Preferred provider organization
In health insurance in the United States, a preferred provider organization (PPO), sometimes referred to as a participating provider organization or preferred provider option, is a managed care organization of medical doctors, hospitals, and other health care providers who have agreed with an insurer or a third-party administrator to provide health care at reduced rates to the insurer's or administrator's clients.
European and Mediterranean Plant Protection Organization
EPPO has developed international standards and recommendations on phytosanitary measures, good plant protection practice, and on the assessment of plant protection products (pesticides). It also provides a reporting service of events of phytosanitary concern such as outbreaks and new pest records. As a Regional Plant Protection Organization, EPPO also participates in global discussions on plant health organised by FAO and the IPPC Secretariat. EPPO holds expert working groups to perform pest risk analyses on plant pests of concern to the EPPO region.
