That's very interesting reading about Hulda finding an ascaris egg floating in a glass of water... ugh! It seems impossible to avoid the eggs :( I'll be covering my water glasses from now on or drinking out of a bottle with a top on it.
By the way, when I did a series of colonic irrigation sessions... after one session ALOT of eggs were floating at the bottom of the toilet after I got up and did a final release into the toilet... it looked like about 100 eggs... I'll never forget it - and its a very hidious reminder that these critters will lay several hundred eggs at a time. You only need one to hatch for the whole horrible nightmare to start again :(
