The Colchester Oyster Feast is kind of a big deal. Dating back to the 14th century and boasting a couple of to-be-kings as former guests (King Edward VIII and King George VI) it is the place to be in October. The event even has its own Wikipedia page.
And in 2013, it also was the source of an outbreak.
According to the Essex County Standard, 54 attendees became ill after eating Irish oysters at the annual festival.
A total of 200 guests attended the civic event at Colchester’s Moot Hall last October.
Within days, 13 guests reported they were unwell and an investigation was launched by Public Health England.
Questionnaires were sent out and 54 people reported they had been sick, including Colchester Council chief executive Adrian Pritchard.
