Tag: Algae poisoning

Some varieties of blue-green algae, scientifically known as cyanobacteria, produce toxins that can be extremely harmful to humans, pets, and livestock. Exposure to these toxins, especially during dense algal blooms, can lead to a range of mild to life-threatening side effects, including severe gastrointestinal distress, skin irritation, and even liver or nervous system damage.

According to the Centers for Disease Control and Prevention (CDC), harmful algal blooms (HABs) have been reported in all 50 U.S. states and are increasingly common globally, making it critical to know what algae is not edible. While some seaweed is a nutritional superfood, many algae varieties, particularly those that form HABs, can produce potent toxins that are hazardous to humans and animals.
