Opinion on animal health risk mitigation treatments as regards imports of animal casings – 2012
Authors EFSA Panel on Animal Health and Welfare (AWAH) Hearing expert Dr. J.J. Wijnker Journal EFSA Journal, 10(7) (2012) 2820 Summary Salting with NaCl for 30 days is a well-established and accepted procedure in the casings industry and it has been the standard animal health risk mitigation treatment prescribed in EU legislation for many years. […]
Inactivation of foot-and-mouth disease virus in various bovine tissues used for the production of natural sausage casings – 2012
Authors J.J. Wijnker, B. Haas, B.R. Berends Journal International Journal of Food Microbiology, 153 (2012) 237-240 Summary Bovine intestines, bladders, and oesophagus are used for the production of natural casings(“beef casings”) as edible sausage containers. Derived from cattle experimentally infected with FMDV (initial dosage 104 TCID50 / mL, strain A Iran 97), these beef casings […]
Virus inactivation by salt (NaCl) and phosphate supplemented salt in a 3D collagen matrix model for natural sausage casings – 2011
Authors T. Wieringa-Jelsma18, J.J. Wijnker, E. M. Zijlstra-Willems18, A. Dekker18, N. StockhofeZurwieden18, R. Maas18, H.J. Wisselink18 Journal International Journal of Food Microbiology, 148 (2011) 128-134 Summary Due to the possible presence and spread of contagious animal viruses via natural sausage casings, the international trade in these food products is subject to veterinary and public health […]
Inactivation of classical swine fever virus in porcine casing preserved in salt – 2008
Authors J.J. Wijnker, K.R. Depner17, B.R. Berends Journal International Journal of Food Microbiology, 128 (2008) 411-413 Summary Pig intestines used for the production of natural sausage casings may carry classical swine fever (CSF) virus. Feeding pigs with human food waste that contains porcine (hog) casings may then spread the virus to CSF-free animals. Casings derived […]

Krebs15 Journal Berliner und Münchener Tierärztliche Wochenschrift, 87 (1974) 410–412Die Fleischwirtschaft, 6 (1974) 1051-1053 Summary Lactic and citric acid in 0.5 and 2.0% concentrations were tested for their effect on sheep’s casing experimentally treated with foot-and-mouth disease (FMD) virus. After 0.5% lactic acid or 0.5% citric acid had been allowed to […]
Introduction
Although several studies have already been completed and published over the years, a more comprehensive approach was adopted by the ISWG in 2010, with its long-term cooperation with Wageningen Bioveterinary Research (WBVR), a renowned research institute in the Netherlands. A shift was made from using an experimental live animal model for virus inactivation studies towards […]
