The Thanet District Council confirmed that initial reports came from three popular seaside locations—Margate Main Sands, Ramsgate Main Sands, and Botany Bay—where the unusual substance was found scattered along the shoreline and noticed by visitors over the weekend. In a statement shared on social media, HM Coastguard said the material is believed to be palm oil that has solidified after exposure to cold seawater. The agency urged the public to report any similar findings elsewhere along the coast. “Palm oil washed ashore may appear harmless, but it poses a serious risk to dogs if ingested,” HM Coastguard warned, as reported by BBC on Thursday (1/1/2026). Pet owners were advised to keep animals on leads and away from the suspected material. Thanet District Council said safety measures have been put in place, with comprehensive beach inspections scheduled for Sunday morning. Cleanup operations will begin once identification and risk assessments are completed. Palm oil spilled into the sea typically hardens in colder temperatures, forming white, wax-like clumps. While brief human contact is not considered toxic, ingestion by animals can cause serious digestive problems and may contaminate coastal ecosystems. Authorities have yet to identify the source of the spill and are coordinating with relevant agencies to investigate whether it originated from shipping activity or illegal waste disposal at sea. Visitors to eastern Kent beaches have been urged to remain vigilant and follow official guidance until cleanup efforts conclude.
