Authorities in Taoyuan City, Taiwan are investigating an outbreak of Salmonella infection (presumably SE) that has resulted in 520 diagnosed cases and 41 hospitalizations. 

Source of infection has been traced to a Vietnamese style Banh Mi food store that has been fined under laws relating to food safety and sanitation.  The vendor was responsible for a similar outbreak in late 2021.

An investigation of the outbreak showed that contaminated eggs were used to prepare mayonnaise that was not refrigerated when distributed to the food store.
