Range of Surveillance Data
“environmental scanning”: living in and
knowing the community/local knowledge
anecdotal reports from members of the
public, government and non-
government agencies
formal reporting systems and analyses
Active and Passive
active : e.g. monitoring of water quality
passive : e.g. food complaint reporting
Each has its place....
The Ecology of Health; Everything
is Related
Personal hygiene and its potential impact
on food safety and water quality
quality of drinking water, recreational
water, and food premises and the risk of
food and waterborne infections
land use patterns and the quality of
drinking water and recreational water
Agreement Needed
definitions for „case‟ or „event‟
thresholds for action
what actions to take
ideally national guidelines
And so....
Comprehensive surveillance is
always going to be a worthwhile,
but probably unachievable, goal
