At least six Tasmanians suffered food poisoning while playing at Adelaide Oval, with three of them forced out of their Sheffield Shield match in Hobart.
Traces of salmonella and the viral infection norovirus have been found in the ill cricketers.
South Australian hosted Tasmania in a Sheffield Shield match which ended last Saturday, while Australia and Sri Lanka are on Thursday playing the last of two one-day internationals finals in Adelaide.
The Adelaide Oval kitchen and players dining area passed a SA Health inspection on Thursday.
“Traces of salmonella and a virus called norovirus are showing in tests from Tasmania,” SACA chief executive Keith Bradshaw said in a statement.
“But SA Health is continuing its investigation and the source and exact cause of the contamination is still unknown.”
Bradshaw said Australian and Sri Lankan teams were advised of the investigation “as a matter or courtesy, but no reports of illness have been made by either team”.
SA Health told the SACA no further action was required, with inspectors also reviewing food handling and cleaning processes. (AAP)
