Unexpected Harmful Algal Bloom in Southern Chile, more than a Public Health Issue that Might Not Go Awa

Harmful micro algal blooms (HABs) are a natural component of seasonal cycle of photosynthetic organisms in marine ecosystems. HABs are considered natural occurring phenomena that can be influenced by anthropogenic activities in coastal areas. Also, global warming, particularly changes in the oceans could increase HAB occurrences, thus enhancing the likelihood of seafood (e.g. shellfish) consumption poisonings.
