Hauls of seaweed washing ashore "contain flesh eating bacteria" that can cause "leaky gut syndrome", scientists have revealed.
Beaches along South Florida, US, are being filled with Sargassum which is a thick, brown algae that releases a pungent rotten egg smell as it decays in the sun, according to a new study from Florida Atlantic University.
Scientists believe the seaweed interacts with plastic debris and Vibrio bacteria in the ocean and can pose a "pathogen storm" to holidaymakers.
