From Jan. to March, 2015, two people died and an additional 30 sickened with Salmonella bovismorbificans.
New South Wales Health traced the Salmonella to a bakery that supplied aged-care facilities across the Illawarra, Shoalhaven and the ACT.
The defunct bakery, Betta Maid, was fined A$63,000 in Wollongong Court last week, plus A$20,000 in court costs, for selling unsafe food and breaching hygiene standards.
Charges brought against the company director, Udo Boschan, have been adjourned to May 26.
Betta Maid was ordered to shut temporarily in March last year, but announced in April it would close its doors for good and the company was placed into liquidation.
