The Norwegian Institute of Public Health in collaboration with the Norwegian Veterinary Institute have jointly confirmed that the outbreak of Salmonella Enteritidis diagnosed in 22 cases was due to an imported consignment of beef from Germany.  The vehicle of infection was the improperly cooked beef resulting in the outbreak among patients aged 11 to 91 years in ten areas of the Nation.   Currently a traceback is in progress to determine the extent of distribution of the implicated beef to be recalled.
