Almost all animal meat we consume will have worms or parasites, and almost all cultures who consume raw animal products go to length to avoid them. Take for example, the traditional way to eat suhsi... Fish was fermented, then dipped in fermented soy sauce, mixed with wasabi, and then eaten with ginger, all these methods were taken in precaution of parasites.
"The word "sushi" originally meant fermented fish, and has its roots in Southeast Asia."
"Nare Sushi took a couple months to prepare, and eventually becomes consumed before the fermentation process is complete."

"Just when I thought things couldn't possibly get any worse for Andrew on this E. Coli inducing bar-b-q trip from hell, someone yanked out the animal's gall bladder, spilled the contents of its bile sac into a bowl of spices, and told him to dip raw pieces of liver into it and eat it. Whatchu talkin' bout, Willis!?:

And finally we are all familiar with cooking methods... which helps prevent people from parasitic/worm infestation.
In conclusion, it is foolish to consume meat we know harbors parasites/worms, and think there could be no possible negative effect. Of course not every consumption will be problematic, but if one consumes raw animal product, consider yourself susceptible to infestation.
Still not convinced?
