Regarding Re-infection

Cant find any past threads on reinfection-although im sure its my searching skills- and that just happens to be one of my biggest obstacles at the time. I know the worms and flukes tend to harbor the viruses and bacteria thereby serving as a reinfection mechanism for them....but what about the worms and flukes? Cant we just pick them up again from all sorta foods? When i killed some of my flukes they were back within days. Is the Food Zappicator the ansear to this? Is it worth the $160? Or what about a blood electrification unit? i know they can help with some worm re-infections but they cant stop all re-infection cycles right? And instead of buying the food zappicator maybe one could just buy a blood electricification unit like an SP and then zap foods with it? Three birds one stone baby!? I know the food zappicator is supposed to take care of alot of food toxins as well, but im on a strict budget and was hoping i could just do it all with a Silver pulser or something like it.

What are yall doing for breaking re-infection cycles?

I know u can zap foods with the f165 but i want to keep it busy doing its own thing so i dont have to take it apart everytime i eat a piece of fruit, u feel me.
thanks in advance for any input.
