The objective of EHS-Net is to assist State health departments in improving the delivery of environmentalhealth program services by strengthening the ability of State and local environmental health programs andprofessionals to anticipate, identify, evaluate and respond to both intentional and unintentional contaminationof the food and water supply. The mechanism to achieve this purpose is the establishment of a network ofEnvironmental Health Specialists (EHS) who collaborate with environmental health program staff,communicable disease program staff, epidemiologists, and laboratorians at the State and local levelstoidentify and prevent environmental factors that contribute to foodborne and waterborne illness anddiseaseoutbreaks. The California EHS-Net project will continue on-going research to identify environmentalantecedents to foodborne illness at restaurants, and will expand the project to include drinking water safetyas well as other aspects of food safety.
