TSE risk assessment for use of bovine casings – 2008
Authors P. Comer Report DNV Report No. 22926377 (2008) Summary This study presents the results of a risk-based approach to estimate the potential exposure to BSE infectivity from the consumption of sausage casings made from bovine intestine, assuming that the casings are sourced from within the EU. Its results show that the exposure for a […]
Opinion on quantitative histological studies and the re-assessment of the BSE related risk of bovine intestines after processing into natural sausage casings – 2007
Authors EFSA Panel on Biological Hazards (BIOHAZ) Journal EFSA Journal, 464 (2007) 1-14 Summary The Institute for Risk Assessment Sciences (IRAS) and the Department of Farm Animal Health of Utrecht University produced a report on quantitative histological studies of bovine small intestine before and after processing into natural sausage casings. The report concludes that commercially […]
Quantitative histological analysis of bovine small intestines before and after processing into natural sausage casings – 2008
Authors J.J. Wijnker, M.H.G. Tersteeg, B.R. Berends, J.C.M. Vernooij38, P.A. Koolmees Journal Journal of Food Protection, 71 (2008) 1199–1204 Summary A histological study was undertaken to determine the efficiency in the removal of the mucosa and Peyer’s patches by standard processing of bovine intestines into natural sausage casings. The second objective was to calculate the […]
Histology of bovine natural casings – 1998
Authors P.A. Koolmees Report VVDO Report No. 9806 (1998) Summary Aggregations of lymph nodes or patches of Peyer are mainly present in the ileum part of the bovine small intestine. In practice, the ileum is not used as a sausage container. Isolated lymph nodes and some patches of Peyer also occur in the duodenum and […]
