A stray dog in Homestead was infested with screwworm, the invasive pest that is hated and feared by the agriculture industry, state officials said Monday.
It's the first case on the mainland. Screwworm was discovered last fall in the Lower Keys, the first U.S. infestation in more than 30 years.
Since then, more than 80 million sterile screwworm flies have been released in the Lower and Middle Keys. That's the proven method for eradicating screwworm.
