After attending a dog show in Norrköping, Sweden in the first weekend of June, two Swedes are confirmed as being infected with enterohemorrhagic Escherichia coli (EHEC). The dog show had about 120 participants, so health officials are expecting many more cases stemming from this event. In addition, several dogs have come down with stomach pains, which may mean that they were infected as well. The National Food Administration and the Swedish Institute for Communicable Disease Control are trying to determine the outbreak source.
