Indicator organisms to determine the use of chilling as a critical point in beef slaughter HACCP

End of project reportDuring chilling, temperatures of carcass surfaces at different sites change over time as do other parameters such as water activity (aw), the structure of the muscle and other tissues, as the carcass enters rigor mortis. Many of these factors are known to have a major effect on cell survival and growth and must be considered in determining the influence of chilling on bacterial survival on carcass surfaces. This study aimed to determine if chilling could be used as a critical control point (CCP) in beef slaughter in relation to pathogens such as E. coli O157:H7 and L. monocytogenes, using E. coli and Listeria innocua as pathogen indicators. The present study was designed to determine the influence of (a) chilling at 10oC for 72 h on the survival of E. coli and (b) chilling at 4oC for 72 h on the survival of L. innocua inoculated at different sites on beef carcasses. Three sites (neck, outside round and brisket) were inoculated (1) immediately after dressing while hot (E. coli and L. innocua) and (2) when cold after chilling (L. innocua). The influence of changes in surface aw was also considered and their relationship to the survival of E. coli and L. innocua over time was assessed. The data are discussed in relation to the use of chilling as a CCP in beef hazard analysis (HACCP) and the monitoring of neck temperature as the most suitable CCP.National Development Pla

Control of Blown Pack Spoilage in Vacuum Packaged Meat

End of project reportBlown pack spoilage (BPS) represents a significant commercial loss to Irish meat processors. This research discovered that the organisms causing BPS are ubiquitous in the abattoir environment, making eradication very difficult. The risk of BPS is best managed through a process of regular treatment of plant and equipment with a sporicidal agent such as peroxyacetic acid, good hygiene to minimise carcass contamination and removal of the heat shrinkage stage during vacuum packaging as this activates the spores and reduces the time to spoilage.National Development Plan 2007-201

THREE ESSAYS CONCERNING THE RELATIONSHIP BETWEEN EXPORTS, MACROECONOMIC POLICY, AND ECONOMIC GROWTH

This dissertation consists of three essays that collectively investigate the relationship between exports, macroeconomic policy and economic growth. The first essay investigates the relationship between disaggregated exports and growthto address why many developing countries rely on primary goods as their main source of export income when evidence suggests they could earn higher returns by exporting manufactured goods.Using regression tree analysis, I find that although increasing manufacturing exports is important for sustained economic growth, this relationship only holds once a threshold level of development is reached. The results imply that a country needs a minimum level of education before it is beneficial to transition from a reliance on primary exports to manufacturing exports. Thesecond essay explores the impact of fiscal episodes on the extensive and intensive margins of exports for a sample of OECD countries. In general, a fiscal stimulus in an exporting country is associated with a substantial decrease in each margin. However, a fiscal consolidation in an exporting country is associated with a large increase in the extensive margin, yielding a positive net effect on total exports. This positive effect of a consolidation disappears when an importing country simultaneously experiences a fiscal episode. Overall, the effect of fiscal episodes on total exports and the export margins yield important ramifications for policy-makers. The third essay takes a broad perspective in characterizing the relationship between disaggregated exports, macroeconomic policy, and economic growth. Few studies consider that macroeconomic policy may influence growth, at least partly, through the export channel and none consider that this impact may differ for primary and manufacturing exports. I first explore the determinants of disaggregated exports to empirically test whether macroeconomic policy influences the size of the export sector in a country. Second, I use simultaneous equations methods to identify the impact of macroeconomic policy and exports on economic growth. Indeed, there appears to be some evidence that macroeconomic policy may affect the level of exports. Moreover, exports appear to exert an influence on growth, but the role of macroeconomic policy in the growth process seems to be only through its influence on other variables
