New Zealand Food Safety is warning the public not to consume shellfish from the Northland west coast due to the high risk of paralytic shellfish toxins. This warning is in place due to high levels of toxin-producing phytoplankton in the seawater in the area, and shellfish may contain toxins over the safe limit. The warning also includes advice on how to safely consume other seafood, such as pāua, crab, crayfish, and finfish.
