What happened

As New World screwworm returns to the US, a new dashboard tracks the risk Lisa Lock Scientific Editor Alexander Pol Deputy Editor In the 1950s, the New World screwworm cost U.S.

Why it matters

livestock producers tens of millions of dollars a year, reaching $50 million to $100 million annually in the hardest-hit Southwest, before it was eradicated from the United States and pushed south to Panama.

Common ground
