The public has been warned not to pick up dead marine life or to harvest living marine resources on the coast between Umhlanga and Umdloti north of Durban.
The eThekwini municipality has issued this warning after beaches north of the city were closed following a chemical spill in the past week – when looting and violence hit the area.
