MUTTONTOWN - The state Department of Environmental Conservation (DEC) is warning residents about a dangerous plant that's making a comeback in Nassau County.

Officials say the invasive plant, called giant hogweed, can cause blindness, third-degree burns and blisters. They say the plant is spreading across the state and has been spotted at the Muttontown Preserve.

The county says it's done its best to eradicate hogweed, which was brought to the U.S. from Eurasia and can grow to be up to 20 feet tall.

DEC officials are asking anyone who sees the weed to contact them at 845-256-3111.
