Four new cases of salmonella poisoning linked to a string of Vietnamese bakeries have been confirmed following an urgent warning from health authorities.
South Australia Health confirmed on Friday that the number of cases had risen to 15 and 11 people needed to be hospitalised because of the deadly disease.
The update comes the day after the health authority said they were investigating a cluster of salmonella cases linked to three Angkor Bakery stores in Adelaide's northern suburbs.

Victims of the food poisoning had fallen ill after eating Vietnamese rolls purchased at the bakeries, SA Health said on Thursday.
The salmonella cases are linked to the stores at Springbank Plaza in Burton, Hollywood Plaza in Salisbury Downs and Blakes Crossing Shopping Centre in Blakeview.
Deputy Chief Medical Officer, Dr Nicola Spurrier, said they were in the process of identifying the source of contamination.
'SA Health authorised officers, in conjunction with local council Environmental Health Officers, have inspected stores at Springbank Plaza, Hollywood Plaza and Blakes Crossing,' she said.
'Food and environmental samples have been collected from all stores, and results will assist in identifying the source of the contamination.'
Dr Spurrier said early investigations suggested the cases could be linked to raw egg butter, pate or BBQ pork ingredients.

'The businesses complied with a council request on Tuesday to cease using these ingredients and, from today, the businesses have agreed to cease selling all Vietnamese rolls until the source has been identified,' she said.
'Cleaning and sanitising procedures have also been assessed and improved, and will continue to be monitored.'
Those who have come into contact with the contaminated food may experience the symptoms between six and 72 hours after exposure.
The symptoms can last for three to seven days.
Symptoms can include fever, diarrhoea, loss of appetite, headache, stomach, cramps, nausea and vomiting.
More severe symptoms may present in young children, older people, pregnant women and people who are immunocompromised.
