United States
Toxic Algae Bloom
Mississippi closed the last of its 25 mainland beaches along the Gulf Coast this week due to a toxic algae bloom. Officials from the state’s Department of Environmental Quality say exposure to toxic algae bloom may cause rashes, stomach cramps, nausea, diarrhea, and vomiting and may also affect the liver and nervous system. The thick blue-green algae has already killed off oyster beds. The bloom occurred after weeks of heavy rainfall contaminated the gulf’s saltwater with freshwater. Officials in neighboring Louisiana have also issued advisories for a large bloom in Lake Pontchartrain.
