Selected AbstractsN -3 enrichment of pork with fishmeal: Effects on production and consumer acceptabilityEUROPEAN JOURNAL OF LIPID SCIENCE AND TECHNOLOGY, Issue 8 2008Stelios Sioutis Abstract This study aimed to develop pork products of acceptable organoleptic quality enriched with long-chain n -3 polyunsaturated fatty acids (LC n -3 PUFA). Female pigs were fed a finisher diet containing 15% PorcOmegaÔ tuna fishmeal or a commercial diet. Pigs and rations were weighed weekly. The feed conversion ratio was significantly lower in pigs fed fishmeal than in controls (2.61,±,0.01 versus 2.96,±,0.06, p,<0.05). After 6,weeks, the pigs were butchered and the fatty acid contents of selected pork products were analyzed by gas chromatography. Shelf life was tested by thiobarbituric acid-reactive substances (TBARS), initially and after 5,days of cold storage, and sensory qualities were evaluated after cooking. LC n -3 PUFA contents of pork products from pigs fed fishmeal were higher than in controls (steak 300%, stir-fry 250%, diced 520%, mince 480%, sausage 360%; p,<0.05 in all cases). There were no differences between n -3-enriched and regular pork in either TBARS content of stored raw products or sensory characteristics after cooking. Incorporating fishmeal in the finisher diet resulted in greater feed efficiency and production of nutritionally enhanced pork products with organoleptic profiles and stability comparable to those of regular pork. [source] Molecular epidemiology of Yersinia enterocolitica infectionsFEMS IMMUNOLOGY & MEDICAL MICROBIOLOGY, Issue 3 2006Maria Fredriksson-Ahomaa Abstract Yersinia enterocolitica is an important food-borne pathogen that can cause yersiniosis in humans and animals. The epidemiology of Y. enterocolitica infections is complex and remains poorly understood. Most cases of yersiniosis occur sporadically without an apparent source. The main sources of human infection are assumed to be pork and pork products, as pigs are a major reservoir of pathogenic Y. enterocolitica. However, no clear evidence shows that such a transmission route exists. Using PCR, the detection rate of pathogenic Y. enterocolitica in raw pork products is high, which reinforces the assumption that these products are a transmission link between pigs and humans. Several different DNA-based methods have been used to characterize Y. enterocolitica strains. However, the high genetic similarity between strains and the predominating genotypes within the bio- and serotype have limited the benefit of these methods in epidemiological studies. Similar DNA patterns have been obtained among human and pig strains of pathogenic Y. enterocolitica, corroborating the view that pigs are an important source of human yersiniosis. Indistinguishable genotypes have also been found between human strains and dog, cat, sheep and wild rodent strains, indicating that these animals are other possible infection sources for humans. [source] An updated review of Listeria monocytogenes in the pork meat industry and its productsJOURNAL OF APPLIED MICROBIOLOGY, Issue 1 2006D. Thévenot Abstract Pork meat and processed pork products have been the sources of outbreaks of listeriosis in France and in other European countries during the last decade. The aim of this review is to understand how contamination, survival and growth of Listeria monocytogenes can occur in pork meat products. This study discusses the presence of L. monocytogenes in raw pork meat, in the processing environment and in finished products. The prevalence of L. monocytogenes generally increases from the farm to the manufacturing plants and this mainly due to cross-contamination. In many cases, this pathogen is present in raw pork meat at low or moderate levels, but foods involved in listeriosis outbreaks are those in which the organism has multiplied to reach levels significantly higher than 1000 CFU g,1. In such cases, L. monocytogenes has been able to survive and/or to grow despite the hurdles encountered during the manufacturing and conservation processes. Accordingly, attention must be paid to the design of food-processing equipment and to the effectiveness of the cleaning and disinfecting procedures in factories. Finally, the production of safe pork meat products is based on the implementation of general preventive measures such as Good Hygiene Practices, Good Manufacturing and the Hazard Analysis Critical Control Point. [source] Prevalence of verotoxin-producing Escherichia coli (VTEC) and E. coli O157:H7 in French porkJOURNAL OF APPLIED MICROBIOLOGY, Issue 1 2002J. Bouvet Aims:,To determination the prevalence of VTEC in pork products and the surrounding environment of the pork plant (slaughterhouse and cutting plant), and characterization of the VTEC strains isolated (virulence genes and serotype). Methods and Results: ,Among the 2146 carcass and pork samples and 876 environmental samples (swabs of surfaces or materials), 328 (15%) and 170 (19%) were PCR-positive for stx genes respectively. VTEC strains were recovered from positive samples by colony hybridization or immunoconcentration, serotyped and genetically characterized. Strains of E. coli O157:H7 were not isolated from 3 uidA-positive samples detected by PCR. The VTEC isolates did not harbour eae, ehx and uidA genes. Conclusions: ,Pigs and pork meat may contain VTEC strains but characterization of the strains based on virulence factors showed that the potential danger of pork meat appears to be low since although all strains harboured a stx gene, they did not have other virulence genes. Significance and Impact of the Study:,General hygiene measures appear to be sufficient and specific hygiene measures for VTEC are not necessary at this time. The porcine VTEC strains isolated in our study probably do not present a hazard. [source] Marketing natural pork: An empirical analysis of consumers in the mountain regionAGRIBUSINESS : AN INTERNATIONAL JOURNAL, Issue 4 2002Jennifer Grannis The demand for organic meats, including beef and chicken, has grown dramatically in recent years. Yet, there are few branded pork products. This research examines the potential market for natural pork in the Intermountain West, with emphasis on targeting the market segment most likely to purchase this product at a significant premium. High-income, frequent pork consumers, and those that have purchased natural beef are most likely to purchase natural pork products. With respect to production-related attributes, those concerned about feed additives, and to a lesser degree, the effects of pork production on the environment, are likely target markets.

[source] Unexpectedly high incidence of indigenous acute hepatitis E within South Hampshire: Time for routine testing?JOURNAL OF MEDICAL VIROLOGY, Issue 2 2008Aminda N. De Silva Abstract Hepatitis E indigenous to developed countries (hepatitis EIDC) is a form of hepatitis E in persons with no travel history to highly endemic areas. It has been recognized recently as an emerging clinical entity in a significant number of economically developed countries including UK. However, it is still perceived as a rare disease and routine laboratory testing for hepatitis E is not performed. A series of 13 cases of hepatitis EIDC, diagnosed in a 13-month period from June 2005 within a single center in South Hampshire, UK, is presented. These patients were identified after implementing a novel-screening algorithm that introduced routine hepatitis E serological investigations. Patients were middle aged or elderly and males were affected more commonly. Four patients (31%) required hospital admission. All reverse transcriptase-polymerase chain reaction (RT-PCR) confirmed cases carried hepatitis E virus (HEV) genotype-3, which bore close sequence homology to HEV circulating in UK pigs. None of these patients recalled eating undercooked pork products or close contact with pigs during the 2 months preceding the onset of acute hepatitis. In comparison, during the same period, only two cases of hepatitis A and five cases of acute hepatitis B were diagnosed. These data illustrate the importance of introducing routine hepatitis E testing in all patients with unexplained acute liver disease and absence of relevant travel history. Routine testing can clarify hepatitis E epidemiology whilst improving the clinical management of patients with acute liver disease. J. Med. Virol. 80:283,288, 2008. © 2007 Wiley-Liss, Inc. [source] Proactive consumer consultation: the effect of information provision on response to transgenic animalsJOURNAL OF PUBLIC AFFAIRS, Issue 3-4 2005David Castle A national study is reported which proactively engaged 1365 Canadian consumers and solicited their opinions concerning new transgenic salmon and pork products which have not yet entered the marketplace. Respondents were methodically requested to provide initial free-association responses, and then scaled responses to product concepts about which progressively more information was revealed. This combined qualitative and quantitative method was pursued in order to determine initial knowledge levels and subsequent responses with a minimal amount of cueing via question probes. The results indicate that disclosure concerning benefits and risks of these new technologies did not harm judgements about them or estimates of purchase intent. A significant determinant of opinions was the gender of the respondent. Females were more negatively predisposed overall to the concepts and more sensitive to specific information regarding product benefits and risks. The research offers a methodological template for public consultation and communication pre-testing for new biotechnological products. Implications for regulatory policy and information dissemination for new food biotechnology products are discussed. Copyright © 2005 John Wiley & Sons, Ltd. [source] Traceability in the Canadian Red Meat Sector: Do Consumers Care?CANADIAN JOURNAL OF AGRICULTURAL ECONOMICS, Issue 1 2005Jill E. Hobbs Increased traceability of food and food ingredients through the agri-food chain has featured in recent industry initiatives in the Canadian livestock sector and is an important facet of the new Canadian Agricultural Policy Framework (APF). While traceability is usually implicitly associated with ensuring food safety and delivering quality assurances, there has been very little economic analysis of the functions of traceability systems and the value that consumers place on traceability assurances. This paper examines the economic incentives for implementing traceability systems in the meat and livestock sector. Experimental auctions are used to assess the willingness to pay of Canadian consumers for a traceability assurance, a food safety assurance, and an on-farm production method assurance for beef and pork products. Results from these laboratory market experiments provide insights into the relative value for Canadian consumers of traceability and quality assurances. Traceability, in the absence of quality verification, is of limited value to individual consumers. Bundling traceability with quality assurances has the potential to deliver more value. La traçabilité accrue des produits et des ingrédients alimentaires dans la chaîne agro-alimentaire a été mise en valeur dans les récents projets de l'industrie canadienne du bétail et représente un aspect important du Cadre stratégique pour l'agriculture (CSA). Bien que le concept de traçabilité soit habituellement et implicitement associéà la sécurité et à la qualité alimentaires, très peu d'analyses économiques se sont penchées sur les fonctions des systèmes de traçabilité et sur la valeur que les consommateurs accordent aux garanties de traçabilité. Cet article étudie les stimulants économiques de la mise en ,uvre des systèmes de traçabilité dans l'industrie de la viande et du bétail. Des ventes aux enchères expérimentales permettront d'évaluer si les consommateurs canadiens sont prêts à payer pour obtenir une garantie de traçabilité et de sécurité alimentaire ainsi qu'une garantie de méthode de production chez les éleveurs de b,uf et de porc. Les résultats de ces expériences obtenues dans ces marchés de laboratoire fourniront un aperçu de la valeur relative des garanties de traçabilité et de qualité pour les consommateurs canadiens. En l'absence de vérification de la qualité, la traçabilité ne présente que peu de valeur pour les consommateurs. Par contre, une plus grande valeur lui serait accordée si elle était associée à la garantie de la qualité. [source] | |||||||||||||
