'The doctors panicked when they noticed that my red blood platelet count was sky high,' Mr du Toit said.
'The first real symptom was blood in my urine, which is when I went for blood tests. The blood test confirmed that I had Bilharzia.
'It's caused by a type of flatworm which had spent part of its life in water snails and the other part in my liver. It left me weak and in bed for weeks.'
He added: 'The high red blood platelet count signalled that I was carrying a lot of parasites. This included numerous species of internal worm parasites and a particularly nasty external worm parasite known as Hook Worm.
'This worm was actually visible under the skin of my foot and would move at night. It became a game to find the worm in my foot each morning.'
After a long stint sick in bed recovering, Mr du Toit was finally given the all clear following courses of powerful antibiotics, pesticides and by spraying liquid nitrogen on the parasites visible under his skin.
