People have been warned not to eat fish from the Loch Lamond Lake in Bethlehem.
Free State Health spokesperson, Mondli Mvambi, says it is believed the fish is likely contaminated and not suitable for human consumption. Reports surfaced on Sunday about dead fish found floating in the water.
Head of Health, David Motau, says they have dispatched their health environmental officers to test water samples taken from the lake in order to determine what could have killed the fish.
Provincial Head of Environmental Health and Medical Waste, Joe Mokgatle, says the contamination seems localised and to not have spread to other streams and water outlets.
“From what can be seen on the pictures that we have received thus far, is that the lake is a little bit milky and there is possible suspended matter in the water, together with possible contamination as a result of possible chemicals that spilt into that water and then secondly, we are suspecting possible sewer contamination.”
Joe Mokgatle, provincial Head of Environmental Health and Medical Waste, says Trout, Onderbek and Moggel fish species are the ones most affected by this contamination.
