes in methods of food production and processing, changing consumption patterns, greater consumer awareness of food safety issues and emerging and re-emerging pathogens. Also, the expansion of international trade in food has increased the risk of infectious agents being disseminated from the original point of production to locations thousands of miles away. In addressing this issue at the international level FAO and WHO convened a joint Expert Consultation on Risk Assessment of Microbiological Hazards in Foods from 17 to 21 July 2000 in Rome. The meeting specifically addressed risk assessment of Salmonella spp. in broilers and eggs and Listeria monocytogenes in ready-to-eat foods. This report summarizes its findings and includes advice and guidance on hazard characterization and exposure assessment of these pathogen-commodity combinations for consideration by FAO/WHO Member Countries and the Codex Alimentarius Commission.

Book excerpt: This paper provides an extensive review of different aspects of five shellfish-poisoning syndromes (paralytic, diarrhoeic, amnesic, neurologic and azapiracid), as well as one fish-poisoning syndrome (ciguatera fish poisoning), and discusses in detail the causative toxins produced by marine organisms, chemical structures and analytical methods of the toxins, habitat and occurrence of the toxin-producing organisms, case studies and existing regulations. Based on this analysis, risk assessments are carried out for each of the toxins, and recommendations are elaborated to improve the management of these risks in order to reduce the harmful effect of these toxins on public health.

Available in PDF, EPUB and Kindle. Book excerpt: This book is divided into three sections. The section called Aflatoxin Contamination discusses the importance that this subject has for a country like the case of China and mentions examples that illustrate the ubiquity of aflatoxins in various commodities The section Measurement and Analysis, describes the concept of measurement and analysis of aflatoxins from a historical prespective, the legal, and the state of the art in methodologies and techniques. Finally the section entitled Approaches for Prevention and Control of Aflatoxins on Crops and on Different Foods, describes actions to prevent and mitigate the genotoxic effect of one of the most conspicuous aflatoxins, AFB1. In turn, it points out interventions to reduce identified aflatoxin-induced illness at agricultural, dietary and strategies that can control aflatoxin. Besides the preventive management, several approaches have been employed, including physical, chemical biological treatments and solvent extraction to detoxify AF in contaminated feeds and feedstuffs.
