The American River shellfish harvesting area on Kangaroo Island has reopened following the lifting of a closure that had been put in place due to the detection of brevetoxins.
Routine testing by the South Australian Shellfish Quality Assurance Program (SASQAP), a joint initiative by the state government and the shellfish sector, has confirmed brevetoxin levels have returned to safe levels, allowing commercial harvesting to resume immediately.
This closure was the only harvesting area on Kangaroo Island that had been closed due to the current algal bloom. The closure had been implemented to protect public health after elevated levels of brevetoxins were detected.
Since 1996, SASQAP has conducted a testing regime aimed at assuring consumers of commercially harvested oysters, mussels, cockles and scallops that they continue to be safe to eat. As part of this program harvesting areas are at times temporarily closed to ensure food safety standards are upheld.
Closures remain in place at the Coobowie, Franklin Harbour, Port Vincent and Stansbury oyster harvesting areas, and the harvesting of pipis from the Coorong.
The majority of South Australia’s shellfish harvesting areas remain open and their produce is safe to eat.
PIRSA regularly engages with impacted shellfish producers during harvest area closures and, through SASQAP, continues to monitor the closed harvesting areas with the view to opening them as soon as the relevant food safety standards are met.
