Can you eat fish that come from a HAB?

Harmful algal blooms release toxins that can accumulate in fish tissue, making fish from affected waters unsafe to eat. The risk persists during the bloom and for a period after it ends, which is why guidance commonly recommends not eating fish caught in HAB waters and waiting about two weeks after the bloom disappears before consuming fish from those areas. Cooking does not reliably destroy these toxins, so simply boiling or cooking won’t make the fish safe. The other ideas—that fish are safe during a HAB, that boiling would make them safe, or that deep-water sourcing changes the risk—don’t reflect how HAB toxins behave and therefore aren’t appropriate.
