A Ninth Circuit panel on Wednesday rolled back the Environmental Protection Agency's approval of the use of the pesticide streptomycin sulfate on citrus groves to fight citrus disease. The underlying lawsuit was brought by farmworkers and other interest groups, which argued the EPA had greenlit streptomycin sulfate for use on citrus plants without adequately considering potential harms from the chemical. The panel, consisting of U.S. Circuit Judges Ronald Gould and Johnnie Rawlinson ... and Daniel Bress ... partially ruled in favor of the EPA determining there was substantial evidence for the EPA's assessment concerning risks which could lead to antibiotic resistance. However, they said, the EPA's assessment concerning risks to bees and other pollinators was incomplete. In a statement after the ruling, the Center for Biological Diversity, one of the groups involved in the suit, applauded the Ninth Circuit's decision. The rollback of streptomycin approval "is a significant win for public health, farmworker safety and endangered species," [said attorney] Hannah Connor. Streptomycin sulfate is used as an antibiotic to treat serious illnesses but has also found use as a pesticide. The Center for Biological Diversity claims spraying streptomycin on citrus trees to combat citrus greening disease is "highly ineffective" and argues that its use as a pesticide violates the Endangered Species Act because it causes long-term health effects to endangered animals and plants.
