A Salmonella outbreak in Australia has sickened at least 60 people and is linked to custard-filled pastries.

According to Australia’s ABC news, public health authorities are testing samples from two Adelaide bakeries and investigators suspect that the source of the the infections may be custard-filled berliner buns and custard-filled cannolis and eclairs.

Nearly half the people who have fallen ill have required hospitalization, the news report said.

Authorities with South Australia Health told the news station that they have taken more samples from the two bakeries and expect more test results later in the week. They are continuing to interview case patients to see what common foods they have eaten.
