Michigan implements new animal transport rules to stop parasite spread

To protect its livestock and pets, the Michigan Department of Agriculture and Rural Development (MDARD) has introduced strict new animal transport rules starting June 17, 2026.
These measures aim to prevent the New World screwworm (NWS), a dangerous flesh-eating parasite, from entering the state.
While NWS has not been found in Michigan, recent outbreaks in Texas and New Mexico have prompted this proactive stance.
The screwworm is highly destructive, as it lays eggs in wounds, leading larvae to feed on living tissue.
The new regulations apply to all warm-blooded domestic animals arriving from affected regions.
Any suspected cases must be reported immediately to MDARD to ensure the health of Michigan’s animals and the stability of its agricultural sector.
