Scientists have found a contaminated ingredient used in milkshakes was likely to blame for a Yersinia outbreak in an Australian state.
In January 2023, an outbreak of Yersinia enterocolitica in residential aged care facilities was identified by the Gold Coast Public Health Unit and confirmed using whole genome sequencing.
There were 55 cases, including six staff. Sick residents ranged in age from 54 to 101 with a median of 87 years old. 41 females and 14 males were affected. Date of onset was known for 46 cases and ranged from Jan. 16 to Feb. 17, 2023, with a peak in late January. No cases went to the emergency department. One person, who was ill prior to Yersinia infection, died.
