Food-borne illness Flashcards
what is included in the changing epidemiology of food-borne disease
intensification and concentration of food production; changes in eating patters; changes in populations, pathogens and environment; advances in diagnostic tools
what can intensification and concentration of food production lead to
increased risk of large disperse outbreaks
what changes in eating patterns have been seen
healthier foods; ready to eat foods
what has advanced diagnostic tools led to
increased capacity to relate seemingly unrelated events
what is surveillance
ongoing, systematic collection, analysis, interpretation and dissemination of data regarding a health-related event for use in public health action to reduce morbidity and mortality and to improve health
what is surveillance
ongoing, systematic collection, analysis, interpretation and dissemination of data regarding a health-related event for use in public health action to reduce morbidity and mortality and to improve health
what are 3 uses of PH surveillance data
understand trends and patterns of disease; estimate magnitude or burden of a health problem; identify resources needed during and after PH emergencies
where is surveillance for foodborne disease done
local, provincial, national, international
where is surveillance for foodborne disease done
local, provincial, national, international
what is pulsenet canada
a large repository of PFGE data
what is foodnet canada
integrated surveillance system at sentinel sites (ontario, BC, AB);
what does foodnet canada do
monitors trends in human enteric disease, risk factors and sources of exposure within communities (retail, agriculture, animals, water)
what does CIPARS stand for
canadian integrated program for antimicrobial resistance surveillance
what does CIPARS do
monitors trends in antimicrobial use and antimicrobial resistance in bacteria from human and agri-food sectors nationally
what does CNDSS stand for
canadian notifiable disease surveillance system
what does CNDSS do
collects the number of laboratory confirmed illnesses reported to local public health units/regions to provincial public health authorities and to the national level on an annual basis
what does the enhanced national listeriosis surveillance do
collects detailed case level data from invasive listeriosis cases in participating provinces
what does the enhanced national listeriosis surveillance do
collects detailed case level data from invasive listeriosis cases in participating provinces
what pathogen causes the greatest number of illnesses for food-borne disease
norovirus
what is required for a case of food-borne illness to be reported
to be ill enough to go to the doctor; doctor requests a sample; sample is tested
what are the steps in a food-borne outbreak investigation and response
what does PFGE stand for?
pulse-field gel electrophoresis
incubation period of E. coli 0157 in humans
3-4d (range of 1-10d)
what illness does E. coli 0157 cause in humans
diarrhea (ranges from mild and non-bloody to virtually all blood)
what is a major complication of human illness with E. coli 0157
hemolytic uremic syndrome (HUS)
what is the major reservoir of E. coli 0157
intestines of cattle and other animals
how is E. coli 0157 transmitted
primarily through ingested of contaminated food or water; can also occur by people-people transmission
what are the 3 pillars of a food-borne outbreak investigation
laboratory investigation, epidemiological investigation, food safety/environmental investigation
