Mankato MN; Casa Grande AZ | I agree with worms.
Eggs can live in the soil 30 years.
I remember Dr. Jerry Hawton’s story about Purdue campus being built over their old hog lot, they took some dirt decades later and found viable worm eggs in it.

Raising pigs on dirt is not as sanitary as concrete that can be cleaned and disinfected.
Safeguard or Ivomec, repeat in 10 days to get the immature worms before they mature and start laying their eggs, too.
Tractor Supply sells a small bottle of Ivomec. Angle your 18x5/8 or 16x3/4 needle to administer just under the skin (SQ), not in to the muscle.
Edit, when you take your pigs to the butcher, ask to see the livers. You will see white scars on them caused by worm damage. Most butchers know what you are talking about.
Good luck!
