"We take this very seriously."He flew over the area and says only a sheen was visible on the water and no oil was found washed up on beaches."I will go again tomorrow. We won't just leave it," he says.Meanwhile, the affected penguins are being treated at the South African Marine Rehabilitation and Education Centre (Samrec) in Port Elizabeth and the Southern African Foundation for the Conservation of Coastal Birds (Sanccob) in Cape St Francis."We are treating 69 penguins and they will be washed as soon as they are strong enough," Juanita Raath, rehabilitation co-ordinator at Sanccob said.After they are cleaned, it takes about two to three weeks for them to regain their waterproofing. "They are then given health clearance and released."She says they are in need of towels and newspapers for the cleaning process and people can drop these items off at their office or at the Wimpy in Jeffreys Bay.
