After discussions with local growers and the South Australian Oysters Growers Association (SAOGA), PIRSA says the Coffin Bay oyster production areas will continue to be closed until next week.
As a precautionary measure, PIRSA closed the oyster growing areas early last week after a rise in Vibrio parahaemolyticus infections, with a product recall for local raw pacific oysters issued on Friday by SA Health.
Executive Director of Biosecurity with the association, Nathan Rhodes, said in a statement while the cause of the outbreak is under investigation, PIRSA may not be able to pinpoint the exact source of the virus in this case, and is taking a cautious approach to reopening growing areas.
He said they’re confident any further risk from the virus has passed, and they’re working with growers in implementing the enhanced control program, requiring growers to rapidly reduce the temperature of oysters after harvest to reduce the likelihood of vibrio bacteria.
In a statement, SAOGA says the financial impact of the outbreak in the Coffin Bay Growing Area will be devastating for the industry.
The association says the outbreak and subsequent recall is likely to cost the industry millions of dollars and will sadly result in some producers being forced to close their business.
Chairman of SAOGA, Rob Kerin, said it’s an understatement to say this is devastating in the lead up to Christmas, and they’ll certainly be speaking to the State Government about what support measures can be put in place.
