This is part of the parasite die off, gotta say being a farmer organic or not your meat cows will still get worms. Have a read through people trying to treat these with natural remedies. You think it going to work on a cow. parasites crawl to the top of grass and cow eats it, you eat cow. Pretty simple. Some raw meats carry lots of liver fluke. You have literally opened a can of worms and unfortunately they are in you.
