Claimant: Roger Marshall (R)
Claim: Migrants from Central America brought screwworm into the U.S. on their pets or bodies.
Rating: FALSE
Explanation: Experts said there is no data showing migrants spread screwworm in a meaningful way. Human cases are rare, and although illicit livestock movement may have contributed, it does not explain the outbreak’s origin.
