SA National Parks said Friday that the "red colouring of the water seems to have subsided in some areas of the Garden Route.
However, spokesperson, Nandi Ngwdlamba, said authorities still want to test more water samples to determine whether the algal bloom which leads to red tide, is in fact subisding.
She said that four water samples were taken for analysis by Professor Brian Allanson of the Knysna Basin Project.
Ngwadlamba said the results of the tests should be available this weekend.
Earlier SanParks cautioned people about collecting and eating shellfish until the red tide clears.
Professor Allanson said shellfish should not be consumed when there is a red tide "because they are filter feeders they collect fine particles upon which they feed. The toxins in the dinoflagetllate cells are not toxic to the shellfish, but because they accumulate particles on their gills and gastric glands, if the particles are toxic, then this makes shellfish toxic as well to its consumers," he said.
The Eden District Municipality's Health Division meanwhile had visited numerous health facilities including pharmacies, hospitals, clinics in the Garden Route to ascertain if there are any cases of PSP (Paralytic Shellfish Poisoning) reported.
There have been no cases thus far, Ngwadlamba said.
