A “red tide” is a common term used for a harmful algal bloom. … This bloom, like many HABs, is caused by microscopic algae that produce toxins that kill fish and make shellfish dangerous to eat. The toxins may also make the surrounding air difficult to breathe.

How does red tide affect humans?

For people with severe or chronic respiratory conditions, such as emphysema or asthma, red tide can cause serious illness. The red tide toxins can also accumulate in molluscan filter-feeders such as oysters and clams, which can lead to neurotoxic shellfish poisoning in people who consume contaminated shellfish.
