Harmful algal blooms (HABs) and the toxins they produce, threaten drinking water safety worldwide, and here in the US, we are becoming more aware of the issue as HABs are reported across the country. Microcystins, the most common toxins arising from HABs, can put animals and humans at risk. Human reactions to microcystins include mild skin rash,
