NEWTON, N.H. (AP) – A potentially toxic algae has hit a third pond in New Hampshire, and authorities have closed it.

The cyanobacteria was discovered Tuesday near the town beach in Country Pond. State environmental officials are advising the public to avoid the water and keep pets away.

Showell Pond in Sandown and Willand Pond in Somersworth were closed this month because of the algae. It contains toxins that can cause everything from skin irritation, vomiting and diarrhea to liver and central nervous system damage.
