Communities in Pogson Bay, St. Kitts, are raising concerns as large amounts of Sargassum seaweed continue to pile up along local beaches.

Officials say residents are worried about hygiene and sanitation issues, as decomposing Sargassum releases leachates containing toxic elements, including hydrogen sulfide, methane and ammonia. Experts warn that these substances can harm marine life, seep into groundwater and contaminate coastal aquifers.

While Sargassum is increasingly used in commercial products such as fertilizers, textiles, pharmaceuticals and food, experts note that this also raises concerns over the possible transfer of pollutants through the food chain.

The government, in collaboration with the Ministry of Environment and Sustainable Development led by Dr. Joyelle Clarke, has been working with residents to clean affected beaches and bays. Officials say continued clean-up efforts are essential and are calling on the public to lend their support.

Authorities stress that tackling the Sargassum problem will require cooperation between government agencies, community members and partners to protect the country’s coastline and public health.
