Authors EFSA Panel on Biological Hazards (BIOHAZ) Journal EFSA Journal, 12(2) (2014) 3554 Summary Bovine intestines and mesenteries in the European Union (EU) have to be removed from the food and feed chain. The opinion provides a quantitative assessment of the Bovine Spongiform Encephalopathy (BSE) infectious load that might enter the food and feed chain…

Authors EFSA Panel on Biological Hazards (BIOHAZ) Journal EFSA Journal, 9(3) (2011) 2104 Summary The opinion reviews a 2007 opinion of the French Food Safety Agency (AFSSA), which, referring to the current situation in France, concluded that the current removal of the whole intestine from bovine animals of all ages as specified risk material could…

Authors EFSA Panel on Biological Hazards (BIOHAZ) Journal EFSA Journal, 1317 (2009) 1-19 Summary According to Regulation (EC) No 999/2001 certain ruminant tissues, designated as Specified Risk Material (SRM), must be removed from the food and feed chain to protect the health of consumers against the risk of BSE. The intestines, from the duodenum to…

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…

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…

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…

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…

Authors P.A. Koolmees, M.H.G. Tersteeg, G. Keizer, J. van den 37, R. Bradley Journal Journal of Food Protection, 67 (2004) 2747-2755 Summary This study was intended as a complement to the previous reports and showed conclusively that the traditional manual cleaning and the mechanical processing of sheep intestines completely remove all lymphoid tissue that could…

Authors P.A. Koolmees, B.R. Berends, M.H.G. Tersteeg36 Report VVDO Report No. H0204 (2002) Summary This study, conducted in 2002 at Utrecht University, the Netherlands, gave a clear indication of the risk reduction due to the cleaning process of sheep intestines in comparison to meat on-the-bone, such as a leg of lamb. Some conclusions made: “When…
