Hello charLe - The boiling water is a fine thing to do! A person will never be able to avoid all parasite infections, BUT things like disinfecting your fruits and vegetables, cutting board and utensils will help lessen the chance of picking up a parasite infection. Other things that will help are: #1 do not walk barefooted where animals have defecated #2 throughly wash hands and under nails before putting your hands in your mouth or around your face #3 when traveling abroad, do not drink the water and #4 when in doubt of the cleanliness of food that has been prepared by others (restaurant, sidewalk vendors, etc.) - DO NOT eat it!
Going overboard on precautions is not healthy - but then again, it is unhealthy to have a total disregard of parasites too!
As I have always said - live your life - be happy - and just parasite cleanse 2 times per year to STAY healthy :)
