WASHINGTON— Conservation, farmworker and public health groups filed a legal petition today urging the Environmental Protection Agency to ban use of pesticides that can promote resistance to medically important antibiotics and antifungals.

The overuse of antibiotics, which are essential to treating human disease, as pesticides on fruit and vegetable crops threatens public health because it can lead to “superbugs,” bacteria that have developed resistance to antibiotics. Similar overuse of antifungal pesticides can lead to fungal infections that are less treatable with medical antifungal drugs.

“Each year Americans are at greater risk from dangerous bacteria and diseases because human medicines are sprayed on crops,” said Nathan Donley, environmental health science director at the Center for Biological Diversity. “This kind of recklessness and preventable suffering is what happens when the industry has a stranglehold on the EPA’s pesticide-approval process.”

According to the Centers for Disease Control and Prevention, on average more than 2.8 million antibiotic-resistant infections — causing 35,000 deaths — occur in the United States each year. That means, on average, someone in the United States gets an antibiotic-resistant infection every 11 seconds, and every 15 minutes someone dies as a result.

The CDC has determined that the medically important antibiotics the EPA has approved for pesticide use on crops can facilitate antibiotic resistance in bacteria, causing increased risk of staph infections and MRSA (methicillin-resistant Staphylococcus aureus). Antibiotic resistance can lead to severe illness, prolonged hospital stays and death.
