Chicken Faeces Garden Fertilizer: Possible Source of Human Avian Influenza H5N1 Infection

Abstract

P>Avian influenza H5N1 infection in humans is typically associated with close contact with infected poultry or other infected avian species. We report on human cases of H5N1 infection in Indonesia where exposure to H5N1-infected animals could not be established, but where the investigation found chicken faeces contaminated with viable H5N1 virus in the garden fertilizer. Human cases of avian influenza H5N1 warrant extensive investigations to determine likely sources of illness and to minimize risk to others. Authorities should regulate the sale and transportation of chicken faeces as fertilizer from areas where H5N1 outbreaks are reported.
