A significant number of emerging and re-emerging waterborne zoonotic pathogens have been recognized over recent decades. SARS, E. coli O157: H7, and Cryptosporidium provide examples of zoonoses with waterborne routes of transmission. Developed from an expert workshop of 29 scientists, this book provides a critical assessment of current knowledge about waterborne zoonoses and identifies strategies and research needs for controlling future emerging waterborne zoonoses. The report provides guidance to agriculturists, veterinarians, worldwide health agencies, and water providers to anticipate potential future waterborne disease problems and to determine whether current practices will be protective or whether new approaches need to be deployed to better protect the health of both humans and animals.
