Is beef with liver flukes safe to eat?

Q:

I'm in the process of buying some grassfed beef through an Oregon coast farmer on Craigslist. The beef was recently processed and is ready to pick up, however we won't be getting any liver as the cows had liver flukes. I'm wondering if liver flukes affect the rest of the animal/meat quality and safety.

A:

The flukes will not affect the safety of the beef from affected animals. If the infection was severe the animals may be unthrifty and thin, which could affect beef quality by lowering the fat and marbling of the meat.
