[1] The outbreak was first identified by doctors at Chris Hani and Steve Biko academic hospitals in July 2017, who notified the National Institute for Communicable Diseases (NICD) about an unusually high number of neonatal infections.

The source of the outbreak at the Enterprise Foods facility was only discovered after nine five-year-old children from Soweto were brought to Chris Hani Baragwanath Hospital in mid-January 2018.

[7] In 2024, the National Health Laboratory Service confirmed that the ST6 strain that was predominantly responsible for the outbreak was only found in Tiger Brands’ Enterprise facility in Polokwane and nowhere else.

[9] At a press conference the next day, Tiger Brands CEO Lawrence MacDougall denied responsibility, stating "There is no direct link between any of the deaths and our products."

[15] In December 2018 the South Gauteng High Court granted a certification order opening up the process for class-action lawsuit against Tiger Brands for around 1,000 claimants.
