Yersiniosis is the second most frequently notified foodborne illness in New Zealand. While Y. enterocolitica BT 1A accounts for approximately 20–30 percent of annual notifications, it lacks several recognized virulence genes, which has historically raised questions about its ability to cause illness.
The UK Government is proposing the addition of several foodborne and waterborne viruses, bacteria, and parasites to the list of notifiable causative agents under the Health Protection Notification Regulations, for which laboratories testing human samples are required to report positive test results.
