A brief history of food safety in Australia in the context of the deve
lopment of scientific knowledge is presented. Australia's food and foo
d commodity residue and contamination surveillance and monitoring prog
rams are outlined. Although chemical residues are perceived as a major
health risk by the general community, the risk of food causing illnes
s or death because of chemical residues is low. The major threat to hu
man health from food is microbiological contamination, in terms of dea
ths, sickness and economic loss. The emerging influences in food safet
y are scientific and technical developments, deregulation, social and
demographic factors, and the media. The risk of disruption of domestic
and export markets by food safety issues is considerable. The emergen
ce of international standards for food production and processing will
enable commercial contractual arrangements to minimise the frequency o
f disruptive food safety incidents.
