As a result of algae in the water, paralytic shellfish toxins have been detected in shellfish at levels over the safe limit set by MPI.
Algae are a diverse group of organisms ranging from large seaweed to tiny Phytoplankton.
Most are harmless and are a food source for some marine life however, about 2% of algae species are capable of causing harm.
Northland District Health Board together with The Ministry of Primary Industries work side by side to educate the community about the effects algae bloom and PSP have on our Kaimoana.
