“The ones that occurred last week,” he said, “those blooms had, quite high micro-cystine toxin concentrations.”

“You should always avoid any contact with a suspicious or a confirmed harmful algal bloom because of the risks that they present,” said Launer.

Signs of illness may include breathing difficulties, nausea, vomiting, and diarrhea in people. Animals may have difficulty breathing, and convulsions and within minutes or hours of exposure.
