Most of the dead shellfish that washed ashore at Waihi Beach this week have now been removed.
Local residents were shocked when they encountered "millions" of dead shellfish washed ashore on the northern end of Waihi Beach on Tuesday.
Jeanette McCallum believed they were pipi and posted a video of the finding online, sparking thousands of views and hundreds of comments.
She said today that most of the shellfish had already been washed away now but they had begun to smell "horrible" while they were there.
"It's amazing how the ocean manages to clean itself," she said.
"[My husband] noticed last night men taking samples and digging in the sand."
The Ministry of Primary Industries said it was in discussions with the Bay of Plenty Regional Council about the incident but the cause of the mass death was unlikely to be known before next week.
She said the council had collected samples and couriered them to the ministry for disease testing, which was standard practice in mortality events such as this.
"It is important to rule out any disease cause," the spokeswoman said.
The samples were expected to arrive today and the ministry planned to run tests on them tomorrow, and would likely conduct testing on further samples early next week, she said.
"At this stage it is considered that flooding with freshwater is the most likely cause of the event. This is not uncommon with flood conditions."
The spokeswoman also confirmed the affected shellfish were actually tuatua, not pipi.
"In terms of eating the affected shellfish, MPI recommends people leave them alone. Standard health safety advice regarding shellfish is that you do not consume obviously sick or dead animals."
In a statement released this afternoon, the Bay of Plenty Regional Council said staff from the council and the University of Waikato would be analysing the shellfish for toxins.
Professor Chris Battershill, chairman in coastal science, said it was likely a number of factors contributed to the die-off.
"Apart from the weather bomb that hit the area last week, higher ocean temperatures are being recorded in this area and there have been some large sea swells," he said.
"It is also possible that this is a natural die-off due to stress from overcrowding as there is a very large population of shellfish densely packed just off the beach in this area."
Despite the huge amount of shellfish that died, Mr Battershill said there were many live shellfish within the wave zone.
The council expected to have results within three or four weeks.
"Official" government cronies posing as scientists are being told to say something like temperature, red algae, or some explanation. Anything other than microplastics, radiation, herbicides or petrochemical toxification. Perhaps the dead whales with wads of plastic in their stomach think differently.
Hyper consumption suppliers are destroying the food chain for the love of money. Meanwhile, instead of working on cleaning up the trash in the ocean, trillions have been spent lining the pockets of war supply manufacturers, public brainwashing and entertainment.
Thorosiousd "It's amazing how the ocean manages to clean itself," Even more amazing how well it cleans itself of life when helped by Melting Nuclear Plants, Naval Sonar, and Harp.
Kind of like how the coral reefs began melting after the Pacific Missile Range Facility at Kauai, Hawaii suddenly became the site for another ocean cleaning program starting with the coral reefs, and which just like the dying Sea Lions and other the bones of other marine vertebrates have also dissolved to mush.
Isn't it interesting how coral, sometimes used for bone reconstruction, also just happens to have begun desolving when that military facility began using HARP. I'm sure it's all just a coincidence. Simply a case of the ocean deciding to cleanse itself of life after 4 billion years. [Link]
