Town of Surf City Fire Department issued the following announcement on Aug. 14.
We do have confirmed portuguese man-of-war sightings and people being stung with one person being transported to the hospital by ems. Man-of-war tentacles have coiled stingers that have a very powerful and painful toxin. If you find one washed up on the beach, don't touch it. Even dead man-of-wars or detached tentacles can sting.
If you are stung, rinse the area with saltwater. Apply concentrated vinegar solution if available. This will inactivate the stingers and prevent the release of more toxin. Then with a gloved hand or tweezers try to remove the tentacles.
Put the affected area in hot saltwater for about 20 minutes.
Call 911 for moderate to severe reactions
