Seems to me that I have heard of folks ordering a diet solution on the internet (GUARANTEED RESULTS-You WILL LOSE WEIGHT!!) and unknowingly ended up with tapeworms. The creepiness factor is enormous.
When I went to school at UC Davis, which at the time was the only vet school in California, I would sneak into vet lecture classes. One class on parasites was enough for me to say "Never again!" to raw fish. You really don't want to see the slides I saw.
