Red tide is also called the harmful algal bloom phenomenon, referring to the unusual growth of colonies of toxic and non-toxic algae in the water, some of which produce toxins that harm certain types of sea life, according to BFAR.

Although red tides may be harmless, it can possibly cause human illnesses that can be debilitating or even fatal.

The agency issued an advisory saying all kinds of shellfish and krill-like prawns from an area under red tide alert must not be harvested, sold, or eaten.
