An antibiotic-resistant bacteria was discovered for the first time in Los Angeles County wastewater and experts are concerned, saying the fast-spreading bacteria poses health risks, especially for the immunocompromised. The super bacteria was found by a USC professor and his team at the two largest wastewater facilities in L.A. County — Hyperion Water Reclamation Plant in Playa del Rey and the Joint Water Pollution Control Plant in Carson. The bacteria and its associated gene renders colistin, a “last resort” antibiotic, completely ineffective. Colistin is used for serious infections or conditions that can’t be treated with, or haven’t responded to antibiotics like penicillin. KTLA's Chris Wolfe reports on April 6, 2023.
