Biological Monitoring Public Health Agency Canada- many branches and centres including the Federal base in  Ottawa and Microbiology base in Winnipeg Speaker from the Laboratory Foodborne Zonoses department: research in minimizing the risks  of human illnesses arising from the interface between humans, animals, and the environment. Monitoring: collect water samples and test biologically: bacterial indicators, pathogens, and  microbial indicators. US recently estimated 20-25% of the population are sensitive to  waterborne disease due to other illnesses/factors leading to the populations being  immunocompromised. Distribution of waterborne outbreaks: exist even in developed countries. Cryptosporidium in  Milwaukee, USA 400,000 individuals were infected and 92 million dollars lost (including loss due  to reduced productivity). Multivarrier approach to ensure microbiologically safe drinking water 1. Protect source water 2. Water treatment 3. Manage and protect water distribution systems 4. Verify drinking water quality by monitoring WHO: there should be no lower limit for pathogens in water to be consumed. MDGs aims to  reduce by half the number of individuals drinking un-processed water. Difficult to monitor all threats. Long-term persistence in water (Viruses, Protozoa) and resistance
