Bluff oysters threatened by parasite – In the News

There are concerns the iconic Bluff oyster could be decimated by a parasite discovered on Stewart Island.

Bonamia ostreae has been detected at two Stewart Island oyster farms, and the Ministry for Primary Industries has put restrictions on the area to limit further spread. The Ministry has been meeting with industry members in Southland and is considering pulling up the shellfish in Stewart Island’s Big Glory Bay in an attempt to stop the parasite’s spread.

While there are no food safety issues from eating oysters infected with B. ostreae, it does have a high fatality rate among infected oysters. Those in the industry are concerned the parasite could spread to wild populations in Foveaux Strait.

MPI is expected to make a decision today about whether to pull up the oyster farms in Big Glory Bay.

The parasite detection has been widely covered by local media, including:
