Workshop to Plan Research into Sources and Pathways of Rising Yersinia Infections


Yersinia infections in humans and farm animals have been steadily increasing in the last 10 years.  It is now the fourth most common source of human foodborne infection, with 1200 cases reported last year.  In 2014 there was a significant outbreak in Canterbury, Auckland, Wellington and the Bay of Plenty, which made 351 people sick and hospitalised 70.  It was strongly associated with consumption of raw carrots and lettuce, but the exact sources could not ultimately be identified.  In animals. Yersinia is largely a disease of ruminants and can cost farmers $25K to treat an average-size herd, with a total estimated financial burden to the NZ dairy sector of between $4.7M and $7.4M.

The Centre hosted a workshop in Wellington on 26 March to survey what is known, and what research needs to be carried out to learn more about disease sources and pathways in order to develop better prevention protocols.
