Carlos Venegas, a local resident affected by the odors and member of the Chillán Viejo Environmental Committee, stated that "it is urgent and essential to legislate to build a regulatory framework that guarantees health and quality of life for people; otherwise, inspections will continue to be insufficient." Meanwhile, the Health Authority reported that 14 complaints regarding foul odors were registered in January 2026, prompting inspections at a pig farm and at Essbio's wastewater treatment plant.
