This book was released on 2013 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blackberries, genus Rubus, are an important Oregon agricultural commodity. In their fresh and processed forms, they offer many health benefits and may be able to help Americans better achieve fruit consumption recommendations because of convenience and pleasant sensory qualities. However, the susceptibility of blackberry products to contamination with bacterial pathogens of human health concern is unknown. Blackberries have never directly been implicated in a food safety incident; however, raspberries, also in the Rubus genus, have been the vehicle for hepatitis A, norovirus, and Cyclospora cayetanensis outbreaks. Furthermore, strawberries were recently the source of an Escherichia coli O157:H7 outbreak in Oregon. To better understand the potential for microbial pathogen contamination and the ability of these microorganisms to survive or grow in blackberry products, several studies were conducted. Fresh berries from the 'Obsidian' and 'Triple Crown' cultivars were evaluated at different harvest periods for the aerobic plate count, coliforms, yeasts, and molds to establish a baseline microbial population. Environmental samples were taken from a clean mechanical harvester and then from the same harvester that had been intentionally left soiled with berry harvest debris to determine the impact of harvester microbial quality. Samples from 'Marion' and 'Black Diamond' cultivars were hand harvested and evaluated for E. coli O157:H7 and Salmonella spp. by rapid detection methods via the NEOGEN® Reveal® 2.0 systems. Fresh, wild 'Himalaya' blackberries and frozen blackberries from the 'Triple Crown' cultivar were spot inoculated with Escherichia coli O157:H7, Salmonella Typhimurium, Listeria monocytogenes, and Staphylococcus aureus to determine the ability of these microorganisms to survive on the berry surface. 'Himalaya' samples were stored for 3 days at ambient temperatures and 'Triple Crown' for 6 months at -23.3°C. Lastly, juice and wine were made from 'Marion' and 'Black Diamond' purees. The juices and wines were used for pathogen survival studies using the aforementioned microorganisms to better understand what constituents of blackberries may contribute to bactericidal effects, as well as the survival patterns in these products. Aerobic plate counts for 'Obsidian' and 'Triple Crown' cultivars ranged from 3.52-4.62 log CFU/g of berry with later harvests tending to have higher values. 'Triple Crown' mid-late harvest samples were significantly higher than the early harvest samples (p = 0.005). Yeasts and molds ranged from 3.01-4.73 log CFU/g of berry with later harvests having significantly higher values for both cultivars (p = 0.048 'Obsidian'; p

Download or read book The Microbiological Safety of Low Water Activity Foods and Spices written by Joshua B. Gurtler and published by Springer. This book was released on 2014-12-08 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low water activity (aw) and dried foods such as dried dairy and meat products, grain-based and dried ready-to-eat cereal products, powdered infant formula, peanut and nut pastes, as well as flours and meals have increasingly been associated with product recalls and foodborne outbreaks due to contamination by pathogens such as Salmonella spp. and enterohemorrhagic E. coli. In particular, recent foodborne outbreaks and product recalls related to Salmonella-contaminated spices have raised the level of public health concern for spices as agents of foodborne illnesses. Presently, most spices are grown outside the U.S., mainly in 8 countries: India, Indonesia, China, Brazil, Peru, Madagascar, Mexico and Vietnam. Many of these countries are under-developed and spices are harvested and stored with little heed to sanitation. The FDA has regulatory oversight of spices in the United States; however, the agency’s control is largely limited to enforcing regulatory compliance through sampling and testing only after imported foodstuffs have crossed the U.S. border. Unfortunately, statistical sampling plans are inefficient tools for ensuring total food safety. As a result, the development and use of decontamination treatments is key. This book provides an understanding of the microbial challenges to the safety of low aw foods, and a historic backdrop to the paradigm shift now highlighting low aw foods as vehicles for foodborne pathogens. Up-to-date facts and figures of foodborne illness outbreaks and product recalls are included. Special attention is given to the uncanny ability of Salmonella to persist under dry conditions in food processing plants and foods. A section is dedicated specifically to processing plant investigations, providing practical approaches to determining sources of persistent bacterial strains in the industrial food processing environment. Readers are guided through dry cleaning, wet cleaning and alternatives to processing plant hygiene and sanitation. Separate chapters are devoted to low aw food commodities of interest including spices, dried dairy-based products, low aw meat products, dried ready-to-eat cereal products, powdered infant formula, nuts and nut pastes, flours and meals, chocolate and confectionary, dried teas and herbs, and pet foods. The book provides regulatory testing guidelines and recommendations as well as guidance through methodological and sampling challenges to testing spices and low aw foods for the presence of foodborne pathogens. Chapters also address decontamination processes for low aw foods, including heat, steam, irradiation, microwave, and alternative energy-based treatments.

This book was released on 2018-09-23 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Standards for the Growing, Harvesting, Packing, and Holding of Produce for Human Consumption (US Food and Drug Administration Regulation) (FDA) (2018 Edition) The Law Library presents the complete text of the Standards for the Growing, Harvesting, Packing, and Holding of Produce for Human Consumption (US Food and Drug Administration Regulation) (FDA) (2018 Edition). Updated as of May 29, 2018 To minimize the risk of serious adverse health consequences or death from consumption of contaminated produce, the Food and Drug Administration (FDA or we) is establishing science-based minimum standards for the safe growing, harvesting, packing, and holding of produce, meaning fruits and vegetables grown for human consumption. FDA is establishing these standards as part of our implementation of the FDA Food Safety and Modernization Act. These standards do not apply to produce that is rarely consumed raw, produce for personal or on-farm consumption, or produce that is not a raw agricultural commodity. In addition, produce that receives commercial processing that adequately reduces the presence of microorganisms of public health significance is eligible for exemption from the requirements of this rule. The rule sets forth procedures, processes, and practices that minimize the risk of serious adverse health consequences or death, including those reasonably necessary to prevent the introduction of known or reasonably foreseeable biological hazards into or onto produce and to provide reasonable assurances that the produce is not adulterated on account of such hazards. We expect the rule to reduce foodborne illness associated with the consumption of contaminated produce. This book contains: - The complete text of the Standards for the Growing, Harvesting, Packing, and Holding of Produce for Human Consumption (US Food and Drug Administration Regulation) (FDA) (2018 Edition) - A table of contents with the page number of each section

This book was released on 2008 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Problems linked with pathogens in fresh produce, including the associated public health and trade implications, have been reported in a number of countries worldwide. Furthermore, from 1980 to 2004, the global production per annum of fruit and vegetables grew by 94% and fruit and vegetables are a critical component of a healthy diet. Thus, ensuring the safety of these products is of high importance. Reported outbreaks associated with leafy vegetables and herbs have been notable for the wide geographical distribution of the contaminated products, the high numbers of consumers exposed and thus the large number of cases. This meeting addressed the pathways for contamination, survival and persistence of microbiological hazards associated with leafy vegetables and herbs, and the potential management options from primary production through to the consumer. Consideration was given to all aspects of the farm to fork continuum, i.e. pre-harvest and post-harvest.

Download or read book Post harvest Pathology written by Dov Prusky and published by Springer Science & Business Media. This book was released on 2009-12-01 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a collection of papers that includes material presented at the 2008 International Congress for Plant Pathology, this text features research right at the leading edge of the field. The latest findings are particularly crucial in their implications for fruit production; an important market sector where in some areas up to 50 per cent of the crop can be lost after harvest. While post-harvest fruit treatments with fungicides are the most effective means to reduce decay, rising concerns about toxicity have led to the development of alternative approaches to disease control, including biological methods, the subject of three chapters of this book. With several new techniques requiring modification of current post-harvest practices, it is more important than ever to stay abreast of the latest information. Other chapters deal with the mechanisms of host fruit and vegetable resistance, fungal pathogenicity factors and their relationship with the host response, and a number of subjects related to disease assessments before harvest as well as their relationship to the postharvest treatment of fruits and vegetables. The book also includes several useful case studies of crops such as kiwifruit and peaches, where different approaches at the pre- and post-harvest levels are combined to good effect. With food production issues gaining an ever higher profile internationally, this text makes an important contribution to the debate.
