In Limpopo, health authorities are expected to publish the details of their PPE tenders this week.
Provincial health department spokesperson Neil Shikwambana said, so far, R420 million had been spent on PPE.
Shikwambana also denied reports suggesting Health MEC Phopi Ramathuba's involvement in tender processes.
"MEC Ramathuba is the political head of the Limpopo Department of Health and she has no role in the supply chain management process and she knows her boundries and limitations very well. She does not have any administrative role to play within the procurement processes.
"The department is committed to clean tender administration and even here it has followed all supply management prescripts in the awarding of PPE contracts. To this end, the department has submitted the list of appointed contractors to treasury and auditor general as required by the instruction notes," he said.
